 ABSTRACT

To enhance productivity in barley crop, varieties having good combining ability are required. Because, the choice of the most suitable breeding method depends mainly on the combining ability behaviour vis-a-vis nature of gene action involved in the control of the trait of interest to the breeder. Therefore, the present research investigation was carried out with 10 parent half diallel set consisting of parents, F1’s and F2’s to estimate the general and specific combining ability variances and effects. Overall appraisal of present investigation manifested that the parent BH 959 and RD 2786 emerged as good general combiners for yield and its attributing traits, while among the crosses BHS 400 x BH 959, BH 959 x RD 2786 and PL 426 x RD 2552 emerged as good crosses for grain yield per plant as well as for other yield contributing characters. Parents BH 946, BH 902 and BH 959 has high yield coupled with high malt quality hence can be also used for malting quality purpose.

Key words: Barley, Combining Ability, Half Diallel, GCA, SCA.
