| Abstract: In order to screen out new watermelon varieties suitable for planting in open field in western Zhejiang, four new watermelon varieties were introduced and 'Zaojia 8424' was used as control to carry out variety comparison test. By observing the growth characteristics of sowing, transplanting, tendril extension, fruit setting and maturity period, and the characters such as plant height, inter node length and node position of the first female flower, the fruit shape index, uniformity and yield, and the comprehensive agronomic characters of different varieties in the field were identified and evaluated. The results showed that 'Yongmi No.6' showed the best comprehensive characters, the central sugar contents and side sugar content reached 11.8% and 8.6%, respectively, which were significantly higher than those of other tested varieties and the control group, and the yield was higher with 2 872 kg per 667 m2, which was suitable for popularization and planting in the field in western Zhejiang. |
