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. | Study of combining ability analysis in barley (Hordeum vulgare L.)
