“…Same finding were observed by Copur et al (2009) and Tayyar (2007). Haliloglu et al (2007) and Kumar et al (2019) also reported that seed yield showed positive correlation with days of flowering, plant height and number of grains per plant. The means comparison of genotypes, environment and their interaction is represented in Table 5, after combined analysis.…”

“…Similar result were found by Miladinovic et al (2006) varieties vary in their growing days, longer this duration higher will be the yield and vice versa. Arshad et al, (2006) and Kumar et al (2019) also reported significant correlation of grain yield with days to maturity, number of branches per plant and 100-seed weight. The highest number pods per plant in the years' means i.e.…”

Background: Soybean is a most important crop providing edible oil and plant protein source for human beings, in addition to animal feed because of high protein and oil content. This study was conducted to find out the suitability and the performance of 14 soybeans [Glycine max (L.) Merr.] varieties/advance lines in the growing seasons of two consecutive years 2017 and 2018.Methods: A randomized complete block design with four replications was used at research area of GAP Agricultural Research Institute, Sanliurfa, situated in Southeast region of Turkey. The data regarding different parameters including days taken to days taken to flower initiation (days), days taken to physiological maturity (days), growing degree days (days), plant height at harvest (cm), number of pods, 1000 grain weight (g), grain yield kg da-1), crude oil (%) and protein (%) were recorded during the course of study. Result: The variety Sa-88 and advance line KA08-03 were the highest grain yielders (3705 and 3660 kg/ha, respectively) among others. Though the qualitative characters were statistically significant but the difference was not much higher. Both the cultivar and line presented good yield making the results possible for rural extension to confirm the suitability of these genotypes to be used to support the ever-increasing demand of soybean meal and oil domestically.

Characterization of genotypes for various traits is a basic and very essential criterion for crop varietal improvement programmes. Under the present investigation fifty seven advanced breeding lines along with three best checks were evaluated to characterize 17 phenotypic and 11 yield attributing traits at JNKVV, Jabalpur. Morphological/phenotypic traits were described as per DUS guidelines. Yield attributing traits were utilized to work out various biometric parameters (Phenotypic Coefficient of Variation,(PCV), Genotypic Coefficient of Variation (GCV), heritability with genetic advance, correlation and path coefficient). Phenotypic characterization exhibited huge variability among advanced breeding genotypes for most of the descriptor traits. Semi-erect growth habit (100%), presence of peroxidase activity in ripe seed (100%), Semi-determinate growth type (95%), Yellow colour ripe seed testa (90%) and tawny colour pod hair (86.8%) were most common traits studied in genotypes. Significant variation was also obtained for yield attributing quantitative traits. PCV was higher in magnitude than GCV for all the traits and the highest for seed yield per plant (39.10 and 36.76, respectively). The highest heritability and genetic advance as per cent of mean were recorded for biological yield per plant and seed yield per plant, respectively. Seed yield per plant demonstrated a highly significant positive relation with biological yield (0.797**) followed by 100 seed weight (0.735**) and the number of pods per plant (0.620**). Whereas, it was negatively correlated with plant height (-0.303**). The genotypic path coefficient analysis also revealed that the highest positive direct effect on seed yield per plant was due to biological yield per plant followed by 100 seed weight.

“…The seed size illustrated by the weight of 100 seeds is an important factor in efforts to increase soybean production (Johnson et al 2001). Seed size has been known to be genetically inherited (Brian et al 2002;Kumar et al 2020) and has a positive direct effect on soybean yield (El-Badway and Mehasen, 2012).…”

Background: Knowledge about genetic parameters can help plant breeders to determine which selection criteria are beneficial. This study aims to estimate the genetic parameters of soybean seed characteristics.Methods: A total of 91 soybean lines from three different populations were evaluated during dry season in 2016. All genetic material used was grown following a randomized complete block design with two replicates. Soybean pods were harvested after 90% of the leaves had yellowed or fallen. The characteristics of the seeds observed included length, width, thickness and weight of 100 seeds.Result: The results showed that there were two seed shapes (round and ellipse) and two seed sizes (large and medium). There is a broad genetic variability of soybean seed characteristics. Heritability broad sense varies from 0.42 to 0.84, classified as moderate (length-width ratio) to high (length, width, thickness, length-thickness ratio, width-thickness ration and weight of 100 seeds). This therefore shows that there is an opportunity to improve the characters of soybean seeds. The length, width, thickness, ratio of the three characters and the weight of 100 seeds can be used as selection criteria in a soybean breeding program to obtain large-seeded soybeans with a round or elliptical shape.
