采用生物间遗传学方法对哈尔滨小黑豆、长粒黑豆、小粒黑豆、磨石黑豆和连毛会黑豆与胞囊线虫豆、２、３、４、５、９、１２和１４号生理小种相互关系进行了研究。试验结果表明，长粒黑豆品种与已知抗病基因的Ｐｅｋｉｎｇ含有相同的抗病基因，哈尔滨小黑豆与ＰＩ９０７６３含有相同的基因，小粒黑豆比ＰＩ９０７６３多含抗大豆胞囊线虫１４号小种的基因，磨石黑豆比ＰＩ８８７８８缺少抗线虫１４号小种的基因，连毛会仅会有抗线虫３号生理小种的基因。
The biological intergeneric method was used to study the interaction between Harbin black bean, long-grain black bean, small black bean, grindstone black bean and black hairy black bean and cyst nematode beans, physiological races 2,3,4,5,9,12 and 14 The relationship was studied. The results showed that the long-grain black soybean had the same resistance gene as Peking with known resistance genes, Harbin black bean had the same gene with PI90763, and the small black bean had more genes than the PI90763 resistant to Soybean cyst nematode 14 , The grindstone black bean lacks a gene that is resistant to the nematode 14 than PI88788, and the bristles will only have a resistance to the nematode 3 racial gene.
