Molecular marker for selecting watermelon line or cultivar resistant to powdery mildew and use thereof

摘要

The present invention relates to the use watermelon powdery mildew resistance object to determine the molecular markers for and thereof, and more particularly to a method for determining the SNP marker compositions, primers, and watermelon powdery mildew resistance object by using this, to determine the watermelon powdery mildew resistance object will be. The provision of watermelon powdery mildew resistance molecular markers according to the present invention, PI 254744 do not have a direct inoculation of powdery mildew disease in developing resistant strains and varieties derived from watermelon can see immediately whether resistance to extract DNA from young plants or seeds.
