“…In the present study, high heritability (>70%) coupled with high genetic advance (>30%) were observed for harvest index followed by biological yield /plant, seed yield /plant, number of pods /plant and 100-seed weight indicating the predominance of additive gene action in the inheritance of these characters. Similar results were observed by Patil et al (2011), Reni and Rao (2013), Chavan et al (2014) Chandrawat et al (2017 and Jain et al (2017). While studying the correlation coefficients, it was observed that the genotypic correlation coefficients were higher than their corresponding phenotypic ones for most of the traits studied indicating an inherent association among the various characters under study (Table 2).…”

The present investigation was undertaken to assess the genetic variability and character associations for seed yield and component characters in 307 soybean germplasm lines. The lines were raised in augmented block design in four blocks during kharif 2014. Out of these, twenty seven promising genotypes were selected and forwarded for evaluation along with four checks in randomized block design with three replications at CSKHPKV, Palampur (H.P) during kharif 2015. The analysis of variance revealed the presence of sufficient genetic variability in the breeding material. High PCV and moderate GCV were recorded for harvest index and biological yield/plant. High heritability coupled with high genetic advance were observed for harvest index followed by biological yield /plant, seed yield /plant, number of pods/plant and 100-seed weight indicating the predominance of additive gene action in controlling the trait. Number of branches /plant, number of seeds /pod, biological yield/plant and harvest index exhibited significantly positive correlation with seed yield /plant both at phenotypic and genotypic levels. Two traits viz., harvest index and biological yield /plant could be considered as direct selection indices for yield improvement in soybean.

“…These referred that the included cultivars would be good material in future breeding researches for the development of those characters and yield. Same result was found by Chandrawat et al (2017) in soybean. The year (Y) variations (in respective four years) were found to be highly significant for number of flower per plant and number of pod per plant, and average number of seed per pod and average pod weight (g) were non-significant.…”

“…Upadhyay and Mehta (2010) found high heritability in some traits in dolichos bean. Chandrawat et al (2017) also obtained high heritabilities and high genetic advance in soybean in pods per plant and 100 seed weight. Mazid et al (1982) studied black gram and found highest genetic advance and genetic advance in percentage of mean for the number of pods per plant and suggested that direct selection for the character would be effective for the improvement of yield.…”

Eleven genotypes of lablab bean were put into trial in four consecutive years to evaluate genetic variability among characters. Genotypic and phenotypic coefficient of variability, heritability and genetic advance as percent of mean were estimated for four yield contributing characters i.e. number of flowers per plant, number of pods per plant, average number of seed per pod and average pod weight (gm). The range of variation was highly pronounced in all the four characters. Without grouping the presence of wide range of variation in these characters indicate that they are quantitative in nature and are under polygenic in control. Mean with standard error showed differences between the varieties and co-efficient of variability in percentage (CV%) indicates certain degree of variability for the characters studied which are prerequisite in breeding research. Genotypes were found to be significantly different for all characters in analysis of variance. Low differences between PVC and GVC shows that these traits are less influenced by environment and the effect of heritable components were high. High heritability coupled with high genetic advance as percent of mean was recorded by number of flowers per plant, number of pods per plant and average pod weight (g) indicates additive action of genes controlling them.

“…The pooled analysis of variance revealed that mean squares due to genotypes were significant for all the traits indicating varietal differences for all the characters studied (Table 1). Earlier, significant variability was also reported by Khurana and Sandhu (1972), Shwe et al (1972) and Chandrawat et al (2017). Years were also found significantly different except for a number of seed/ pod, pod length and oil content.…”

Forty soybean genotypes were evaluated for two consecutive years kharif 2018 and 2019 to determine genetic variability, heritability (h 2 ) and genetic advance (GA) for yield and other yield attributing traits. The pooled analysis of variance revealed significant variation among year and treatment for all characters studied. The interaction of year x treatment also showed a significant difference for most of the traits. RVSM2011-35 recorded the highest mean performance of seed yield/plant and a high value of oil content over the two years indicating that the genotype was found to be promising and could be recommended for Assam. In the case of oil content, NRC 148 showed the highest mean value and also a high value of mean seed yield/ plant over the two years. Range estimation showed wide values for most of the traits except plant height, the number of branches and pods/plant in comparison with the check. The estimates of phenotypic (PCV) and genotypic (GCV) coefficient of variation indicated that the values of PCV were slightly higher than GCV. The highest values of GCV and PCV were observed for seed yield/plant, the number of seeds/pod and oil content. Higher values of heritability (h 2) coupled with high genetic advance (GA) were recorded for seed yield/plant, the number of seeds/pod, oil content, the number of branches, days to 50% flowering, plant height, the number of pods/plant, and 100 seed weight, suggesting that these characters could easily be modified or improved through simple selection.
