A germplasm release that exhibits a high degree of resistance to bacterial angular leaf spot disease caused by Xanthomonas fragariae. Origin: developed by J.L. Maas, T.C. Gouin, S.C. Hokanson, and J.S. Hartung, USDA–ARS, Beltsville, Md. Selected from a wild population of Fragaria virginiana collected in Minnesota in 1986; tested as SG-89. Fruit and Tree: Clone appears typical of native populations in terms of morphology, runnering, flowering responses, and fruit development. High degree of resistance to infection by highly virulent strains (Xf3, Xf6, 1425, and ATCC 33239) of X. fragariae. The type of resistance exhibited is hyposensitive in that inoculated tissues do not rapidly develop into necrotic areas and bacteria do not spread form inoculated tissues into healthy tissues. Not tested or selected for resistance to other disease. In a cross with highly susceptible cultivar, transmitted resistance to 8% to 12% of its progeny. Fruit:
