Abstract:

Biparental mating is helpful for creating variability and determines the relative importance of genetic components of variance (additive and dominance components of variance) as well as expected response to selection of a trait in formulating and effective breeding programme for its genetic improvement. Both additive and dominance components of variance shows significance for yield and yield contributing characters. In general, biparental population (BIP) had better mean performance than the selfing series for all the characters. The lower and upper limit of range generally increases with high genetic variance is maintained in the BIP population for most of the characters. BIP also exhibited improved estimates of heritability and genetic advances. Thus, the utility of the biparental mating in early segregating generation is emphasized in crop improvement programme.
