大豆胞囊线虫3号生理小种是东北大豆产区分布最广、危害最大的生理小种,五寨黑豆对包括大豆胞囊线虫3号生理小种在内的7个生理小种具有高抗性.以黑龙江省主栽品种合丰35为母本,与五寨黑豆进行杂交,通过鉴定F2、F3代对大豆胞囊线虫3号生理小种的抗性,研究了五寨黑豆对大豆胞囊线虫抗性遗传.结果表明:在以合丰35为遗传背景下,五寨黑豆对SCN 3号生理小种的抗、感分离比例符合孟德尔遗传规律中1∶3的分离比例,表明五寨黑豆对SCN 3号生理小种的抗性是由1对隐性基因控制.
Genetic Analysis of Resistance to Soybean Cyst Nematode (SCN) Race 3 in Soybean Germplasm Wuzhaiheidou
Soybean cyst nematode (SCN) race 3 is widely distributed and severely harmed soybean yield in the main soybean producing area of northeastern of China.Wuzhaiheidou can resist 7 races containing SCN races 3.In this study,genetic resistance of soybean germplasm to SCN race 3 was studied with the populations of F2 and F3 lines in crosses of Hefeng 35 and Wuzhaiheidou.The results showed that the separation ratio of Wuzhaiheidou resistance to SCN race 3 was 1 ∶ 3 in according with Mendel laws.It was cleared that the resistance of Wuzhaiheidou to SCN races 3 was controlled by one recessive gene.
