One of the cultivars cultivated by Jiangsu Provincial Academy of Agricultural Sciences, Su-mei No.1 watermelon has been very popular since its popularization. The area now planted accounts for 70% of the total area of watermelon in Nanjing and 60% in Jiangsu Province, becoming the original varieties of the province and the municipality.

First, the purification and rejuvenation Rejuvenation method is self bagging bagging, planting a single melon, hybrid breeding in different places, that is, 2 years 2 self-bred mixed law. (A) the principle of bagging self-purification Watermelon is cross-pollination crops, prone to days
