中文摘要：
由大豆疫霉菌引起的大豆疫霉根腐病是严重影响大豆生产的毁灭性病害之一.防治该病经济有效的方法是抗病育种,而抗性资源筛选又是抗病育种的基础.本研究采用下胚轴伤口接种法,用黑龙江省的大豆疫霉菌的1号优势生理小种对来自全国19个省份的415份野生大豆资源进行了抗性鉴定,表现抗病的有96份,占总鉴定资源的23.1%,表现中抗的资源有152份,占36.6%,表现感病的资源有167份,占40.2%.根据野生大豆的来源分析发现,在我国,抗性野生大豆资源分布较广泛.
英文摘要：
Phytophthora root rot caused by P. sojae was a destructive disease in soybean production regions all around the world. Utilization of resistant varieties was the most economical and environmentally safe method for controlling the disease. And it was base in fastness resource filtration. 415 wild soybean accessions from 19 province in China were identified for their reaction to race 1 of P. sojae from Heilongjiang and using the hypocotyls inoculation technique. The results indicated that there were 96 lines resistant to Phytophthora sojae, and 152 lines intermediate responsed to P. sojae and 167 susceptible to P. sojae. Their proportion was 23.1%,36. 6~ and 40.2% respectively among the tested lines. The results indicated that the distribution of wild soybeans resistant to race 1 of Phytophthora was extensive in China.
