Selection criteria in F-3 and F-4 population of mungbean (Vigna radiata (L.)Wilczek)

摘要

Five cross combinations of mungbean viz., NM 92 x NM 51,NM 92 x Pusa Baisakhi, NM 92 x NM 93, NM 92 x CV. 6601 and CV. 6601 x NM 92 in F-3 and F-4 generations were studied for genetic parameters and direct and indirect effects of different morphological traits on yield. Based on results of genetic parameters, populations of CV. 6601 x NM 92 and NM 92 x Pusa Baisakhi for pods per plant and NM 92 x CV. 6601 for 100 seed weight in F-3 and NM 92 x CV. 6601, NM 92 x NM 93, and CV. 6601 x NM 92 in F-4 showed additive type of genes as the said traits in these particular cross combinations contain high heritability values combined with high genetic advance. Population of NM 92 x Pusa Baisakhi, NM 92 x NM 51, NM 92 x NM 93 and NM 92 x CV. 6601 in F-3 and NM 92 x CV. 6601, NM 92 x Pusa Baisakhi, CV. 6601 x NM 92 and NM 92 x NM 51 in F-4 showed positive direct effects for branches per plant, pods per plant, 100 seed weight and seeds per pod.
