- Abstract
Phytophthora root and stem rot, caused by Phytophihora sojae, is an economically important disease of soybean (Glycine max) in Heilongjiang Province of China. Forty - four soybean cultivars were evaluated for their responses to P. sojae race 1 , 3 , 4, 5 , 9, 13 , 44 and 54. Results showed that resistant and intermediate cultivars to the eight races accounted for 29.5% ,40. 9% ,43. 2% ,36. 8% ,45. 5% ,31. 8%, and 72.7% respectively. Forty-four soybean cultivars elicited 37 different reaction types with the eight P. sojae races. Hefeng -44 and Suinong - 12 were deduced to have gene Rps1c or the combination of Rps1a and Rps1c, Rps1c and Rps6, Rps1c and Rps7. Heihe -32 was deduced to have the combination of gene Rps1a and Rps1d. Other cultivars could carry this new single gene or combination of these two genes respectively. It was suggested that there were abundant germplasm resources that resisted Phytophthora root and stem rot of soybean in Heilongjiang Province.
