Breeding report of a new strawberry cultivar with red flower Zijin Fenyu

Abstract:Zijin Fenyu is a new early ripening strawberry cultivar with red flower. The seeding was de- rived from a cross between 08-1-N-5 and 09-8-S-9 at experimental field. It was initially selected in 2014 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 is 12.8 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. Her- maphrodite flowers are pink and the corolla diameter is 3.1 cm. The average inflorescence length is 15.8 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 bet- ter with 2.17 kg·cm-2. The plantlets usually plant in early September, and the fruits ripen in late Novem- ber 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 pro- ducing areas of the Yangtze River Basin and areas with similar climatic conditions. Because this culti- var has higher yield, it is needed to apply enough base-fertilizes and disease-free strong seedlings. Ac- cording to the growth of the plant, fertilizer supplement should be timely and appropriate.
