Evaluation of genetic variability, heritability and genetic advance in blackgram [Vigna mungo (L.) Hepper]

Abstract

An attempt was made to study blackgram germplasm with an objective to develop genetically diverse genotypes accompanied with high heritable components of yield contributing traits. The experimental material comprised of 21 blackgram genotypes, was examined during kharif 2015 and 2016. Experimental study conducted during kharif 2015, was mainly relied on selection of transgressive segregants, which were further analyzed in Compact Family Block Design during kharif 2016. The results depicted that families and progenies within families were significantly different for majority of the traits and found to be highly variable for biological yield, harvest index and seed yield. High heritability coupled with high genetic advance were recorded for plant height (74.15%, 33.12%), branches per plant (84.34%, 40.55%), biological yield (83.51%, 69.11%) and seed yield (84.50%, 66.11%). Thus, the present findings could be beneficial to develop superior genotypes through selection in blackgram breeding program.

Genetic Parameters of Variation for Seed Yield and its Component Traits in Black Gram (Vigna mungo L. Hepper)

“…The results found were presented in Table 1. These findings are authorization with the finding of Singh et al, (2020), Shalini and Lal (2019), Aftab et al, (2018), Chauhan et al, (2018), Vidya et al, (2018), Bishnoi et al, (2017), Rolaniya et al, (2017), Tank et al, (2017), Jyothsna et al, (2016), Priyanka, et al, (2016), Sohel et al, (2016, Usharani and Kumar (2016), Veeramani et al, (2005) in black gram.…”

“…Results obtained from these components of genetic parameter indicate presence of abundant amount of genetic variability in the material under present investigation. These findings are in authorisation with the findings on the reports of Chowdhury et al, (2020), Singh et al, (2020), Sathees et al, (2019), Chauhan et al, (2018), Priya et al, (2018), Verma et al, (2018, Sinha et al, (2018), Panigrahi et al, (2014), Singh et al, (2014), Sowmini and Jayamani (2013).…”

Multivariate Analysis in Blackgram (Vigna mungo L. Hepper) Genotypes in India

“…The traits were seed yield per plant (18.89%), plant height (11.32%), number of pods per cluster (10.5%) showed moderate phenotypic coefficient of variation. Similar results were reported by Chauhan et al [14], Sowmini et al [15]. Heritability varied from 17.11% (Pod length) to 92.71% (Biological yield).…”

Studies on Combining Ability for Seed Yield and Its Related Traits in Blackgram [Vigna mungo (L.) Hepper]

“…Hence, it offers a better scope for further improvement of breeding material by the selection of promising genotypes in blackgram breeding programme. The significant variation for all the traits was also observed by earlier workers viz., Kumar et al (2017) for seed yield, number of branches, pods, clusters, 100-seed weight, fodder biomass and harvest index; Chauhan et al (2018) for all studied traits; Bandi et al (2018) for days to 50% flowering, days to maturity, plant height (cm), number of branches per plant, number of clusters per plant, number of pods per plant, pod length (cm), number of seeds per pod, 100-seed weight (g) and grain yield per plant (g) in blackgram.…”
