Evaluation of 5 banana varieties for resistance to Fusarium wilt ( Fusarium oxysporum f.sp.cubense )
摘要
Abstract
[Objective]Five banana varieties were evaluated for resistance to different physiological races of Fusarium wilt in order to screen and extend elite resistant varieties of banana. [ Method ]Fusarium wild resistance in five banana varieties, viz., Fenza 1 Hainan KKF, Hainan KK1, Hainan KK2 and Xinbeijiao, was assessed to physiological races No.1 (FOC35) and No.4 (FOCTL02) at seedling stage of potting culture and whole growth duration in field. [ Result ]Two Musa ABB group Fenjiao varieties Fenza 1 and Hainan KKF exhibited highly resistance to FOC35 compared to local variety Jin-fen 1 (moderately resistance) in Guangxi. Out of the 3 banana varieties, Hainan KK2 was highly resistant to FOCTL02, and Hainan KKI and Xinbeijiao were resistant to FOCTL02. The resistance of all the 3 tested banana varieties to FOCTL02 was better than that of the local banana variety Williams B6 (sensitive). [ Conclusion ]It is concluded that all Eve varieties may be extended for commercial cultivation due to great resistance to Fusarium wilt.关键词
