Abstract:
The current investigation involved the analysis of 90 wheat genotypes from an F5 segregating population to assess variability, heritability, and genetic advance. The analysis of variance demonstrated significant variability among the genotypes for 13 traits. The F5 progeny resulting from the cross DBW-110 X MP-3382 exhibited the highest grain yield per plant based on mean performance. Among the traits, high percent coefficient of variation (PCV) was observed in biological yield (34.51), followed by harvest index (33.01), grain yield per plant (30.23), ear weight (22.74), number of productive tillers per plant (21.81), chlorophyll content (18.45), test weight (15.1), number of grains per ear (13.67), number of spikelets per ear (13.54), ear length (11.9), plant height (10.52), days to maturity (6.98), and days to 50% heading (5.3). Similarly, high genetic coefficient of variation (GCV) was observed in biological yield (34.28), followed by chlorophyll index (32.99), harvest index (30.28), ear weight (20.53), number of productive tillers per plant (20.25), grain yield per plant (18.28), grain weight (14.44), number of spikelets per ear (13.18), number of grains per plant (12.91), ear length (11.21), plant height (10.18), days to maturity (6.9), and days to flowering (5.06). Furthermore, all the traits exhibited high broad sense heritability estimates. In particular, plant height, number of productive tillers per plant, ear length, number of spikelets per ear, ear weight, number of grains per ear, test weight, biological yield per plant, grain yield per plant, harvest index, and chlorophyll content demonstrated high heritability along with significant genetic advance. These results indicate that these traits can be effectively improved through direct selection.
