ABSTRACT
Forty F1’s generated by cross of ten genetically diverse promising genotypes with well adapted 4 testers in a line x tester mating design, were evaluated in randomized complete block with 3 replications and two dates of sowing i.e. 2nd week of November (timely sown) and 1st week of January (very late sown). Moderate GCV values were recorded for three characters viz., harvest index, ear weight and number of productive tillers plant-1 under timely sown condition. While higher GCV values exhibited by ear weight and harvest index under very late sown condition. The estimates of heritability for all the traits revealed that heritability estimates increased with delay in sowing time except for harvest index. Economically important traits like grain yield plant-1, biological yield plant-1 and 1000-grain weight which exhibited high estimates for expected genetic advance accompanied with high heritability estimate can be improved by hybridization followed by selection. The study conclude that, correlated response obtained with grain yield plant-1 as a result of selection for different yield contributing traits viz; biological yield plant-1, number of productive tillers plant-1, ear weight exerted maximum response to grain yield followed by number of spikelets ear-1 and harvest index. Therefore, selection for grain yield plant-1 can be done through biological yield plant-1, number of productive tillers plant-1, number of spikelets ear-1 and harvest index.
Key words: Coefficients of variation, heritability, genetic advance, correlation
