The genetic control of plant height – important trait associated with yield – is practically not studied in diploid wheats. In this paper, using reciprocal crosses between two Triticum monococcum accessions – var. monococcum (UA0300311) and var. nigricultum (UA0300282) in autumn and spring sowing, inheritance of the plant height is studied. The sowing period significantly affects the expression of einkorn plant height. Data from the generations P1, P2, F1, F2 were used for segregation analysis. For a combination of UA0300311 × UA0300282, the optimal models for plant height inheritance are: at autumn sowing – one main gene with a negative complete dominant effect, its additive effect is –8.05; at spring sowing – one main gene with an additive-dominant effect, its additive effect is –24.51. For the reciprocal combination UA0300282 × UA0300311, at autumn sowing, the optimal model of plant height was one main gene with an equal additive-dominant effect, it additive effect is 10.94; at spring sowing – one main gene with a negative complete dominant effect, its additive effect is –18.37. The heritability was in all cases from 96.52% to 99.70%. The high dispersion of the trait in the second hybrid generation suggests that the studied parental forms differ not only in the main gene, as follows from the results of segregation analysis, but also in the system of modifier genes with a weak effect.

In the study, 58 synthetic wheat lines and 6 bread wheat varieties were used as material. Synthetic wheat lines and bread wheat varieties were investigated for resistance to root rot under field conditions. In laboratory conditions, 1 ml (1x106 spores/ml) of root collar disease was inoculated into each tube at the junction of the stem of the plant and the soil, 1 week after seed sowing. In terms of root rot, which is one of the important problems in the Thrace region, it was determined that synthetic wheat lines showed resistance properties compared to bread wheats. While bread wheat varieties widely planted in the region do not show good tolerance in terms of resistance to root collar, synthetic bread wheat genotypes ZFSN 6, HRSN 11-14, HRSN 13-17 and HRSN 14-10, HRSN 6-8, HRSN 6-2, ZFSN 8 and ZFSN 3 genotypes showed superior properties in terms of resistance to root rot.

Limited water availability in future due to climate change may impact wheat yield and the food security. Therefore, it is necessary to find out the agronomic solutions to reduce the drought induce yield losses in wheat. Planting method affects wheat yield by changing the soil water status and root growth. This 2-year study was designed to evaluate the impact of various planting methods along-with water irrigation deficit regimes at different growth stages on wheat yield and net returns. The experiments were conducted in a randomized complete block design with three replications using two-way factorial arrangements. The experiment consisted of five planting methods (PM) viz. conventional broadcasting-PM, ridge-PM, bed-furrow-PM, gap-chat-PM and line-PM; and three water regimes viz., well-watered condition, mild and sever-terminal drought stress (TDS). The results revealed that wheat crop grown under bed-furrow-PM had better morphological growth under well-watered condition, and the crop grown under the same planting method performed better for morphological traits under mild-TDS and sever-TDS during both years. Irrometer Tensiometer was used to check the moisture stress level during terminal drought conditions. Better performance of wheat under mild-TDS and sever-TDS in bed-furrow-PM was the outcome of better antioxidants enzymatic and non-enzymatic activities which was later translated into better wheat yield and high net returns under water stress than other planting methods. In conclusion, bed-furrow-PM is the most suitable method for profitable wheat production in arid and semiarid region under water limited scenarios.

Heterosis is an effective way to increase yield and improve quality in alfalfa breeding. The key issue for efficiently use of heterosis is to identify parents having potential for producing hybrid combinations with higher performance. This study aimed to analyze genetic distance between the 48 alfalfa accessions, and combine different hybrid combinations. The results showed that the mating ability of the hybrid combination in which both parents are tetraploid is greater than that in which both parents are diploid or the hybrid combination with different parental ploidy. When the different ploidy levels of parents, the mating ability of alfalfa hybrid combination with diploid as female parent is better than that of alfalfa hybrid combination with tetraploid as female parent. he hybrid combination of diploid alfalfa as a female parent with tetraploid as a male parent is more heterosis than the hybrid combination of diploid as a male parent. Moreover, CYK2ｘHH10 with high heterosis and CYK4xHH10 with high the relative seed setting rate should be possible to breed high yielding hybrid, which could be used as candidate materials for further research.

