Preliminary report on introduction experiment of new banana variety Hongyan 1 in Nanning of Guangxi

Objective]The planting performance of the new banana cultivar Hongyan 1 in Nanning was observed to provide references for enriching the composition of banana cultivars in Guangxi.Method]Introduction experiment of the new banana cultivar Hongyan 1 was carried out in Nanning to observe plant growth characteristics and fruit agronomic characters and measure yield and fruit quality.Feasibility analysis of Hongyan 1 planting in Nanning was conducted.Result]In trophophase,Hongyan 1 plants grew rapidly.In squaring stage,pseudo-stem height was 212.8 cm and base perimeter was 51.0 cm when the number of functional leaf was 15.0 and leaf was 176.2 cm long and 79.3 cm wide.In harvest time,yield per plant was 21.57 kg,converted to 49930.56 kg/ha and fruit number per comb was 17.8 when fruit finger length was 18.1 cm and perimeter was 15.2 cm.The content of soluble sugar was 22.69％,which was 2.18％ higher than that of Guijiao 6,and the content of the titratable acid was 0.36％.The taste of Hongyan 1 was fresh and sweet.Other major agronomic characters and fruit characters did not differ much between the two plants.Conclusion]Hongyan 1 is suitable for planting in Nanning.
