航天诱变水稻对叶瘟和穗瘟的抗性鉴定

Identification of rice resistance against leaf blast and seeding blast disease in the test of spaceflight mutagenesis

采用蒙古稻旱晚播活体菌株接种法 ,对JB-1号返回式卫星搭载回的 12个稳定的水稻突变体作了稻瘟病抗性鉴定 ,结果明确 ,航天诱变水稻材料 971-5、974 -4、974 -5均抗叶瘟和穗瘟。

Twelve stable mutant breeds carried by No. JB-1 retrievable satellite, were identified by the living strain inoculate method for MengGu rice that was sowed late seasonally in upland field. Results showed the breeds which resist leaf blast and seeding blast were 971-5, 974-4, 974-5.
