In this paper, we carried out a comparative test of five seedless watermelon cultivars, Zhongnong Wuzi No.1, Green Field, Golden Orchid, Red Lycopene No.2, Shubao in fields. The results showed that, Zhongnong Wuzi No.1 had good comprehensive characters, high yield, regular fruit shape, high fruit-setting rate and good quality, which could be promoted in Xiangshui county and around area. Though the yield of the cultivar Green Field was relatively low, it was early maturing and possessed regular fruit shape, good quality and commodity nature, which could be promoted as an early-maturing cultivar. Compared with seedless watermelon cultivars with black pericarp, the pericarp and fresh of Golden Orchid were distinctive, and it could be promoted as a characteristic seedless watermelon cultivar. As the main cultivar in Xiangshui, Shubao had larger fruit and higher yield, which could be promoted as a late-maturing cultivar. Red Lycopene No.2 was a functional seedless watermelon cultivar with high content of lycopene, but the related quantitative detection wasn't carried out because of the limited testing condition.% 采用田间试验法对中农无籽1号、绿野无籽、金兰无籽、莱卡红无籽2号、暑宝5个无籽西瓜品种进行品比试验。试验结果表明，中农无籽1号植物学综合性状好，产量高，果形整齐，易坐果，品质优，可在响水县及周边地区大面积推广；绿野无籽产量较低，但早熟性好，果实整齐度高，品质优，商品性佳，可作为早熟无籽西瓜品种推广；金兰无籽与黑皮无籽西瓜比，果皮、皮肉都富特色，可作为特色无籽西瓜品种推广；暑宝作为本地区多年的主栽品种，果实较大，产量较高，可作为晚熟品种栽培；莱卡红无籽2号是功能型无籽西瓜品种，高含番茄红素，因本次的试验条件有限，未能做定量测试。
