Abstract
Thirty double crosses alongwith two checks Hicorn-984 and Hicorn 11+ were studied for ears plant-1, plant height, ear height, days to 50 % tasseling, days to 50% silking and grain yield plant-1 through phenotypic coefficient of variability, genotypic coefficient of variability, broad sense heritability, genetic Advance, correlations and path coefficient analysis. Significant differences were found among the crosses for ears plant-1, plant height, ear height and highly significant differences for days to 50 % tasseling, days to 50 % silking and grain yield. Grain yield plant-1 followed by days to 50% silking and days to 50 % tasseling were found high heritable traits for grain yield improvement. Plant height followed by ear height, days to 50 % tasseling and days to 50 % silking had strong genotypic and phenotypic association with each other and significantly positive genotypic correlation with grain yield too. Plant height followed by days to 50 % tasseling also exerted positive direct effect on grain yield.
