Abstract: X
The present investigation entitled “Study of combining ability and heterosis in F1 generation of bread wheat (Triticum aestivum L.)” was conducted at Crop Research Farm, Nawabganj, C. S. Azad University of Agriculture and Technology, Kanpur- 208 002. (U.P.) during rabi season, 2017-18. The experimental material comprised of parents and 28 F1s developed by crossing of 8 genotype viz., HD 3171,WH 147,K-906,K 307, K 1006,K 7903, DBW 14 and PBW 502 in half diallel design to study the twelve quantitative character viz., day to heading (75%), plant height(cm), days to maturity, number of tillers per plant, spike length(cm), number of spikelets per spike, number of gains per spike, weight of grain per spike(g), 1000 gains weight (g), biological yield per plant(g), gain yield per plant (g) and harvest index in bread wheat. The analysis of variance revealed highly significant differences among the genotypes for all the 12 characters. In this study the high heritability (narrow sense) were recorded for plant height, days to maturity, number of spikelets per spike, spike length, biological yield and grain yield per plant while moderate heritability were found for days to heading, tillers per plant, 1000 grain weight, grains weight per spike and harvest index whereas grains per spike showed low heritability.
