Drought stress is a major problem in upland rice grown areas under rainfed conditions. It affects plant growth and development, and eventually leads to a considerable yield reduction. The study was carried out with the aim of evaluating the effect of drought stress duration on the growth characteristics and yield components of upland rice varieties. The experiment was conducted at the University of Eldoret with Sixteen upland commercial and local rice varieties were used in the study obtained from Kenya and Liberia. Rice plants were subjected to drought stress treatments at tillering and flowering stages in the green house. The experiment was layout in a complete randomized design (CRD) in a split plot arrangement with five treatments and replicated three times. The results of leaf rolling, plant height, days to 50% flowering, days to maturity, panicle number, spikelet sterility, biological yield, leaf relative water content,1000-grain weight, harvest index and grain yield revealed that there were significant differences as a result of water stress on the treatments (p≤0.001) and rice varieties (p≤0.05). All the sixteen varieties were significantly affected by the treatments when compared with the control. The results also revealed that MWUR, Dourado, L-22, Komboka, Jaowo, LAC-23, Kpatawee, MWUR, White rice and Red Youmo varieties were significantly affected by the water stress treatments at leaf rolling, flowering and maturity then that of NERICA 1,2 ,3, 4, 10,11 and 14 at tillering and flowering stages. The findings of this study indicated that NERICA 1, 2, 3, 4, 10 varieties were less affected by soil water stress treatments amongst the tested varieties, followed by NERICA 11 and14 respectively. Thus, NERICA varieties had the best performance in most of the parameters that were measured. Therefore, these varieties can thus be used by breeders to develop varieties adapted to areas with limited rain fall and insufficient soil moisture for rice production.
干旱胁迫是旱作水稻种植区在旱作条件下面临的主要问题。它影响植物的生长发育,并最终导致相当大的产量下降。本研究旨在探讨干旱胁迫持续时间对旱稻品种生长特性和产量构成的影响。这项试验是在埃尔多雷特大学进行的,研究中使用了从肯尼亚和利比里亚获得的16个旱地商业和当地水稻品种。在温室中对水稻分蘖期和开花期进行了干旱胁迫处理。试验采用完全随机设计(CRD), 5个处理,重复3次。叶片卷曲、株高、开花至50%天数、成熟天数、穗数、小穗不育性、生物产量、叶片相对含水量、千粒重、收获指数和籽粒产量在不同处理(p≤0.001)和品种(p≤0.05)之间存在显著差异。与对照相比,处理对16个品种均有显著影响。水稻品种MWUR、杜拉多、L-22、Komboka、Jaowo、LAC-23、Kpatawee、MWUR、白米和红优莫受水分胁迫处理在滚叶、开花期和成熟期的影响显著,而水稻品种NERICA 1、2、3、4、10、11和14在分蘖期和开花期的影响显著。结果表明,土壤水分胁迫处理对NERICA 1、2、3、4、10的影响较小,其次是NERICA 11和14。因此,NERICA品种在大多数测量参数中表现最好。因此,育种者可以利用这些品种来培育适应降雨量有限和土壤水分不足地区的品种,以生产水稻。

A field trials was carried out at Shandaweel Research Station, Sohag Governorate, Agricultural Research Center, Egypt during the 2020/2021 and 2021/2022 seasons to study the influence of intercropping sugar beet with fahl berseem using three different nitrogen fertilization rates on yield, its components, and economic returns. The experiment was laid out in a randomized complete block design using a split-plot arrangement of three replicates. Three nitrogen fertilizer levels (165, 190, and 215 kg N/ha) were assigned to the main plots. while the sub-plots were allocated to five intercropping systems 100% sugar beet + three seeding rates of fahl berseem (15, 25, and 35% of its recommended rate of 48 kg/ha), sole sugar beet, and sole fahl berseem. The results revealed that most of the values of sugar beet traits significantly (P<0.05) decreased by increasing the percentage of fahl berseem seeding rates. whereas, a reverse trend was found in increasing nitrogen fertilizer levels. All traits of fahl berseem significantly (P<0.05) increased by increasing the percentage of fahl berseem seeding rates when intercropped with sugar beet and increasing nitrogen fertilizer level. The intercropping system IS3 (100% sugar beet + 35% fahl berseem) and fertilized plants with 165 kg N/ha recorded the highest land equivalent ratio (1.30). On the other hand, the intercropping systems IS1 (100% sugar beet + 15% fahl berseem) and 165 kg N/ha recorded the lowest land equivalent ratio (1.20). Fahl berseem was the dominant crop, whereas sugar beet was the dominated. The highest gross returns (3398 US$/ha) resulted from intercropping system IS3 (100% sugar beet + 35% fahl berseem) and 215 Kg N/ha. The lowest gross returns (2953 US$/ha) were obtained from intercropping systems IS1 (100% sugar beet + 15% fahl berseem) with 165 kg N/ha as average in both seasons. Hence it, to achieve higher gross returns preferred use intercropping system of 35% fahl berseem and 100% sugar beet with application of 215 Kg N/ha.
