ABSTRACT

The experiment was conducted to study the variability parameters, correlations and path coefficient for ten agronomically important traits in the 40 bread wheat genotypes. Genotypic coefficient of variation (GCV) was less as compared to that of phenotypic coefficient of variation (PCV) for all the characters. Plant height and grain weight per plant had high GCV, heritability and genetic advance (as percentage of mean). This indicated that these characters were governed by additive gene effect and can be improved through selection effectively. Highly positive and significant correlation reported for grain yield per plant with number of tiller per plant, number of spikelets per spike, 100-grain weight and grain weight of main spike. The present study indicated that number of tillers per plant had highest direct effect on seed yield per plant both at genotypic levels and grain weight of main spike.
