DIAZ-GARCIA LAB

Germplasm

Our grapevine breeding program harbors a large collection of Vitis germplasm and grape varieties. As we primarily focus on rootstock and wine grape breeding, most of our materials contain useful allele variation for resistance/tolerance to biotic and abiotic stressors, as well as wine quality characteristics. Below there is a list of the germplasm found in our collection, and some of the rootstocks/scions developed by previous breeders in the program.
