| Abstract:
Grape rootstock improvement at the United States Department of Agriculture Agricultural Research Service Grape Genetics Research Unit includes introduction, evaluation and breeding. The primary goal is the enhancement of nematode resistance in rootstocks that provide protection against phylloxera (resistance and tolerance). Phylloxera protection is a requirement of all elite selections in the program. Vineyard trials are in place for regions across the United States and with several varieties. Germplasm collection and evaluation to identify superior novel parents for breeding and introduction are carried out in cooperation with the germplasm repository system and other cooperators; selected individuals from diverse Vitis species including V. cinerea and V. cordifolia as well as related genera are in use in our program. | |
