Abstract:

Fusarium wilt is the most destructive disease of banana productionwhich caused by Fusarium oxysporum f. sp. cubenseFoc. Foc tropical race 4Foc TR4is the most pathogenic type. Rapid and accurate evaluation system for resistance of banana to Foc TR4 is essential for both basic research and banana breeding. In this studywe compared the incubation effects of immersing root method and improved drenching root methodand the detection effectives of two primers. The results showed that the resistance of banana could be evaluated accurately by using improved immersing root method with concentration of 1 × 104. For molecular detectioncorms with index of disease up to scale 3 could be amplified by first PCR using the special primers Foc TR4 F/Rand all diseased bubs of ID scale up to 1 could be de detected by Sub-PCR.

Key words: banana, Fusarium wilt, Fusarium oxysporum f. sp. cubense tropical race 4(Foc TR4), resistance evaluation, molecular detection
