Abstract:

Fusarium wilt is a global destructive disease for banana production, which can’t be effectively controlled. Breeding resistant varieties is one of the important measures to control it. The author conducted a plot experiment for three banana resistant varieties on the biological characteristics, agronomic traits, yield and morbidity. There were no big differences between ‘Nantian Huang’ and ‘Guikang 2’ varieties, but there were significant differences between ‘Zhongjiao 9’ and others. The growth period for ‘Nantian Huang’ and ‘Guikang 2’ was 383 and 393 days, separately, but the growth period for ‘Zhongjiao 9’ was 447 days. The agronomic traits for ‘Nantian Huang’ and ‘Guikang 2’ were not different obviously, and the short stalk, banana pesudostem height for the two was 285 and 298 cm separately. The average banana pesudostem for ‘Zhongjiao 9’ was 340 cm. The fruit index for ‘Nantian Huang’ and ‘Guikang 2’ was 21, and the fruit shape was moderate, which was similar to that of Banana Brazil. The fruit index was 16 for ‘Zhongjiao 9’, and the fruit shape was straighter and larger. The yield for ‘Zhongjia 9’ was the highest, which was 24.9 kg/bunch weight, and the yield for ‘Nantian Huang’ and ‘Guikang 2’ was 23.5 and 23.2 kg/bunch weight separately. The incidence rate of Fusarium wilt for ‘Nantian Huang’, ‘Guikang 2’ and ‘Zhongjiao 9’ was 0, 0.6% and 4.7% separately. In summary, ‘Nantian Huang’ and ‘Guikang 2’ are more suitable as Banana Fusarium wilt disease-resistant varieties, and more suitable for large-scale demonstration work for the future.
