Abstract: ''Heibite'' was a new diploid watermelon cultivar bred by crossing inbred line W10-217 as female parent and inbred line W09-27 as male parent. Its whole growth period was 92.0-95.0 days with 33.0-35.0 days of the fruit development period. It had slightly stronger plant growth potential, the first female flower was in the 4th7th node, and the female flower was 5-6 nodes apart. The fruit was long and oval, and the pericarp was dark green, with thick black stripes and a thickness of about 1.2 cm. The flesh was red, the flesh was fine and crisp without residue, and the soluble solid content in the center was about 12%. The weight was about 5 kg per melon, and the yield was as high as 2 805.6 kg per 667 m2 . The disease resistance was strong. It was suitable for planting in Hainan and Guangxi. At present, its promotion area had been up to 1 500 hm2 .
