Narrative
US 4808 was collected in 1986 from a wild population of Fragaria viriniana in Minnesota. this clone appears typical of native populations in terms of morphology, runnering, flowering, responses, and fruit development. The outstanding feature of US 4808 is its high degree of resistance to infection by highly viulent strains of Xanthomonas fragariae. It was tested against X. fragariae strains Xf3, Xf6, and ATCC 33239, each representing one of the four recognized differentially pathogenic strain groups of X. fragariae. US 4808 was not tested or selected for reistance to other diseases. In a cross with a highly susceptible variety, US 4808 transmitted resistance to 8-12% of its progeny, depending on the virulence of X. fragariae strains, and it should be a suitable disease-resistant parent for breeding disease-resistant varieties adapted to different cultural systems and environments.
