Abstract:
Thirty-six genotypes of wheat were studied for generating scientific information on nature and magnitude of genetic variability, heritability, genetic advance and correlation for designing breeding programme. The field experiment was conducted at Experimental Research Farm, Hol, MACS-Agharkar Research Institute during 2016-17. The data were recorded on days to heading, plant height (cm), reproductive period, days to maturity, 1000-grain weight (g), biomass (g), grain yield (g) and harvest index (%). Analysis of variance revealed significant differences among the genotypes for all the characters except biomass. High heritability coupled with high genetic advance was observed for plant height (cm), days to heading, 1000-grain weight (g), grain yield (g) and harvest index (%), indicating the presence of additive gene action and direct selection for such characters would be more effective. Biomass, harvest index and days to maturity gave the positive association with grain yield. Correlation of these traits will be useful to breeders in selecting genotypes possessing group of desired traits. From this study it was concluded that, the high grain yielding genotypes GW 491, HI 1624, HI 1625 and GW 498 were observed and these genotypes could be utilized in further breeding programme. Genotypes HI 1624 was found to be early maturing with high yielding, can be utilized as parent in crossing programme for further crop improvement or can be tested further to consider it for commercial cultivation.