One of the complex issue in the way of releasing new high-yielding and stable oilseed rape cultivars is genotype by environment interaction (GEI) which reduce selection efficiency. In the current study, parametric and non-parametric statistics as well as the AMMI model have been compared to identify the best stability models to clarify GEI complexity. The experiment has been conducted in the warm regions of Iran including; Gorgan, Sari, Zabol, and Hajiabad during two cropping seasons (2016-2017 and 2017-2018) for 16 genotypes in a randomized complete block design with three replications. The AMMI analysis of variance on grain yield showed the significant effects of genotype, environment, and the interaction effects of GEI on yield. Based on the AMMI ANOVA, the major contribution of GEI was captured by the first and second interaction principal component axes (IPCA1 and IPCA2) which explained 34.29% and 29.81% of GEI sum of the square, respectively. Additionally, Different parametric and non-parametric stability methods including; bi, S2di, CVi, W2i, σ2i, Pi, Si(1), Si(2), Si(3), Si(6), Npi(1), Npi(2), Npi(3), Npi(4), KR and TOP have also investigated. Based on AMMI, parametric, and non-parametric stability statistics, genotypes G2 (SRL-95-7) and G9 (SRL-95-16) were selected as the stable and high-yielding genotypes. Likewise, Principal component analysis based on rank correlation matrix enabled us to distinguish high-yielding genotypes to stable (high-yielding genotypes in various environments) and unstable (high-yielding genotypes in low-yielding environments) ones. Furthermore, a significant Spearman correlation was observed between yield mean and GSI, Pi, Si(3), Si(6), Npi(3), Npi(4), and KR. Therefore, different efficient strategies were identified in this study and since we looked up high-yielding and stable genotypes, G2 (SRL-95-7) and G9 (SRL-95-16) were finally selected.

Plant density can have a major impact on peanut (Arachis hypogaea L.) yield. Information is limited in the Eastern Mediterranean Transition Region of Turkiye on growth, development, and yield of peanut cultivars based on plant density. To address this limitation, the cultivars Aysehanim, Rigel, Halisbey, Masal, and NC 7 were established in a single row planting pattern consisting of rows spaced 70 cm apart with an inter-row plant distance of 15 cm (95.000 plants ha-1) versus a twin row planting pattern consisting of rows spaced 20 cm apart on 90 cm centers with an intra-row distance of 15 cm (148.000 plants ha-1). The interaction of cultivar × plant density was significant for most variables. Irrespective of cultivar, establishing a plant population of 148.000 plants ha-1 in the twin row planting pattern resulted in greater pod yield than the single row planting pattern with a plant density of 95.000 plants ha-1. Pod yield was similar for Rigel, Masal, and NC 7 in the twin row planting pattern and exceeded that of Aysehanim and Halisbey. Conversely, yield of Rigel and Halisbey was similar in the single row pattern and exceeded yield of Aysehanim and NC 7.

Atriplex nitens, which can grow in extreme ecological conditions and produce a high amount of forage material, has been seen as an important alternative forage source for livestock. With the present study, the effect of different sowing (mid-April, late-April, early-May, mid-May) and harvesting periods (end of vegetative period, beginning of flowering, full flowering period) on forage quality was tried to be determined. For this purpose, a study was planned according to randomized complete block design in split plots with three replications in Iğdır irrigated conditions in 2019 and 2020. As a result of the study, the forage quality values of the stem, leaf and whole plant differed according to the sowing and harvesting periods. Accordingly, it was determined that the crude protein, dry matter digestible, disgestible energy, metabolic energy and relative feed value of the stem, leaf and whole plant increased as the sowing time was delayed, but neutral detergent fibre and acid detergent fibre ratios decreased. Similar results were obtained by moving harvests to an earlier time. As a result, it was determined that the stem, leaf and whole plant produced a low, very high and medium quality forage material in late sowing and early harvests, respectively.

The present research was undertaken to evaluate of soybean hybrids environmental interaction and adaptability on Mediterranean region conditions. Seven advanced (F7) soybean cross breeding lines (KB-67, KS-39, KS-14, KS-12, KS-11, KS-10, KS-2) selected from the Kunitz x SS-201 and Kunitz x Bert crosses populations based on earliness and yield characteristics in the preliminary trials and three soybean varieties (Bravo, Nova and Arisoy) were tested in the trial in four replications in 2017 and 2018 according to the randomized blocks trial design. The analysis of variance revealed significant variations for all characters. According to research findings the yield of lines and varieties 2017 and 2018 varied from 1008.38-1567.13 kg ha-1 and 1018.94-1367.00 kg ha-1 respectively and KS-39 advanced soybean line had the highest grain yield in terms of two years’ average. The highest plant height (95.55 cm) was obtained from KS 11 and the lowest plant height (78.80 cm) from BRAVO variety. According to the two-year average data, KB-67 (129.62 pods per plant) and KS-39 (114.70 pods per plant) lines were the genotypes with the highest number of pods in the plant. The number of flowering days varied between 32.50 days and 36.75 days according to the two-year averages, and the KS-12 genotype was the earliest flowering genotype. The lines KS-10 (103.38) and KS-12 (103.50) came to the fore as the genotypes with the earliest maturation days. Among the lines tested in the experiment, KS-11 in terms of plant height, KS-14 in terms of first pod height, KS-14 in terms of 100-seed weight, and KS-39 in terms of the number of seeds per pod were the lines that showed the best performance.

