Abstract

In this paper, the present investigation aims to evaluate the correlation and path coefficients analysis under timely (E1) and late sown (E2) conditions through line × tester analysis. genotypes including 12 lines, 3 testers and their 36 F1s hybrids were evaluated for 12 morphological traits. The two different conditions were taken characters studied. The correlation coefficient of grain yield per plant showed high degree of positive significant association with days to 50% flowering, days to maturity, tillers per plant, Panicle length, number of spikelet’s per spike, number of grains per spike, biological yield per plant,1000 Grain Weight, harvest index, at phenotypic level and days to 50% flowering, days to maturity, tillers per plant, Panicle length, number of spikelet’s per spike, number of grains per spike, biological yield per plant, harvest index, at genotypic level. The path coefficients analysis of such character’s plant height, tillers per plant, number of spikelet’s per spike, number of grains per spike, biological yield per plant, harvest index exerted positive direct effect on seed yield per plant at both genotypic and phenotypic level while days to maturity, spike length, test weight/1000 grain reaction exerted negative direct effect on seed yield per plant at both phenotypic level and genotypic level.
