Higher heritability coupled with high genetic advance was recorded for biological yield per plant, grain yield per plant, indicating that these characters are governed by additive gene action and hence direct selection for these traits will increase grain yield through genetic improvement in wheat. Significant positive correlation was observed for grain yield/plant with biological yield/plant, harvest index, spike length, spike weight, number of grains per spike, number of tillers per plant. Hence, selection for these characters may be utilized for the improvement of grain yield. The cluster I...
Higher heritability coupled with high genetic advance was recorded for biological yield per plant, grain yield per plant, indicating that these characters are governed by additive gene action and hence direct selection for these traits will increase grain yield through genetic improvement in wheat. Significant positive correlation was observed for grain yield/plant with biological yield/plant, harvest index, spike length, spike weight, number of grains per spike, number of tillers per plant. Hence, selection for these characters may be utilized for the improvement of grain yield. The cluster II has plant height and peduncle lengths, cluster III spike length, cluster IV days to 50% heading and days to 50% flowering, cluster VI number of tillers per plant, spike weight, 1000 seed weight, biological yield per plant grain yield per plant, grains filling period and days to maturity and cluster VII number of grains per spike and harvest index, cluster VIII flag leaf areas and spike weight. The genotypes from clusters VI and IV, cluster VIII and III, cluster VIII and VII, cluster VII and V are used for crossing.