本研究于2020/2021和2021/2022年在埃及Sohag省农业研究中心shanaweel研究站进行了田间试验,研究了3种不同施氮量对甜菜间作产量、产量组成和经济效益的影响。试验采用完全随机区组设计,采用3个重复的分块法。施用3个氮肥水平(165、190和215 kg N/ hm2)。子田分为5种间作制度,100%甜菜+三种播种率,分别为甜菜推荐播种率的15%、25%和35%(48公斤/公顷)、单甜菜和单甜菜。结果表明,随着播苗率的增加,甜菜的大部分性状值显著(P<0.05)降低。而氮肥施量的增加则呈现相反的趋势。间作甜菜和增加氮肥施用量和增加黑麦的播率显著提高了黑麦的各项性状(P<0.05)。IS3(100%甜菜+ 35%甜菜碱)间作系统与施肥165 kg N/ha的植株的土地当量比最高(1.30)。另一方面,IS1(100%甜菜+ 15%甜菜碱)和165 kg N/ha的间作系统的土地当量比最低(1.20)。甜菜是主要作物,而甜菜是主要作物。最高的总收益(3398美元/公顷)来自于间作系统IS3(100%甜菜+ 35%小麦)和215公斤氮肥/公顷。两个季节平均氮量为165公斤/公顷的间作系统IS1(100%甜菜+ 15%甜菜)的总收益最低(2953美元/公顷)。因此,为了获得更高的总收益,最好采用35%的甜菜和100%的甜菜间作制度,施用215公斤氮/公顷。

The modern world agricultural sector has come under severe attack from several factors. These factors range from biotic to abiotic factors and they present threats to the environment and the world economies at large. If agricultural production is made more sustainable, it can be able to combat the current food shortages. Looking into the present scenario, there is a great need to improve the traditional breeding designing methods to develop genotypes of different crops that would be able to withstand the current adverse effects brought about by persistent climate change. Central to the basis and key factor of improving the designing methods in crop production are different digital technologies such as Artificial Intelligence (AI), Deep Learning (DL), Machine Learning (ML), Geographical Information System (GIS), Precision Agriculture (PA), and Remote Sensing (RS).  The digitalization of traditional breeding strategies has its weaknesses in terms of genetic gains it could offer in improving crop production. However, improving digital technologies would result in improved designing methods of crop production that would consequently result in increasing agricultural production and productivity. Therefore, the current review highlights the gains that have been made especially by AI and ML in designing methods of crop production. In addition, the review also highlights the limitations of these digital tools and their potential in crop designing methods for future crop genetic gains and production as well.
