| 摘要 |
The present invention relates to a novel mutant allele of Cucurbita pepo L. (pumpkin) designated Pm2, which confers a strong and consistent powdery mildew resistance to Cucurbita pepo plants. The present invention also relates to plants and seeds of the family or line carrying the Pm2 allele. In addition, the present invention is also directed to transferring the Pm2 allele to plants in the same species lacking the allele, and is useful for producing novel types and varieties of powdery mildew resistant Cucurbita pepo.
