摘　　要：采用植物组培变异筛选技术,经多年系统株选,在中山过山香品种组培苗田间变异株系中选育出优质、高抗型粉蕉新品系"中科红粉"。在广东省中山市、广州市、肇庆市的多个香蕉主产区进行中科红粉品系区试,田间种植结果为高抗枯萎病,其种性基本特征为株高3.0 m,叶片尖挺,叶柄基部紫红色,果指排列整齐,梳把稍密,单株产量17～20 kg,全生育期为14个月。中科红粉新品系土壤适应强,受肥中等,是传统优势香蕉产业区域的优选高抗型新品系。A new banana clone Zhongkehongfen with superior quality and high resistance was selected out using the plant selection technique through variation in tissue culture.Regional experiments on Zhongkehongfen clone in many banana production areas in Zhongshan,Guangzhou,Zhaoqing showed that the clone was highly resistant to wilt disease.The clone had the characteristics of plant height of 3.0 m,long and hard leaves,neat fruits and slightly compact comb.The yield was 17～20 kg/plant.Overall production period of the clone was 14 months.Zhongkehongfen clone was highly adaptable to various soils.It is a new clone of highly resistant type for the traditional banana production areas.
