ABSTRACT
The physical properties of wheat grain strongly influence on yield and have direct or indirect impact on the wheat milling and baking quality. Association of yield and physical traits of grain in 33 spring wheat genotypes were examined under field experimental conditions during the wheat crop season of 2020-21. The experiment was set up in a three-replications through randomized complete block design (RCBD). Analysis of variances revealed that all the studied parameters, like spikelet per spike (SPS), number of grains per spike (NGS), grain yield per plant (GYP), grain length (GL), grain width (GWD), grain area (GA) and grain sphericity (GS) differed significantly among all genotypes, indicating the presences of genetic variability. Yield related traits like SPS, NGS, and GYP is positively and highly correlated with GL, GW, GA and GS which exhibited the importance of these indices in studied germplasm. It was therefore suggested that positively and significantly correlated traits can be used for future breeding programs. The genotypes G33 followed by G20 and G22 well performed while the genotypes lowest performed G19 followed by G15 and G13 in yield and grain’s physical attributes in the current experiment. It will help the breeders for the selection of high yielding genotypes by only identifying plant yield and physical grain’s attributes to develop the high yielding wheat varieties.
