摘　　要：粉杂1号粉蕉(Musa×pradisiaca ABBB)是广粉1号(ABB)×长梗蕉(BB)杂交4倍体抗病品种。该品种高抗Foc 4号生理小种,在重病区株发病率<5%。植株生长势中庸,生长周期一般为14~16个月,新植蕉每666.7 m^(2)产量为1800 kg,高产园平均株产可达20 kg,每666.7 m^(2)产量约3000 kg。成熟果实可溶性固形物含量(w,后同)为25.72%,可滴定酸含量为0.45%,可溶性糖含量为21.06%,还原糖含量为18.31%,维生素C含量为14.46 mg·100g^(-1),风味浓甜微酸,品质优异。Fenza No.1(Musa×pradisiaca ABBB)is a hybrid progeny of Guangfen No.1(ABB)×Musa balbisiana(BB).One seedling plant was obtained in 2000 and after being planted in the field for successive two cycles,the suckers of the plant were used as explants to obtain tissue-cultured plantlets through adventitious bud proliferation.Comparative trial between Fenza No.1 and Guangfen No.1 was conducted in April 2004.It was observed that Fenza No.1 was highly resistant to Fusarium wilt of banana.The multilocation trails were then conducted in Guangdong and Hainan provinces.Compared with Guangfen No.1,Fenza No.1 is relatively higher and characterized by middle vigorous plant,drooping leaves,relatively small canopy breadth and less-developed root system.The pseudostem height of plant crop and ratoon crop are 325 cm and 410 cm,respectively.The pseudostem base girth and middle girth are 76.7 cm and 52.5 cm,respectively.The leaf blade length is 205 cm,leaf blade width is 59 cm,and leaf ratio is 3.47.Both sides of leaf blade base are rounded but asymmetric.The leaf upper surface and lower surface are green in color and dull.The bunch shape is short-cylindrical with compact appearance.The bunch length is 56 cm,and the bunch girth is 96.3 cm.Positioning of fruits on the crown is biseriate and occasionally fused.Fruit shape is basically ellipse and fruit apex is blunt-tipped and there are remains of the dead style and petal.There are no pronounced ridges on the transverse section of the fruit.The average length of finger is 13.6 cm.Immature fruit peel is light green in color,and pulp color before maturity is cream.The fruit peel turns yellow in color and is not adherent to pulp at maturity.Mature fruits are persistent and don’t fall from hands.The majority color of pulp at maturity is cream,while the remnants of the ovules are yellow in color.The texture of flesh is soft and smooth,pulp ratio at maturity is 74.2%,and predominant flavor is pleasant sweet and subacidic with mild aroma.The soluble solid content of fruit is 25.72%,the titra
