摘要
通过四个对东北大豆花叶病毒３号株系（１７３强毒株）的感×抗杂交组合的Ｆ１、Ｆ２和回交ＢＣ１群体的成株抗性分析，明确了四个创新抗源的遗传特点及其应用价值。哈９１Ｒ３－１８２、哈９１Ｒ３－１８８，其抗性是由两对互补隐性基因控制的，Ｆ２抗感分离比例为７∶９；哈９１Ｒ３－３０１，哈９１Ｒ３－３１０其成株抗性是由两对互补显性基因控制的，Ｆ２代抗感分离比例为９∶７，这四份种质可作为东北地区抗ＳＭＶ育种的理想抗源。
Heredity charactersistics and utiliration value of 4 parents resistant to Soybean Mosaic Virus (SMV) had been revealed by and analysis of F 1、F 2 and BC 1 population from the crosses among them. Ha 91R 3-182, Ha 91R 3-188 had two recessive complamentary genes resistant to No. Ⅲ strain of SMV. The segregation ratio in F 2 between resistant and susceptible was 7∶9. Ha 91R 3-310 had two dominant complemtary genes contralling resistance to No. Ⅲ strain of SMV, the segregation ratio in F 2 between resistant and susceptible was 9∶7. The four soybean germplasm are highly resistant germplasms for breeding of soybean resistance to SMV in Northeast areas.
