【摘要】 对 1 999～ 2 0 0 1年黑龙江省各大豆育种单位育成的 2 1 1份大豆新品系进行大豆灰斑病菌的混合菌种接种鉴定 ,三年的鉴定结果是 ,表现高抗的只有 1份 ,表现抗病的 39份 ,占供试材料的1 8.4 8% ,中抗的 78份 ,比例是 36 .97% ,表现感病的 93份 ,比例为 4 4.0 8%。对来自 7个生态区的大豆品系抗性分析结果表明 ,各生态区供试材料中 ,抗病品系比例由高到低依次为 :八一农大 -绥化 -哈尔滨 -佳木斯 -北安 -九三局 -黑河 ;中抗品系比例由高到低依次为哈尔滨 -佳木斯 -绥化 -北安 -九三局 -八一农大 -黑河 ;感病品系比例由高到低依次是黑河 -九三局 -北安 -绥化-佳木斯 -哈尔滨 -八一农大。更多还原

【Abstract】 new soybean lines were inoculated with the main races of 10 races of C.sojina. The results were as follows: In 1999-2001, among 211 new soybean lines, only one line was significantly resistant, 39 lines were resistant (18.48% of the total tested materials), 78 lines were moderate resistant (36.97% of the total tested materials), 93 lines was susceptible (44.08% of the total tested materials)to main races of C.sojina. Resistant lines proportions from high to low were: Bayinongda →Suihua→Harbin→Jamusi→Beian, Jiusanju, Heihe; moderate resistant lines proportions from high to low were: Harbin→Jamusi→Suiha→Beian→Jiusanju→Bayinongda→Heihe; susceptible lines proportions from high to low were Heihe →Jiusanju→Beian→Suihua→Jiamusi→Harbin→Bayinongda.更多还原
