用大豆胞囊线虫（Ｈｅｔｅｒｏｄｅｒａｇｌｙｃｉｎｅｓ）３号生理小种接种抗病品种小粒黑豆、连毛会黑豆、磨石黑豆与感病品种铁丰２４号、铁丰１８号、开育１０号杂交组合，根据Ｆ２代分析结果，小粒黑豆在铁丰２４号背景下表现出有两对抗病基因，在开育１０号的背景下由４对显性抗病基因控制对３号小种的抗性，磨石黑豆在铁丰２４号背景下有两对隐性抗病基因，铁丰１８号×连毛会黑豆组合Ｆ２代分离表现为三对基因的互补作用。
Heteroderalycines No. 3 physiological races were used to inoculate the resistant varieties of small black bean, black hairy black bean, grindstone black bean and susceptible variety Tiefeng 24 and Tiefeng 18, F2 generation analysis showed that the black pea seeds showed two resistance genes in the background of Tiefeng 24 and the resistance to the third seed was controlled by 4 pairs of dominant resistance genes in the setting of No.10 There were two pairs of recessive disease resistance genes in Shihei bean in the background of Tiefeng 24, and F2 generation in Tiefeng 18 × Lian Maohui black bean showed the complementarity of the three pairs of genes.
