用大豆种质PI88788和Peking与应县小黑豆的回交后代 (BC1 F2 )鉴定大豆对胞囊线虫(SCN) 1号生理小种的抗性遗传 ,结果表明 ,抗源应县小黑豆对胞囊线虫 1号生理小种的抗性遗传受隐性基因控制 ,与PI88788存在 1对基因差异 ,与Peking存在相同的抗病基因
The inheritance of soybean resistance to cytoplasmic nematode (SCN) 1 race was identified by using soybean germplasm PI88788 and backcrossing progeny of Peking and black bean of Yingxian (BC1 F2). The results showed that the resistance of soybean to cytoplasm The cytoplasmic resistance of Cyst nematode 1 was controlled by the recessive gene, and there was one pair of gene differences with PI88788, which had the same resistance genes as Peking
