Abstract:

9 diverse barley genotypes were selected and crossed in a diallel (without reciprocals) mating design to evaluate combining ability effects to identify promising crosses for 13 quantitative characters including yield and its components. Analysis of variance for diallel revealed highly significant differences for most of the traits investigated. Parent BH 393 has been excellent general combiner for majority of traits viz., days to 50 per cent heading, days to 75 per cent maturity. Another parent BH 959 has good general combiner for plant height, flag leaf area, number of effective tillers per plant, spike length, number of grains per spike, number of spikelets per plant, 1000-grain weight, and grain yield per plant. Followed by Parent RD 2786 has been good general combiner for protein content. Parents RD 2715, BH 959, BH 393 can be utilizing for developing of a variety by exploiting additive gene action. BH 959 and DWRB 64 these both the parents are of higher yielding these both the parent of higher grain yielding crosses viz., RD 2786 × BH 959, RD 2552 × DWRB 64, and RD 2035 × RD 2786. A perusal of specific combining ability effects revealed that positive significant sca effects for grain yield per plant was observed in eleven crosses viz., DWRB 91 × BH 959, RD 2552 × DWRB 64, RD 2035 × RD 2786, RD 2035 × BH 393, DWRB 92 × BH 393 RD 2715 × DWRB 64, RD 2715 × DWRB 91, BH 959 × DWRB 64, RD 2552 × RD 2715, RD 2035 × DWRB 92 and DWRB 91 × DWRB 64 expressed higher positive significant sca effects ranged from 1.17 to 2.50 along with good per se performance from 14.44 to 21.07. It is, therefore, the selective parents and crosses could be utilized for developing desirable crosses with high yielding towards exploiting the hybrid vigor or other related traits under crop improvement.