现代世界农业部门受到几个因素的严重打击。这些因素从生物因素到非生物因素都有,它们对环境和整个世界经济构成威胁。如果农业生产更具可持续性,就能够解决目前的粮食短缺问题。考虑到目前的情况,非常需要改进传统的育种设计方法,以开发能够承受当前持续气候变化带来的不利影响的不同作物的基因型。改善作物生产设计方法的核心基础和关键因素是不同的数字技术,如人工智能(AI),深度学习(DL),机器学习(ML),地理信息系统(GIS),精准农业(PA)和遥感(RS)。传统育种策略的数字化在提高作物产量方面可能提供的遗传收益方面存在弱点。然而,数字技术的改进将导致作物生产设计方法的改进,从而提高农业产量和生产力。因此,当前的综述强调了人工智能和机器学习在设计作物生产方法方面取得的进展。此外,该综述还强调了这些数字工具的局限性以及它们在作物设计方法中用于未来作物遗传增益和生产的潜力。

As organic farming gains popularity worldwide, it is crucial to investigate the potential benefits of using poultry manure as an organic fertilizer source. This study aimed to assess the comparative performance of tomato cultivation under organic and conventional farming practices, with a specific focus on the effects of varying rates of poultry manure applications. The research was carried out at the Teaching and Research Farm of College of Agriculture Science and Technology Jalingo, Taraba State, Nigeria. This was conducted during the 2021 cropping season (April - June) with four levels of poultry manure. Three (3) application rate of poultry manure (5.0 tha-1, 8.0 tha-1, and 11 tha-1) was used to compare with the control/check with no application of poultry manure, all replicated four times in a randomized complete block design. The objective of this research was to determine the impact of different rates of poultry manure application on tomato growth and yield potentials. After a thorough evaluation of the experimental plots, it was found that the treatment with 11tha-1 of poultry manure demonstrated superior performance compared to the other treatment levels. The tomatoes grown with this application rate exhibited significantly higher yields and improved plant vigor, as confirmed by the recorded data. The study's findings provide valuable insights for local farmers, as this research supports the use of 11 tha-1 poultry manure application as an effective strategy to enhance tomato cultivation and maximize yield potential. The necessity of conducting this research arises from the need to optimize tomato cultivation practices and address the growing demand for sustainable and environmentally friendly farming methods. The study also provides evidence that the application of 11 tha-1 poultry manure significantly improves tomato cultivation outcomes. The results obtained underline the relevance of optimizing nutrient management practices in organic and conventional farming systems, fostering enhanced yield potential, and promoting sustainable agricultural practices for future food security.
随着有机农业在世界范围内的普及,研究使用家禽粪便作为有机肥料来源的潜在好处是至关重要的。本研究旨在评估有机和传统耕作方式下番茄种植的比较表现,并特别关注不同禽粪施用量的影响。这项研究是在尼日利亚塔拉巴州贾林戈农业科技学院的教学和研究农场进行的。该试验在2021年种植季节(4月至6月)进行,使用了四种水平的禽粪。采用3种禽粪施用量(5.0 tha-1、8.0 tha-1和11 tha-1)与不施用禽粪的对照/对照进行比较,均采用随机完全区组设计重复4次。本研究的目的是确定不同家禽肥施用量对番茄生长和产量潜力的影响。在对试验田进行全面评价后,发现11ha -1家禽粪处理效果优于其他处理水平。记录资料证实,施此剂量的番茄产量显著提高,植株活力显著增强。这项研究的发现为当地农民提供了有价值的见解,因为这项研究支持使用11ha -1禽粪作为提高番茄种植和最大化产量潜力的有效策略。开展这项研究的必要性源于优化番茄种植实践的需要,以及解决对可持续和环境友好型耕作方法日益增长的需求。该研究还提供证据表明,施用11tha -1禽粪可显著提高番茄栽培效果。所获得的结果强调了优化有机和传统农业系统中养分管理实践、促进提高产量潜力和促进可持续农业实践对未来粮食安全的重要性。

