Abstract: The present study was carried out at College of Agriculture, University of Agricultural Sciences, Dharwad during kharif, 2017 to determine the various parameters of genetic variability, broad sense heritability and genetic advance estimates in newly developed S2 progenies through reciprocal recurrent selection. Analysis of variance revealed that the mean sum of squares due to genotypes showed significant differences for all the 12 characters studied. High to moderate estimates of GCV and PCV were recorded for Grain yield, number of kernels per row, 100-grain weight, ear length and plant height which represents considerable variability and offers scope for genetic improvement through selection. High estimates of genetic advance coupled with high heritability was recorded for Grain yield, 100-grain weight, ear height and plant height which further leads to improvement of traits under selection. Thus provides better opportunities for selecting plant material for these traits in maize breeding program.
