Abstract: Introgression line (IL) population DH 86 × ISATGR 278-18 was developed by crossing cultivated variety of groundnut viz., DH86 with the synthetic amphidiploids (ISATGR 278-18) and backcrossing twice with the recurrent parents to generate 51 BC2F4 ILs.Field evaluation of the ILs during kharif 2011and kharif 2012 showed considerable variability and heritability for most of the agronomic and productivity traits. ILs showed normal distribution agronomic and productivity traits. Most of the agronomic and productivity traits were positively correlated. Thus, indicating importance of these traits for enhancing the productivity in the populations.
Keywords: Agronomic traits, Kharif, Backcrossing, Synthetic amphidiploids
