Pub Date : 2023-07-01 DOI: 10.21608/ejar.2023.189256.1362
The study was designed to investigate rural women’s involvement in food and agriculture businesses in Yobe State, Nigeria. Specifically, the research identified key agricultural interventions involving women, the viability of agribusiness, and constraints faced by rural women in the study area. Descriptive statistics, household and financial analysis, and principal component analysis (PCA) were used for data analysis. The study found that the Fadama Develeopment Programme was the most frequently reported (29%) and most effective intervention. Agribusinesses run by women were not only viable but also profitable. It recorded an average gross margin ratio (GMR) and return on investment (ROI) of 0.67 and 1.40, respectively. Ho wever, the achievements have met critical challenges such as a lack of women’s inclusion, security threats in the region, cultural barriers, and a lack of awareness. To this end, the study recommends maintaining women’s inclusion from program and intervention design to implementation. In addition, the security architecture of the region should be improved through local whistleblowers and cooperation. Finally, counselors should train and build the capacity of the local community, especially the women’s group .
该研究旨在调查尼日利亚约贝州农村妇女参与食品和农业企业的情况。具体而言,该研究确定了涉及妇女的主要农业干预措施、农业综合企业的可行性以及研究地区农村妇女面临的制约因素。采用描述性统计、家庭和财务分析、主成分分析(PCA)进行数据分析。研究发现,法达玛发展计划是最常被报道的(29%)和最有效的干预措施。由妇女经营的农业企业不仅可行,而且有利可图。平均毛利率(GMR)和投资回报率(ROI)分别为0.67和1.40。然而,这些成就也遇到了重大挑战,如缺乏妇女参与、该地区的安全威胁、文化障碍和缺乏认识。为此,该研究建议从方案和干预措施的设计到实施都保持妇女的参与。此外,应通过地方举报和合作,完善地区安全架构。最后,辅导员应培训和建设当地社区,特别是妇女团体的能力。

Pub Date : 2023-07-01 DOI: 10.21608/ejar.2023.193896.1349
A two-year study was conducted at Giza Research Station, Agricultural Research Center (ARC), Giza, Egypt during 2020/2021 and 2021/2022 seasons to evaluate the yield potential of twenty-five lupine genotypes and identify their morphological traits compared with cultivar Giza 1. Twenty six genotypes (75 B 15.17, 75 B 9.15, P 20950, Family 2, Family 4, Family 11, Family 12, Local 12, Local 20, Line 6, Line 15, Line 21, X1/90/72, Sakolta, Qena, Edfo, Isna 1, Isna2, Isna 6, Isna 7, Qous 1, Qous 3, Qous 4, Qous 5, Belbais 9 and Giza 1) were distributed in a randomized complete blocks design in three replications. Sixteen morphological traits were described using UPOV (The International Union for the Protection of New Varieties of Plant) Guidelines. The morphological characterization indicated that the short or medium growth habits of genotypes at the flower bud stage were absent, and very tall genotypes at the green repining stage were not observed. Also, violet, pink, light yellow, and dark yellow flower wings, as well as late or very late maturing genotypes were absent. Moreover, stem anthocyanin coloration and the leaf green color at the flower bud stage, as well as the density of seed ornamentation were observed in all genotypes. The combined analysis of variance showed that lupine genotypes differed significantly for all the studied traits. Meanwhile, seasonal effects and their interactions were not significant for all the studied traits. Genotypes Qous 5 and P 20950 had a higher number of branches and pods per plant. Meanwhile, genotypes Qous 3 and Qous 5 had a higher number of seeds per plant and 100-seed weight. GT-biplot analysis revealed that Qous 4, Belbais 9, Family 2, P 20950, Qous 5, Qous 3 and Qous 1 are considered the most desirable genotypes for yield traits. In addition to, cluster (C) that contains nine genotypes (Family 2, Qous 5, Family 4, Edfo, Isna 6, Isna 2, Belbais 9, Qous 4 and Giza 1) surpassed the other genotypes in seed yield per plant. Concerning on high-yielding genotypes per unit area, Qous 3 and Qous 5 can be promising genotypes for selection criteria to increase lupine productivity. On the basis of previous information and relationships identified, genotypes Qous 4, Belbais 9, Family 2 and Qous 5 can be distinguished for lupine development and preparation future breeding programs in Egypt.
