The present study was conducted at GBPUA & T Pantnagar Uttarakhand during Kharif 2015 to study various parameters of genetic variability, broad sense heritability and genetic advance estimates in inbred line of maize. Analysis of variance revealed that the mean sum of squares due to genotypes showed significant differences for all the 11 characters studied. Traits grain yield/ha, days to 50% tasselling, days to 50% silking, number of kernels per row, 100-kernel weight were showed high heritability accompanied with high to moderate genotypic and phenotypic coefficient of variation and genetic advance in both the environments (OPD and HPD).Which indicates that most likely the heritability is due to additive gene effects and selection may be effective in early generations for these traits. Whereas high to moderate heritability along with low estimates of genetic advance were observed for days to 50 per cent tasselling, days to 50 per cent silking, ear length and number of kernel rows per ear.
