Variability Studies on Biparental and F₃ Progenies in Brinjal

Biparental progenies were developed in F₂ populations of three inter-varietal crosses in brinjal, using the North Carolina Design-1. The plants used in matings were also selfed to develop F₃ progenies. Phenotypic variability in general, as revealed by the co-efficient of variation, was greater in biparental progenies as compared to F₃ progenies with a few exceptions in all the crosses for all the characters. The average mean performance of the biparental progenies was also superior to F₃ progenies for all the characters except for number of fruits per plant and fruit diameter in cross KS-352 x Punjab Barsati, where mean performance was similar in both BIP's and F₃ progenies.
