Estimation of Genetic Variability and Heritability for Seed Yield Characters in Greengram [Vigna radiata (L.) Wilczek]

Genetic Variability Studies in Segregating Populations (F2 and F3 Generations) in Green Gram (Vigna radiata (L.) Wilczek.)

“…Moderate PCV and GCV were observed for this trait in PUSA 0871 x TNY local (F 3 ). Similar reports were given by Sanjupretham et al, (2019).…”

“…The mean plant height ranged from 30.19 cm (MH 521 x TNY Local) to 46.16 cm(MH 565 x CO 6) in F 2 and from 33.13 cm (MH 521 x TNY Local) to 44.25 cm(PUSA 0871 x CO 6) in F 3 (Table 3). GCV was recorded low to moderate and PCV was moderate in both the generations except F 3 of ML 1451 x CO 6 recorded low PCV (9.14) and F 2 of PUSA 0871 x TNY Local exhibited high PCV (20.57).These findings are in confirmation with Marak and Sarkar (2017) and Sanjupretham et al, (2019) Shiv et al, (2017).…”

“…The estimates of GCV and PCV were low of all the crosses in both the generations except ML 1451 x CO 6 with moderate PCV values. Similar reports of low PCV and GCV were given by Shiv et al, (2017) and Sanjupretham et al, (2019).Low to moderate heritability and low GA as percent of mean were exhibited by this trait. The crosses ML 1451 x CO 6, MH 565 x CO 6 and MH 521 x TNY Local exhibited moderate heritability in both F 2 and F 3 generations indicating the predominant role of nonadditive gene action in expression of the trait (Mehandi et al, 2013).…”

“…There was no prominent variation in this trait for all the crosses in both F 2 and F 3 generations. Most of the crosses showed similar range for this trait ( Similar reports were given by Muthuswamy et al, (2019), Sanjupretham et al, (2019) and Talukdar et al, (2020).…”

“…The crosses ML 1451 x CO 6, MH 565 x CO 6 and MH 521 x TNY Local exhibited moderate heritability in both F 2 and F 3 generations indicating the predominant role of nonadditive gene action in expression of the trait (Mehandi et al, 2013). Similar results of low GA as percent of mean were exhibited by Sanjupretham et al, (2019) and Talukdar et al, (2020).…”
