Wheat is a cereal that is majorly consumed around the world. There is a dire need for the advancement of wheat cultivars that are producing high yield. The experiment was conducted to characterize the spike related traits of wheat genotypes. Twenty wheat genotypes comprising three replications were experimented using randomized complete block design. The difference was significant among the studied twenty genotypes revealed by analysis of variance. Correlation Pearson’s revealed that the number of grains per spike (GPS) has positive relationship among all the studied traits such as the number of tillers per plant (NTP), spike weight (SWT), spike length (SL), and grain yield per plant (GYP). The GYP has a strong positive association with GPS (0.81**), GYS (0.78**), and SL (0.68**). The biological yield had a non-significant association with GYS (0.28) and GPS (0.13). All studied attributes have variations in the mean values which were represented by Radar analysis. The genotype Sadiq-21 was the best performing genotype among the SWT, GYS and BY followed by genotype Nawab-21 which performed best among the NTP, GYS and GPS and genotype Ghazi-19 which performed good among BY, SWT and GPS. The genotypes that were among the worst performing were Suren-10, Galaxy-13 and Borluag-16. The result of our study showed grain yield was mainly affected by NTP, GYS and GPS. For the improvement of wheat yield, these attributes must be improved for selection so that the yield of the wheat can be increased because these have a strong association with the grain yield.

The morphological traits of wheat grain strongly influence on yield and directly affect the grain yield of the crop. The necessity to overcome the human demand of wheat the grain yield should be intensified. The current experiment was organized to study the morphological traits of wheat and their association with yield. The experiment was done in the randomized complete block design including three replications and twenty genotypes under normal condition in cropping season of 2021. The result of analysis of variance indicates that there is highly significant difference among the studied genotypes, traits like spikelet per spike (SPS), flag leaf area(FLA), grain yield per spike(GYS), number of grains per spike(GPS), biological yield (BY) and grain yield per plant(GYP) showed the genetic potential and variability among them. While traits plant height (PH) and peduncle length (PL) are significant. Correlation analysis showed that grain yield per plant is highly associated with flag leaf area (0.78**) followed by biological yield which is highly correlated with plant height (0.77**) and number of grain per spike was also highly correlated with spikelet per spike (0.70**).While spikelet per spike and number of grains per spike correlated non-significantly with plant height (0.21ns), (0.23ns) and biological yield correalted non-significantly with spikelet per spike (0.21ns).The highest mean values recorded by the genotype G3 for the traits SPS (21.22), PL (16.74) and BY (23.33), followed by the genotype G14 for the traits SPS (23.22), PL (17.36), FLA (15), GPS (35.83) and by the genotype G19 for the traits PH (94.63), BY (22.23), GPS (33.16). Hence, in breeding or selection program, to develop the high yield of wheat cultivars in selection or breeding program, these yield related traits should have strong and positive association.
