‘Zhongjiao No. 9’, a new banana variety with high resistance to ‘fusarium wilt No. 4’, was introduced and transplanted in different dates from January to October in Nanning, Guangxi, China, and its growth characteristics, yield and quality were observed in order to provide references for the selection of disease-resistant varieties in Guangxi. ‘Guijiao No. 1’ was used as the control, a traditional variety in Guangxi, and the plant growth characteristics, yield and fruit quality of ‘Zhongjiao No. 9’ and ‘Guijiao No. 1’ under different transplanting dates were determined. The results showed that: ‘Zhongjiao No. 9’ had a greater yield advantage than ‘Guijiao No. 1’. The average yield of ‘Zhongjiao No. 9’ was 16.2% higher than that of ‘Guijiao No. 1’. ‘Zhongjiao No. 9’ had higher yield under transplanting date of Feb. 15stand Oct. 1st. The growth period of ‘Zhongjiao No. 9’ under different transplanting dates was 140~181 d longer than that of ‘Guijiao No. 1’, and its growth period under summer and autumn planting was 161 d longer than that under winter and spring planting on average, mainly due to bud squaring delayed. Besides, compared with ‘Guijiao No. 1’, ‘Zhongjiao No. 9’ had longer growth period, later bud squaring, higher leaf photosynthetic potential and leaf area index before budding, which were the basis of its biomass and yield formation. In terms of quality, the content of total sugar and titratable acid of ‘Zhongjiao No. 9’ under transplanting dates of Jan. 1st was 29.0% and 63.0% higher than that of ‘Guijiao No. 1’ after fruit ripening, respectively. The fat content of ‘Zhongjiao No. 9’ was significantly lower than that of ‘Guijiao No. 1’. Therefore, the fruit of ‘Zhongjiao No. 9’ after ripening showed high sugar, acid and low fat. In conclusion, ‘Zhongjiao No. 9’ had a certain yield advantage in Guangxi, but its growth period was longer and the bud was later than ‘Guijiao No. 1’. Transplanting on Feb. 15st in winter and spring could achieve high yield and shorten the growth period for ‘Zhongjiao No. 9’, but it is still necessary to further observe its comprehensive performance in the disease area.

Key words: transplanting date, ‘Zhongjiao No. 9’, yield, quality, banana fusarium wilt resistant variety
