Abstract

In terms of both its age and usefulness as a source of food for humans, 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 28 F1s developed by crossing 8 lines viz., K- 9107, HD–2733 , HD– 2888, WH–1218, K–1313, DBW–187, HD–3086 , and DBW– 107 by following half diallel mating design. The experimental materials consisted of 36 genotype (28 F1s + 8 Parents). Accordingly, high estimates of heritability were observed for days to 75 % heading (days), days to maturity (days), plant height (cm), no. of tillers / plant, no. of grains /ear, no. of spikelet’s/ear and grain yield plant(g) in F1 generation. The moderate heritability estimate was found for ear length(cm) and 1000 grain weight(g). The estimate of genetic advance in percentage over mean ranged from 5.492 (No. of spikelet’s/ ear) to 41.668 (Grain yield / Plant (g)) in Fl generation. The high genetic advance in percent over mean was observed in number of tillers per plant, grain yield per plant (g).
