Abstract: In the present investigation sixty-three single cross hybrids were evaluated in 9 x 7 alpha lattice to study the Correlation, genetic variance, heritability and genetic advance among different quantitative traits to determine the efficiency of selection in a breeding programme. Accordingly, the higher phenotypic variance than genotypic variance was recorded for most of the traits. However, the difference between PCV and GCV was very minimal for most of the traits except grain yield indicating selection for grain yield provides less chances as compared to other traits. Plant height, hundred seed weight and cob length recorded high heritability along with high genetic advance indicating positive response upon selection. Correlation study revealed that grain yield was significantly correlated with days to 50 per cent tasseling, days to 50 per cent silking, plant height, ear height, number of kernels per row, cob girth, cob length, and hundred grain weight.