在2020/2021和2021/2022两季,在埃及吉萨农业研究中心(ARC)吉萨研究站进行了为期两年的研究,以评估25个羽扇豆基因型的产量潜力,并比较其与吉萨1号品种的形态特征。26个基因型(75b15.17、75b9.15、p20950、Family 2、Family 4、Family 11、Family 12、Local 12、Local 20、Line 6、Line 15、Line 21、X1/90/72、Sakolta、Qena、Edfo、Isna 1、Isna2、Isna 6、Isna 7、Qous 1、Qous 3、Qous 4、Qous 5、Belbais 9和Giza 1)采用完全随机区组设计,分成3个重复。采用UPOV(国际植物新品种保护联盟)指南对16个形态性状进行了描述。形态特征表明,花芽期基因型的短、中长势不存在,绿穗期基因型的高长势不存在。此外,紫色、粉红色、淡黄色和暗黄色的花翅以及成熟较晚或很晚的基因型也不存在。各基因型的茎花青素着色、花蕾期叶绿着色、种子纹饰密度均有显著差异。综合方差分析表明,羽扇豆各性状的基因型差异显著。同时,季节效应及其相互作用不显著。基因型qou5和p20950单株分枝数和荚果数较高。基因型qou3和qou5单株种子数和百粒重较高。gt双图分析显示,qou4、Belbais 9、Family 2、p20950、qou5、qou3和qou1被认为是产量性状最理想的基因型。此外,包含9个基因型(Family 2、Qous 5、Family 4、Edfo、Isna 6、Isna 2、Belbais 9、Qous 4和Giza 1)的聚类(C)单株种子产量超过其他基因型。在单位面积高产基因型方面,qq3和qq5可以作为提高羽扇豆产量的选择标准。根据已有的信息和鉴定的关系,可以区分qous4、Belbais 9、Family 2和qous5基因型,为埃及羽扇豆的发育和未来育种计划做准备。

Accelerating rice breeding can be accomplished through various approaches, including molecular or conventional techniques. In this regard, some rice breeding programs around the world have changed to use rapid generation advancement (RGA) as a new breeding method. The objectives of this investigation are to establish and implement RGA techniques at the Rice Research & Training Center (RRTC) to develop new, improved, blast disease-resistant, and high-yielding varieties more quickly and at a low cost. Three F 2 populations, (Giza177 x Sakha Super300), (IR75589-31 x Giza178), and (Giza179 x IR59673-93-2-3-3-2), were advanced to F 2 and evaluated in Lines Stage Trials (LST) and preliminary yield trials (PYT). RGA facilities were installed at the greenhouse of the RRTC, and the F 2 plants of each population were harvested individually. One seed from each panicle was used to cultivate the next generation (F 3 ) according to the single seed descent (SSD) method. The RGA technique was successfully implemented at RRTC with simple multipot trays and the maintenance of the greenhouse and screen house. The early generations (F 2 , F 3 , F 4 , and F 5 ) showed good performance in the greenhouse; the narrow space and low fertilizer led to early flowering. promising RGA lines, SK-RGA2-5, SK-RGA2-9, and SK-RGA3-6, revealed grain yields of more than 11.0 t/ha compared with the check varieties, Giza177, Giza178, and Sakha super300, which gave 9.57, 10.17, and 10.50 t/ha, respectively. For grain quality traits, most of the test RGA lines and check varieties have low to medium amylose content, ranging between 17.83 and 23.13%. RGA lines and check varieties gave desirable values for hulling and milling. In general, hulling% ranged between 80.0 and 85.0%, and milling% ranged between 69.43 and 73.0%.
加速水稻育种可以通过各种方法完成,包括分子或传统技术。在这方面,世界上一些水稻育种计划已经将快速世代推进(RGA)作为一种新的育种方法。本研究的目的是在水稻研究与培训中心(RRTC)建立和实施RGA技术,以更快、更低的成本开发新的、改良的、抗稻瘟病的高产品种。3个f2群体(Giza177 × Sakha Super300)、(IR75589-31 × Giza178)和(Giza179 × IR59673-93-2-3-3-2)进入f2,并在株系阶段试验(LST)和初步产量试验(PYT)中进行评价。在农垦中心的温室内设置了农垦设施,每个种群的f2株分别收获。每穗取一粒种子,按单粒法培养下一代(f3)。RGA技术成功地在RRTC实施了简单的多盆托盘,并对温室和纱棚进行了维护。前代(f2、f3、f4、f5)在温室中表现良好;狭窄的空间和低施肥导致开花早。与对照品种吉泽177、吉泽178和萨哈super300相比,有潜力的RGA品系SK-RGA2-5、SK-RGA2-9和SK-RGA3-6的产量均超过11.0 t/ha,吉泽177、吉泽178和萨哈super300的产量分别为9.57、10.17和10.50 t/ha。在籽粒品质性状方面,大部分试验品系和检验品种直链淀粉含量为中低水平,在17.83 ~ 23.13%之间。RGA线和校核品种为脱壳和铣削提供了理想的值。脱壳率在80.0 ~ 85.0%之间,磨粉率在69.43 ~ 73.0%之间。

Improvement of restorer and maintainer lines in rice (Oryza sativa L.) by gamma radiation 伽玛辐射改良水稻恢复系和保持系的研究
Pub Date : 2023-06-23 DOI: 10.21608/ejar.2023.194132.1360
