通过对800余份野生大豆对大豆花叶病毒抗性的接种鉴定,总结出适合于野生大豆抗花叶病毒病的鉴定方法。筛选出植株抗病材料2份,中抗材料11份,其余的材料都表现中等以上的感病。植株抗性与种籽传病率有一定关系但不呈正相关,选出5份种籽传病率稳定表现为零的材料。没有发现能抗大豆花叶病毒东北三个株系的材料。探讨了野生条件下不发或很少发生花叶病毒病的原因。
Through the identification of more than 800 wild soybean soybean mosaic virus resistance inoculation, the identification method suitable for wild soybean anti-mosaic virus disease was summarized. Screening 2 parts of the plant disease-resistant material, 11 parts of the anti-resistant material, the rest of the material showed moderate or more susceptible. There was a certain relationship between plant resistance and seed-borne disease but not a positive correlation. Five materials with stable seed-borne disease rate were selected. No material found to be resistant to the three northeastern strains of soybean mosaic virus. The reasons for the non-occurrence or rare mosaic virus disease in wild conditions were explored.