Soil microbes are involved in many important ecosystem processes including nutrient acquisition, biogeochemical cycling and soil aggregation. Soil microbial diversity affects the soil belowground dynamics and fate of carbon and nutrients. Soil microbes are important for agricultural and plant production systems, hence understanding the effects of agroforestry systems on the soil microbes, is necessary in order to improve on soil health and fertility. The objective of the study was to determine the soil microbial biomass, microbial populations and microbial diversity in maize-banana based agroforestry system. The study was conducted at Kenya Agricultural and Livestock Research Organization farm in Kisii County. The experiment was laid out in a randomized complete block design with maize and banana intercropped with agroforestry trees. The treatments were; Maize, banana (MMBB), Maize-banana, Calliandra (MBCC), Maize (MM), banana (BB), Maize-banana, Leucaena (MBLL), Maize-banana, Sesbania (MBSS) and Maize, fertilizer (MMF). Soil samples were   collected from the agroforestry fields using a soil auger. Soil microbial biomass was measured using the chloroform fumigation extraction. Fungi and bacteria were enumerated by serial dilution plate method.Shannon diversity index (H’) and Simpson diversity index (1 - D) were used for the calculation of species diversity. SAS (version 9) statistical software was used for analysis. The treatments with agroforestry tree species had significantly higher soil microbial biomass (MBSS-86.33, MBCC-52.66 and MBLL- 47.0MgC/Kg) populations of bacteria (MBSS-197, MBCC-128.0 and MBLL-111.25x108cfu g-1soil) and fungi (MBSS-50.83, MBCC-29.167 and MBLL-14.0x105cfu g-1 soil) and diversity of bacteria (MBSS- (H' =1.61, D = 1), MBCC- (H' =1.04, D = 0.83), MBLL (H' = 0.52, D = 0.5) and fungi MBSS (H' =1.39, D = 1) MBCC (H' =1.04, D= 0.83), MBLL (H' =1.56, D = 0.93). MBSS increased microbial biomass, microbial populations and microbial diversity significantly an indication of improved soil health and hence recommended for adoption by farmers.
土壤微生物参与了养分获取、生物地球化学循环和土壤聚集等重要的生态系统过程。土壤微生物多样性影响土壤地下动态和碳和养分的命运。土壤微生物对农业和植物生产系统至关重要,因此了解农林业系统对土壤微生物的影响对于改善土壤健康和肥力是必要的。本研究旨在测定玉米-香蕉复合农林业系统土壤微生物量、微生物数量和微生物多样性。这项研究是在肯尼亚农业和牲畜研究组织位于Kisii县的农场进行的。试验采用完全随机区组设计,玉米和香蕉间作农林业树木。治疗方法是;玉米-香蕉(MMBB)、玉米-香蕉、花椒(MBCC)、玉米(MM) -香蕉(BB)、玉米-香蕉、银柳(MBLL)、玉米-香蕉、田葵(MBSS)和玉米-肥料(MMF)。土壤样品是用土壤螺旋钻从农林业田采集的。采用氯仿熏蒸法测定土壤微生物生物量。用串联稀释板法对真菌和细菌进行计数。采用Shannon多样性指数(H ')和Simpson多样性指数(1 - D)计算物种多样性。采用SAS (version 9)统计软件进行分析。土壤微生物生物量(MBSS-86.33、MBCC-52.66和MBLL- 47.0MgC/Kg)显著高于土壤细菌(MBSS-197、MBCC-128.0和MBLL-111.25 × 108cfu -1土壤)和真菌(MBSS-50.83、MBCC-29.167和MBLL-14.0x105cfu -1土壤),细菌多样性(MBSS- (H' =1.61, D= 1)、MBCC- (H' =1.04, D= 0.83)、MBLL (H' = 0.52, D= 0.5)和真菌MBSS (H' =1.39, D= 1)、MBCC (H' =1.04, D= 0.83)、MBLL (H' =1.56, D= 0.93)显著高于土壤微生物(MBSS-86.33、MBCC-52.66和MBLL- 47.0MgC/Kg土壤)。MBSS显著增加了微生物生物量、微生物种群和微生物多样性,这表明土壤健康得到改善,因此建议农民采用。

