breeding for drought stress is one the important purposes in wheat cultivars breeding programs. grain yield under drought stress is depended on phonological, morphological and physiological features. in order to investigate the general and specific combining ability and genes function under drought stress in three and two bread wheat lines and cultivars respectively, diallel one way cross was p...

to study combining ability and genetic parameters of seed yield trait in rapeseed, eight lines of rapeseed were evaluated by a design of half diallel cross. seeds of f1 generation and their parents were grown in a 6 × 6 simple lattice design with two replications. according to the analysis of variance, general combining ability (gca), specific combining ability (sca) and mean squares of genotyp...
