Development of a High-Density Genetic Map for Muscadine Grape Using a Mapping Population from Selfing of the Perfect-Flowered Vine 'Dixie'.

Intraspecific diversity of the immune grape Michaux. can serve as a rich source of valuable resistance loci to the most widespread pathogens and pests of grapevine. While only one resistance locus has been introgressed from to the gene pool, a number of other genes conferring resistance to powdery mildew and downy mildew have been identified in various cultivars.

Introgressions of Vitis rotundifolia Michx. to obtain grapevine genotypes with complex resistance to biotic and abiotic stresses.

Vitis rotundifolia Michx. is one of the species of the family Vitaceae, with resistance to both biotic and abiotic stresses. The present study reports new scientif ic knowledge about the inheritance of resistance to downy mildew, powdery mildew and frost by V.
