摘 要：
分离自玉米上的镰刀菌菌株 YM9- 7与分离自棉花上的镰刀菌菌株 MH50进行杂交 ,可以产生大量 4孢子子囊 ( 95%以上 ) ,将 YM9- 7与 MH50的杂交后代与菌株 MH50回交 ,98%的子囊为 8孢子子囊 ,证实孢子噬杀因子在菌株 MH50内存在。这是我国首例报道孢子噬杀因子在我国李瑟组镰刀菌菌株内存在

摘 要：
Spore killer gene (SK k), a genetically abnormal variant in Fusarium section Liseola, was found in this study. More than 95 percent of asci produced by sexual cross of strains YM9 7 from corn and MH50 from cotton contained 4 spores. Typical 8 spore asci (98%) were got when the cultures from the F 1 progenies backcrossed to strain MH50. It was confirmed that strain MH50 contains a spore killer gene (SK k).
