摘　　要：紫金粉玉是由优良红花品系08-1-N-5与早熟大果白花品系09-8-S-9杂交选育出的早熟红花草莓新品种。花色粉红,果实圆锥形,平均单果质量16.85 g,果面红色、平整。果实风味酸甜,香气佳,全年平均可溶性固形物含量(w)10.05%,果实硬度高,为2.17 kg·cm^(-2)。在江苏南京地区,9月上旬定植,11月下旬成熟,抗炭疽病、白粉病和蚜虫等,连续开花结实性强,产量达21.34 t·hm^(-2),鲜食观赏兼用。适合在长江流域草莓产区及气候条件相似的地区设施观赏化栽培。Zijin Fenyu is a new early ripening strawberry cultivar with red flower.The seeding was derived from a cross between 08-1-N-5 and 09-8-S-9 at experimental field.It was initially selected in2014 for its pink flower,early ripening,and good taste.Through artificial hybridization pollination,918 hybrid seeds was got in 2013.After regional adaptability testing at five sites(including Lishui,Jurong,Rugao,Donghai and Yixing),2015 to 2017,it was finally selected in May 2017.The plant growth of this cultivar is moderate and the growth habit of the plant is semi-upright.In January,the plant height is12.8 cm and the crown diameter is 32.8 cm and 25.4 cm.The leaves are elliptic with medium green in color.The leaf length is 7.8-8.0 cm and the leaf width is 7.2 cm.The petiole length is 10.8 cm.Hermaphrodite flowers are pink and the corolla diameter is 3.1 cm.The average inflorescence length is15.8 cm.The number of flowers per inflorescence is 9-12.The fruit is mainly conical with slightly red peel and shine surface.The flesh is light red with intense aroma.The average fruit weight is 16.85 g.The fruit tastes sweet and sour.The content of soluble solids is 10.05%.The fruit firmness is much better with 2.17 kg·cm^(-2).The plantlets usually plant in early September,and the fruits ripen in late November in the protected culture of Nanjing,Jiangsu.The ability of continuous flowering and fruiting is strong and the yield is up to 21.34 t·hm^(-2).It is resistant to anthracnose,powdery mildew,aphids,etc.This cultivar is suitable for fresh food and ornamental.It can be ornamental cultivated in strawberry producing areas of the Yangtze River Basin and areas with similar climatic conditions.Because this cultivar has higher yield,it is needed to apply enough base-fertilizes and disease-free strong seedlings.According to the growth of the plant,fertilizer supplement should be timely and appropriate.
