Introduction experiment and application assessment of two kinds of new banana cultivars resistant to Fusarium wilt

2 new cultivars,banana series of Nongke No.1 and dwarf banana series of Fenza No.1 resistant to Fusarium wilt were introduced.Baxi banana and Guangfen No.1 dwarf banana were chose for comparison respectively.Planting experiments were conducted under three different conditions,the absence of Fusarium wilt history field,the lighter incidence field with former stubble 5% ~10% morbidity of Fusarium wilt and serious illness field with former stubble incidence rate more than 30%.The results showed that Nongke No. 1 was more productive than the contrast under all the three planting conditions,with Fusarium wilt disease morbidity reduced by 59.7% than Baxi banana at most.Yield per plant of Fenza No.1 was low,especially under the condition free of Fusarium wilt history.But in Fusarium wilt history field,it showed higer or the same production per unit area,with blight morbidity reduced by 62.7% than Guangfen No.1 at most.Two cultivars are both suitable for planting in Fusarium wilt area.And some deficiencies can made up through the cultivation regulation measures.