Rice is a strictly self-pollinating crop. However, in hybrid rice seed production, an effective male sterility system is used to produce hybrid seed in bulk. In a hybrid rice system, the pollen grains of cytoplasmic male sterile (CMS) lines are sterile, and the female organ of the CMS depends on the fertile pollen released by the maintainer or restorer lines via out-crossing or cross-pollination to produce seeds. Floral traits and growth behavior of CMS and its corresponding maintainer and restorer lines are essential factors in hybrid rice seed production because they influence outcrossing or cross-pollination. Seeds of the 4 maintainer lines, or B lines, and the 5 restorer lines were treated with five gamma radiation doses: 0, 100, 200, 300, and 400 Gy, to study their mutagenic effect on the growth, yield, and floral traits of these rice genotypes, as well as to induce genetic variability for selecting plants with desirable characters. Results showed that all growth, yield, and floral traits studied in the M1 generation decreased steadily with increasing doses of gamma rays when compared to the control. The dose of 300 Gy recorded the highest mean values for some growth, yield, and floral traits studied in the M2 generation when compared to the control. The genotype-dose interaction was significant and highly significant for all growth, yield, and floral traits studied in M1 and M2 segregating generations except for anther width in the M1 generation, which indicated that the tested genotypes varied from treatment to treatment. The highest values for growth and yield traits were recorded when using Giza 178, Giza 182, and the IR 58025B mutant with 300 Gy of gamma rays in the M2 segregating generation. And the highest values for floral traits were recorded when using Giza 182 and the IR 70368B mutant with 300 Gy of gamma rays in the M2 segregating generation. The measurements of variation were, in general, higher in the treated plants at M2 generation. High heritability coupled with high genetic advance as percent of the mean was recorded for most studied traits, suggesting the improvement of these characters through simple phenotypic selection. Used irradiation by gamma-ray exhibited different genetic variability for the development of restorer and maintainer lines, such as desirable plant height, early heading, and high yield plants. Also, improving floral traits such as the length and width of anthers, percentage of pollen fertility, number of pollen grains per anther, total stigma length, and stigma width
水稻是一种严格意义上的自花授粉作物。然而,在杂交水稻制种中,一种有效的雄性不育系统用于大批量生产杂交种子。在杂交水稻系统中,细胞质雄性不育系(CMS)的花粉粒是不育的,CMS的雌性器官依靠保持系或恢复系通过异交或异花授粉释放的可育花粉来产生种子。CMS及其相应的保持恢复系的花性状和生长行为影响着异交或异花授粉,是杂交水稻制种的重要因素。将4个保持系(B系)和5个恢复系的种子分别以0、100、200、300和400 Gy的γ辐射剂量处理,研究其对水稻基因型的生长、产量和花性状的诱变效应,并诱导遗传变异,以选择具有理想性状的植株。结果表明,与对照相比,随着γ射线剂量的增加,M1代的所有生长、产量和花性状均呈稳定下降趋势。与对照相比,300 Gy剂量对M2代的某些生长、产量和花性状的平均值最高。除M1代花药宽度外,M1和M2分离代的所有生长、产量和花性状的基因型-剂量互作均显著且极显著,表明不同处理的基因型存在差异。在M2分离代中,使用吉萨178、吉萨182和300 Gy γ射线的IR 58025B突变体的生长和产量性状最高。在M2分离代中,吉萨182和IR 70368B突变体在300 Gy γ射线照射下的花性状最高。总的来说,处理植株在M2代的变异测量值较高。大多数研究性状的遗传力高,遗传进阶率高,表明这些性状通过简单的表型选择得到了改善。伽玛射线辐照对恢复系和保持系的发育表现出不同的遗传变异,如理想株高、早抽穗和高产植株。此外,还改善了花药的长度和宽度、花粉育性百分比、每花药的花粉粒数、柱头总长度和柱头宽度等花性状

And the highest values for floral traits were recorded when using Giza 182 and the IR 70368B mutant with 300 Gy of gamma rays in the M2 segregating generation. The measurements of variation were, in general, higher in the treated plants at M2 generation. High heritability coupled with high genetic advance as percent of the mean was recorded for most studied traits, suggesting the improvement of these characters through simple phenotypic selection. Used irradiation by gamma-ray exhibited different genetic variability for the development of restorer and maintainer lines, such as desirable plant height, early heading, and high yield plants. Also, improving floral traits such as the length and width of anthers, percentage of pollen fertility, number of pollen grains per anther, total stigma length, and stigma width","PeriodicalId":11513,"journal":{"name":"Egyptian Journal of Agricultural Research","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82587823","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}
