Wild introgression lines have wider genetic diversity than normal cultivars and contribute for crop
improvement. Segregating populations consisting of 161 families at F3
and F4 generations derived from BIL
(back cross introgression line) parents were used in the present study. Field evaluation for yield traits were
carried out during two seasons of rabi and kharif in 2017. Correlation analysis was performed to determine
associations among yield traits and highly significant association was observed for SPY with TDM and HI
in F3
and F4
generations. Significant positive association of TN, PTN with SPY and also highly significant
negative association between SPY and TGW were observed in F4
. All the traits in F3
and F4
showed positively
skewed distribution except for the traits, PH and TGW. Significant lines were identified through pair wise
mean comparisons with parents 166S, 148S and Swarna. Four lines C3
-53, C3
-38, C3
-70, and C3-96 exhibited
positively significant values for TGW compared with parents. These lines can be used further for yield
improvement and genetic dissection of target traits
