香蕉枯萎病己成为香蕉的毁灭性病害。该病属于土传性病害,扩散蔓延速度快,难于进行生物控制、药物防治及轮作、浸田等常用防治方法的防治。因此,防治香蕉枯萎病的最佳方法是进行香蕉遗传改良,培育抗病品种。选用从 INIBAP[(International Network for the Improvement of Bnana and Plantain,国际香(大)蕉改良网络)]引进的42份香蕉种质资源,采用伤根侵染法,用含2×106个孢子/L的香蕉枯萎病1号和4号小种菌液分别对42份香蕉幼苗进行处理,筛选抗香蕉枯萎病种质。结果表明：在侵染1号小种时,7份材料表现高感,13份感病,22份中抗,无高抗；在侵染4号小种时,25份材料表现高感,12份感病,5份中抗,无高抗。综合分析显示, M11和 M25对枯萎病1号和4号小种均表现中抗。

Banana fusarium wilt has become a devastating disease of bananas. The disease is a soil borne disease, spread fast, particularly difficult to control, which include biological control, drug control, rotation and leaching field. Therefore, the fundamental way to control banana fusarium wilt is genetic improvement, breeding disease resistant varieties. This paper selected 42 copies of banana germplasm resources which introduced from INIBAP (International Network for the Improvement of Bnana and Plantain), using method of root wound infection, treated the banana seedlings with fusarium wilt disease of No.1 and No. 4 physiological races which containing 2 ×106 spores /L respectively, to assessed the resistance to fusarium wilt disease. The results showed that: 7 accessions exhibited highly susceptible to physiological races No.1 of fusarium wilt disease, 13 accessions exhibited susceptible, 22 accessions exhibited intermediate resistance, no highly resistance. On the 0ther hand, 25 accessions exhibited highly susceptible to physiological races No.4 of fusarium wilt disease, 12 accessions exhibited susceptible, 5 accessions exhibited intermediate resistance, no highly resistance. Comprehensive analysis, M11 and M25 exhibited intermediate resistance both on fusarium wilt disease of No. 1 and No. 4 physiological races.
