利用抗灰斑病的抗源与感灰斑病的品种(品系)配制组合,选育出高抗灰斑病、广谱抗性好且抗8个生理小种的优良品系合交84-1081和合交87-1087。将此二品系用作杂交亲本,已获得一批杂种优势强、综合性状好、抗性好的品系,因而认为,合交84-1081、合交87-1087是抗灰斑病的优良新抗源。
The resistant and gray rust resistant cultivars (lines) with resistance to Cercospora sojina were formulated and bred, and the excellent lines with high resistance to Cercospora sojae, broad spectrum resistance and resistance to 8 physiological races were bred 84-1081 And co-87-1087. Using these two lines as hybrid parents, a number of lines with strong heterosis, good comprehensive characters and good resistance were obtained. Therefore, it was concluded that the combination of 84-1081 and 87-1087 was an excellent new anti-squamous resistance source.
