Abstract:

Watermelon Fusarium wilt is a soil-borne disease caused by Fusarium oxysporum, which has severely limited the sustainable development of watermelon production in the world. At present, there are no effective bactericides to prevent and control Fusarium wilt. Breeding for disease resistant watermelon new varieties is the most economical and effective way to solve this problem. Moreover, in the last ten years, because of the rapid application of intensive facility cultivation in China, the traditional rotation cultivation of watermelon has been extremely difficult, which caused Fusarium wilt to be more and more serious. So new watermelon varieties with disease resistance, good quality and early-middle maturity suitable for the facility cultivation and could meet the demand of modern market are in urgent need. ???Shenxuan 958??? is a new watermelon hybrid cultivar with resistance to Fusarium wilt and good quality, which is developed by using the inbred line W26-5-8 as female parent and the inbred line V16-3-7 as male parent. This cultivar grows vigorously and tolerant to low temperature and weak light, and it is easy fruit-setting under the sloppy and weak light weather of southern China. ???Shenxuan 958??? shows earlymiddle maturity, harvested about 35 days after flowering, and fruit weight is about 5.5 kg, the general yield is about 52.5 t/hm2. The fruit shape of ???Shenxuan 958??? is ellipse, and the skin is green with dark green middle strips. The flesh is dark pink color, the center soluble sugar contents is over 12%, the side soluble sugar contents is over 8.5%, and with more juice and delicate. The fruit is tolerance to transportation and storage, and this new cultivar is with wide adaptation. It is suitable for cultivation in open or protected facilities in southern or northern China. The extension area has been over 746.6 hm2 in Jiangsu, Zhejiang, Shanghai and Anhui province of China. Recent Publications: 1. Wang H B et al.
