Abstract
The 'Harosoy' soybean cultivar was considered to be the universal suscept for Phytophthora megasperma f. sp. glycinea when it was included in the differential host series for this pathogen (Haas and Buzzell, 1976). However, Moots (1982) reported that an Rps allele pair was present in Harosoy that conferred resistance to races 12 and 16. Harosoy is also resistant to races 18 and 19 but is susceptible to all other races 1-25 (unpublished results).
