Genetic variability created through biparental mating in chickpea (Cicer arietinum L.)

Abstract

Biparental mating was attempted in the F2 of ICCV-10 x SG-256 cross of chickpea (Cicer arietinum L.). The biparental population (SIP) had better mean performance than the F3 selts for all the characters under study. The lower limit of the range was, in general, smaller for almost all the characters in the SIP. The upper limit" had also increased in the desired direction for all the characters. Sufficiently high genetic variation was maintained In the SIP population for most of the characters except for secondary. branches. SIP also exhibited improved estimates of heritability and genetic advance. The utility of biparental mating in early segregating generations in chickpea is emphasized.