Among the lines tested in the experiment, KS-11 in terms of plant height, KS-14 in terms of first pod height, KS-14 in terms of 100-seed weight, and KS-39 in terms of the number of seeds per pod were the lines that showed the best performance.","PeriodicalId":23385,"journal":{"name":"Turkish Journal of Field Crops","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43287090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
This research was conducted to determine the effects of different nitrogen sources and rates on some warm-season turfgrasses under Mediterranean-type climate conditions in 2017-2018. The experimental design was a split-split plot with design with three replicates; turfgrass species as the main plot, nitrogen sources as the subplots, and nitrogen doses as the sub subplots. The main plots consist of four nitrogen sources: two slow-release fertilizers, one organomineral fertilizer, and one sewage sludge. Subplots consist of three warm-season turfgrass species; zoysiagrass (Zoysia japonica Steud.), hybrid Bermudagrass (Cynodon transvaalensis x Cynodon dactylon), seashore paspalum (Paspalum vaginatum Sw.), and one cool-season turfgrass species, tall fescue (Festuca arundinacea Schreb.). The nitrogen doses were as follows; 0.0, 2.0, 3.0 and 4.0 g m-2. Turf color and quality were evaluated visually monthly. Also, clipping weight is determined. According to the result, slow-release and organomineral fertilizers can be assessable as N sources that will meet the nutritional needs of the turfgrasses. Zoysiagrass and seashore paspalum showed almost equivalent scores and gave sufficiently dark turf color and quality. Turfgrass should be fertilized at least with 3.0 g m−2 N to provide acceptable turf color and quality.
本研究旨在确定2017-2018年地中海型气候条件下不同氮源和氮量对一些暖季草坪草的影响。实验设计为三个重复设计的分割地块；以草坪草种类为主，氮源为辅，氮剂量为辅。主要地块由四种氮源组成：两种缓释肥料、一种有机矿物肥料和一种污水污泥。亚地块由三种暖季草坪草组成；结缕草（Zoysia japonica Steud.）、杂交狗牙根（Cynodon transvalensis x Cynodon dactylon）、海滨雀鲷（paspalum vaginatum Sw.）和一种冷季草坪草高羊茅（Festuca arundinacea Schreb.）；0.0、2.0、3.0和4.0克m-2。草皮的颜色和质量每月进行一次视觉评估。此外，还确定了剪裁权重。结果表明，缓释有机矿物肥料可作为满足草坪草营养需求的氮源。结缕草和海滨雀鲷表现出几乎相同的分数，并且提供了足够深的草皮颜色和质量。草坪草应至少施肥3.0 g m−2 N，以提供可接受的草坪颜色和质量。

This research was carried out to evaluate the grain yield, yield traits and some quality characteristics of 18 bread wheat genotypes in seven different locations in Thrace region using principal component analysis and genotype + genotype × environment interaction (GGE) biplot analysis to determine the genotypes with high yield and desired quality characteristics during the 2016-2017 and 2017-2018 cropping years. The experiments were arranged in a randomized complete block design with four replications. Genotype, environment and genotype × environment interactions were found statistically significant at p≤0.01 level for all investigated traits. Mean values of the genotypes varied between 4841-6807 kg ha-1 for grain yield, 118.6-131.6 days for heading date, 80.4-104.7 cm for plant height, 7.7-10.4 cm for spike length, 16.4-20.3 for number of spikelets per spike, 16.4-20.3 number of grains per spike, 1.49-2.41 g grain weight per spike, 72-77.8 kg hl-1 for test weight and 36.6-45.3 g for thousand kernel weight. Principal component biplot analyzes explained the relationships between the investigated traits and genotypes at a ratio of 60.9%. It was observed that there was a positive and significant relationship between grain yield and test weight, a negative relationship with grain yield and spike length and grain weight per spike. GGE biplot analysis explained 82.65% of the relationship of genotype + genotype x environment for grain yield. According to the GGE biplot analysis two mega environments were determined and Lucilla and Glosa genotypes took place in the biggest mega environment consisted of four environments as superior genotypes.
