摘　　要：采用下胚轴伤口接种法评价了吉林和辽宁省49个主栽品种(系)对Phytophthora sojae13个不同致病型标准菌系的抗性。与鉴别寄主的比较分析表明,铁丰29,吉育67,沈农9号,吉育80推导含有Rps3a基因;铁丰31,吉育45,吉育90,九农34,铁豆42,铁豆43,铁豆44推导含有Rps3a和Rps1d双基因;辽豆18推导含有Rps3a和Rps1k双基因;辽豆17推导含有Rps1d和Rps6双基因;辽豆21,辽豆22和辽豆24推导含有Rps1a基因;九农29和九农35推导含有Rps1k基因。Phytophthora root and stem rot caused by Phytophthora sojae is a destructive disease in global soybean production.It is imperative to screen soybean cultivars （lines） or germplasms and identify resistance genes. In the present study,49 soybean cultivars or lines from Jilin and Liaoning provinces in China were identified using the hypocotyl inoculation technique.A comparative analysis of the reactions to 13 pathotypes of P.sojae were conducted using tested soybean cultivars and germplasms possessing Phytophthora resistance genes. The results suggested that Tiefeng 29,Jiyu 67,Shennong 9 and Jiyu 80 carried Rps3a;Tiefeng 31,Jiyu 90,Jiunong 34,Tiedou 42,Tiedou 43 and Tiedou 44 carried Rps3a and Rps1d; Liaodou 18 carried both Rps3a and Rps1k;Liaodou 17 carried Rps1d and Rps6; Liaodou21,Liaodou22 and Liaodou 24 had Rps1a; Jiunong 29 and Jiunong 35 had Rps1k.
