Abstract:
wheat is one of the most significant cereal crops. It is possible to trace the beginnings of wheat to Asia Minor. It occupies more than 17% of all arable land, is consumed by nearly 40% of the world’s population, and makes up roughly 32% of all cereal growing land. Over 4.5 billion people in developing countries rely on it to meet 21% of their protein needs. The experimental material for the present investigation comprised of 45 F1s developed by crossing 10 lines viz., DBW-187, HD-3249, K-1006, PBW-723, PBW-757, HD-3271, HD-3298, K-8434, K - 9107, KRL-350 by following half diallel mating design. The experimental materials consisted of 55 genotype (45 F1s + 10 Parents). The high heritability in broad sense was estimated for all the characters except for day to 50% heading, flag leaf area (cm2), number of leaves/main tiller, number of spikelets/ear and protein content (%) in F1 generation.. A high value of heritability suggests that it could be due to a higher contribution of genotypic components. The estimate of genetic advance in percentage over mean ranged from 0.16 (flag leaf area) to 39.18 (Grain yield / Plant (g)) in F1 generation. The high genetic advance in percent over mean was observed in, biological yield per plant, Grain yield / Plant (g)), productive tiller per plant and seed hardness.
