Abstract:
An experiment has been conducted at the Agricultural Research Field of Department of Genetics and Plant Breeding, Rama University, Kanpur to understand the pattern of genetic variability and heritability through the investigation of 27 wheat genotypes including checks. The trial has been conducted in randomized block design in three replication and the observations have been noted on the eleven metric traits viz., days to 50% flowering, days to maturity, flag leaf area (cm²), number of tillers per plant, plant height (cm), spike length (cm), number of spikelets per spike, grain yield per plant (g), biological yield per plant (g), 1000-grains weight (g) and harvest index (%). The analysis of variance showed a significant mean sum of squares due to all traits under study. High estimates of heritability were observed for all of the traits viz., grain yield per plant (94.90%) followed by 1000-grains weight (94.03%) and harvest index (93.85%), whereas, high estimates of genetic advance (>20%) in percent over mean was recorded for the traits grain yield per plant (24.76%) followed by spike length (22.22%), 1000-grains weight (21.88%). High heritability accompanied with high genetic advance for the traits showed additive gene action and the selection for such traits would be rewarding.