SAS (version 9) statistical software was used for analysis. The treatments with agroforestry tree species had significantly higher soil microbial biomass (MBSS-86.33, MBCC-52.66 and MBLL- 47.0MgC/Kg) populations of bacteria (MBSS-197, MBCC-128.0 and MBLL-111.25x108cfu g-1soil) and fungi (MBSS-50.83, MBCC-29.167 and MBLL-14.0x105cfu g-1 soil) and diversity of bacteria (MBSS- (H' =1.61, D = 1), MBCC- (H' =1.04, D = 0.83), MBLL (H' = 0.52, D = 0.5) and fungi MBSS (H' =1.39, D = 1) MBCC (H' =1.04, D= 0.83), MBLL (H' =1.56, D = 0.93). MBSS increased microbial biomass, microbial populations and microbial diversity significantly an indication of improved soil health and hence recommended for adoption by farmers.","PeriodicalId":415976,"journal":{"name":"Asian Journal of Research in Crop Science","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127527398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tridax procumbens and Ageratum conyzoides are two plant species commonly found in tropical regions and have been used in traditional medicine for various purposes. Field surveys were conducted in selected sites across Nnamdi Azikiwe University, Awka, Nigeria to assess the distribution and abundance of the two species. Data on soil moisture, light intensity, temperature, and altitude were also collected to determine the ecological factors that influence their growth and distribution. Phytochemically, the main constituents present in these plants using various techniques including chromatography and spectroscopy were isolated and identified. Results showed that the two plants have different ecological niches and exhibit varying levels of phytochemical diversity. Both plants were found to contain compounds such as flavonoids, alkaloids, and terpenoids, which may have potential medicinal properties. The leaves of Tridax procumbens and Ageratum conizoides were used for this study, and it was evaluated and compared for total saponin, total flavonoids and other secondary metabolites using standard procedures. The study of two different samples from the two plant species revealed the presence of saponin, tannin, alkaloid, flavonoid, steroid. The dried sample of Tridax gave a higher composition of saponin (1.85±0.03 mg/100g), flavonoids (1.34±0.03 mg/100g), tannin (2.51±0.02 mg/100g), alkaloids (1.49±0.02 mg/100g) and steroid (0.26±0.02 mg/100g), while the dry sample of Ageratum gave a composition of (1.68±0.03 mg/100g) of total saponins, (1.95±0.03 mg/100g) of total flavonoids, (0.06±0.02 mg/100g) of total phenol, (2.14±0.02 mg/100g) of alkaloids, (0.26±0.02 mg/100g) of total Terpenoid. There is significant difference between the phytochemicals seen in the two samples. Thus, this reveals that Tridax plant has more tannin which is used medicinally to lower total cholesterol and lower blood pressure, while Ageratum plant contains more saponins which is used medicinally to decrease blood lipids and lower cancer risks.
