Abstract

Investigations were done at main agriculture research station of University of Agricultural Sciences, Dharwad, Karnataka in two seasons viz summer 2013–14 and kharif 2014 on 125 high oleic advanced breeding lines of groundnut along with 5 checks to study genetic variability present in them. Analysis of variance revealed significant variations among the high oleic advanced breeding lines, seasons and genotype x season interactions for all the traits evaluated. The phenotypic coefficient of variation was higher in magnitude than the genotypic coefficient of variation in respect of all the characters studied.
