摘要报道了两项实验，涉及短日照基因型与常熟或日中性基因型之间杂交的后代。使用主观五点量表在田间对白粉病（Sphaerotheca maularis）的易感性进行了评估。发现一般配合力（GCA）和特异性配合力（SCA）在抗霉性的遗传中具有重要意义。 Tioga 品种被认为是具有良好 GCA 的有用抗性来源，而 ES657 × Brighton 杂交则显示出高水平的 SCA。
SummaryTwo experiments are reported involving the progenies from crosses between short-day and either everbearing or day-neutral genotypes. Assessments of susceptibility to powdery mildew (Sphaerotheca macularis) were made in the field using a subjective five-point scale. Both general combining ability (GCA) and specific combining ability (SCA) were found to be significant in the inheritance of mildew resistance. The cv Tioga was identified as a useful source of resistance with good GCA and the cross ES657 × Brighton showed a high level of SCA.