原藜和翘叶叠柱是热带地区常见的两种植物,在传统医学中有多种用途。在尼日利亚Awka的Nnamdi Azikiwe大学的选定地点进行了实地调查,以评估这两个物种的分布和丰度。收集了土壤湿度、光照强度、温度和海拔等数据,以确定影响其生长和分布的生态因子。在植物化学方面,利用色谱和光谱学等多种技术对这些植物的主要成分进行了分离鉴定。结果表明,两种植物具有不同的生态位和不同程度的植物化学多样性。这两种植物都含有类黄酮、生物碱和萜类化合物,可能具有潜在的药用价值。以原甘竹叶和灰隼叶为研究对象,采用标准方法对其总皂苷、总黄酮等次生代谢产物进行评价和比较。对两种植物的不同样品进行了研究,发现其中含有皂苷、单宁、生物碱、类黄酮和类固醇。三叶草干燥后的总皂苷(1.85±0.03 mg/100g)、总黄酮(1.34±0.03 mg/100g)、单宁(2.51±0.02 mg/100g)、生物碱(1.49±0.02 mg/100g)和甾体(0.26±0.02 mg/100g)含量较高,而Ageratum干燥后的总皂苷(1.68±0.03 mg/100g)、总黄酮(1.95±0.03 mg/100g)、总酚(0.06±0.02 mg/100g)、生物碱(2.14±0.02 mg/100g)、总萜(0.26±0.02 mg/100g)含量较高。在两个样品中所见的植物化学物质有显著差异。因此,这表明三叶草含有更多的单宁,可以用于降低总胆固醇和降低血压,而Ageratum含有更多的皂苷,可以用于降低血脂和降低癌症风险。

Yams are increasingly recognized for their good health benefits as people increasingly focus on healthy eating and wholesome eating. However, the high cost of yam cultivation and harvesting, as well as the limited level of mechanization, severely restricted the development of the industry. For this deep rhizomatous, brittle, and breakable yam crop, mechanized harvesting is prone to breakage, skin breakage, and low damage rates to the intact crop. In this paper, we have analyzed the characteristics of yam, the current situation of the yam economy in China, the development of mechanized techniques for yam harvesting at home and abroad, and the constraints. In addition, the development of casing yam cultivation techniques and mechanization of harvest is also promising. It mainly introduced plowshare furrow openers, disc furrow openers, spiral furrow openers and chain furrow openers, double-row chain yam planting and harvesting machines, spiral yam harvesting and planting machines, fully hydraulically suspended single-row yam harvesters and vibrating yam harvesters.
随着人们越来越关注健康饮食,山药对健康的益处也越来越得到认可。然而,山药种植和收获的高成本以及有限的机械化水平严重制约了该行业的发展。对于这种根状深、脆、易碎的山药作物,机械化收割容易破损、表皮破损,对完整作物的损伤率低。本文分析了山药的特点、中国山药经济的现状、国内外山药机械化采收技术的发展及其制约因素。此外,包衣薯蓣栽培技术和收获机械化的发展也很有前景。主要介绍犁铧开沟机、盘式开沟机、螺旋开沟机、链式开沟机、双排链式薯蓣种植收获机、螺旋式薯蓣收获种植机、全液压悬挂式单排薯蓣收获机、振动式薯蓣收获机。

Isabgol: Package Practices for Cultivation 伊莎戈尔:耕作的包装实践
Pub Date : 2023-07-20 DOI: 10.9734/ajrcs/2023/v8i4201
Suhel Eraqui, Mohammad Faizan Husain
Isabgol is a short-stemmed annual herb that grows up to 40 cm tall. A large number of flowering shoots emerge from the plant's base. The word isabgol derives from the Persian words "isap" and "ghol," which mean horse ear and describe the shape of the seed. Psyllium, which derives from the Greek word for a flea, refers to the size, shape, and whitish color of the seed, which is the most commercially important part of this plant. The seeds are encased in capsules that open when they reach maturity. The husk of the seed is thin, boat-shaped, white, translucent, odourless, and has a mucilaginous taste. The root system is well developed, with a well-developed tap root and a few fibrous secondary roots. Isabgol is widely grown in many parts of the world. It is native to the Mediterranean region and West Asia, reaching as far north as Sutlej and Sindh in Pakistan. It is also found in the Canary Islands, Southern Spain, North Africa, the Middle East, and North-Western Asia. It has been introduced and cultivated in North Gujarat, as well as adjoining parts of Western Rajasthan and Madhya Pradesh in India. However, the crop is spreading in previously unexplored areas of the country such as Punjab, Haryana, Uttar Pradesh, and Karnataka.   
