Abstract:

To speed up the breeding and promotion of new seedless watermelon varieties, the National Seedless Watermelon Research and Production Cooperation Group carried out demonstration experiments of 10 new seedless watermelon varieties in different places in 2020. By evaluating the disease resistance, fruit setting habits and fruit related traits of the tested varieties, we found that the comprehensive performance of the tested varieties was relatively good. Among them, ‘Jinglong-2’and ‘Jinglong-3’ were small fruit varieties. Compared with medium and large fruit types, the single melon of the above two varieties had smaller weight, higher sugar content and thinner peel, and the two varieties were suitable for facility cultivation. Three varieties, including ‘Red Lycopene No.4’, ‘Xuefeng New 2’, and ‘Jinhuami 2108’, had more outstanding resistance to fusarium wilt at 7 different test sites and the overall performance was relatively stable, which presented a certain promotion value, and were recommended for trial planting in a small area first and then promoted in large area. In summary, 5 of the tested varieties in this study have relatively stable performance in 7 provinces across the country, and have outstanding performance in fusarium wilt resistance, fruit setting habits and sugar content, with certain promotion and application value. The study can provide some suggestions for breeding and cultivating of seedless watermelon.
