Grapevine rootstock germplasm will be screened for resistance to aggressive virulent root-knot nematodes, crosses made, and resistant seedling selections identified through screening. About 50 selections will be screened. Evaluation will be done on two mapping populations, PC1173 has about 75 lines and PC010103/PC0978 has about 200 lines to evaluate. To obtain reliable screening results of nematode resistance, 5 or more propagated lines will need to be screened of each line.
