In ten wheat varieties (Chenab79, Indus79, Barani79, Punjab81, Pavon, WL711, Sandal, LU26, Nacozari and V1316) genetic coefficient of variability was higher for grain yield per plant (12.18%) followed by 1000 grain weight (10.15%), number of spikelets per spike (5.34), number of grains per spike (5.14%) and number of spikes per plant (3.24%). Heritability in the broad sense was higher for 1000 grain weight (99.60%) and number of spikelets per spike (75.70%) than other traits. Genetic advance (% of mean) was higher for 1000 grain weight (20.86%) followed by grain yield per plant (19.04%). Higher direct effect on grain yield per plant was exerted by 1000 grain weight (0.8460) followed by number of grains per spike (0.4465), number of spikes per plant (0.3539) and number of spikelets per spike (0.0126).