伊莎贝尔是一种短茎一年生草本植物,可长到40厘米高。大量开花的嫩枝从植物基部长出来。“isabgol”这个词来源于波斯语“isap”和“ghol”,意思是马耳朵,描述了种子的形状。车前草(Psyllium)这个词源于希腊语中的跳蚤,指的是车前草种子的大小、形状和白色,而车前草种子是这种植物最具商业价值的部分。种子被包裹在蒴果中,成熟后会打开。种子的外壳薄,船形,白色,半透明,无味,并有粘液的味道。根系发育良好,有发达的直根和少量纤维状次生根。伊莎贝尔在世界许多地方广泛种植。它原产于地中海地区和西亚,北至巴基斯坦的萨特莱吉和信德省。在加那利群岛、西班牙南部、北非、中东和亚洲西北部也有发现。它已被引进和种植在古吉拉特邦北部,以及印度拉贾斯坦邦西部和中央邦的邻近地区。然而,这种作物正在该国以前未开发的地区蔓延,如旁遮普邦、哈里亚纳邦、北方邦和卡纳塔克邦。

Faba bean is an important pulse crop in Ethiopia; however its productivity is low due to lack of biotic and abiotic stresses tolerant varieties. The presence of genetic variability in the germplasm is important for the improvement of yield and other traits. Thus, this study was conducted to understand the extent of genetic variability and association for yield and yield related traits among existing faba bean genotypes. Fiftyfour genotypes were evaluated at two locations (Kulumsaand Asasa) using 9 x 6 alpha lattice design with two replications in 2022/23. The combined/pooled/ analysis of variance revealed that highly significant at (P≤0.01) and significant (P≤0.05) differences were observed among genotypes for all the traits. The phenotypic variance were higher than the genotypic variance of the traits, implies that the influence of the environment on the expression of traits. The genotypic coefficient of variation ranged from 1.89% for days to maturity to 16.14% for thousand seed weight and the phenotypic coefficient of variance value ranged from 2.49% for days to maturity to 17% for thousand seed weight. High estimate of heritability were recorded from days to 50% flowering, rust and thousand seed weight. High genetic advance were observed from thousand seeds weight and rust. Highest estimate of heritability with high genetic advance were observed from thousand seeds weight and rust. Seed yield had negative and highly significant correlation with days to maturity and rust at both genotypic and phenotypic levels, respectively. The genotypic path analysis showed that number of pod per plant exerted positive direct effect on seed yield followed by thousand seed weight, plant height and number of seeds per pod. The observed variations indicate the possibility for further improvement of grain yield and associated traits of faba bean genotypes by utilizing selected parental genotypes and targeted crossing schemes in breeding programs.
蚕豆是埃塞俄比亚重要的豆类作物;然而,由于缺乏生物和非生物抗逆性品种,其生产力较低。种质中遗传变异的存在对提高产量和其他性状具有重要意义。因此,本研究旨在了解现有蚕豆基因型之间的遗传变异程度以及产量和产量相关性状的关联。采用9 × 6 α晶格设计,于2022/23年度在两个地点(kulumsaa和Asasa)对54个基因型进行了评估。综合/汇总/方差分析显示,各性状在基因型间差异极显著(P≤0.01)和显著(P≤0.05)。性状的表型变异高于基因型变异,说明环境对性状表达的影响较大。基因型变异系数为1.89% ~ 16.14%(千粒重),表型变异系数为2.49% ~ 17%(千粒重)。从开花天数到50%,锈病和千粒重均有较高的遗传率。千粒重和锈病遗传进展明显。千粒重和锈病的遗传率最高,遗传进步大。籽粒产量在基因型和表型水平上分别与早熟天数和锈病呈极显著负相关。基因型通径分析表明,单株荚果数对种子产量有直接正向影响,其次是千粒重、株高和单株荚果数。观察到的变异表明,在育种计划中,通过选择亲本基因型和定向杂交方案,可以进一步提高蚕豆基因型的产量和相关性状。
