Abstract:

Eighty soybean germplasm lines were investigated for their resistance to Phytophthora sojae u-sing mixed culture by the hypocotyls inoculation technique.And the same time , the resistance of 69 linesto 7 physiological races of Phytophthora sojae were identified .The results indicate that 6 lines resistant toPhytophthora sojae ,12 lines intermediate response and 62 susceptible to Phytophthora sojae , the propor-tion were 7 .5%, 15% and 77.5% respectively .Among the tested lines , 12 resistant to 7 physiologicalraces of Phytophthora sojae (1, 3,9 ,11,17,21, 24)and 4 showed intermediate response , the ratio are 17.4%and 5.8 %.Only 1 line showed intermediate response to race Number 1,9 ,11 and 24, rate 1.5%.Bothin mixed culture tests and single physiological race tests,the resistance of equal lines to Phytophthora sojaewas the same .
