Abstract By adopting complete diallel crossing method,inheritance of powdery mildew in bitter ground was studied at seedling stage.The results showed the resistance was controlled by at least two pairs of genes,and was incompletely recessive.Effect of backcross was very significant and that of reciprocal cross was not.Resistance was dominated by nuclear genes,narrow inheritability was comparatively high.The resistance was in keeping with additive-dominance model,and dominance was dominating,and showed a quantitative...
