汴 grind on the 2nd watermelon is used in 1975 as the mother of walnut pattern, Asahi parent cross hybrid made. After nearly ten years of optimal cultivation, the genetic type was basically stable, and the botany traits were consistent. In order to further improve the quality, since 1980, it was backcrossed again with the Japanese cultivar Asahi-Dabai. The sugar content increased from 9% at the beginning of breeding to 11%. After three years of self-selection and three consecutive years of district test and More demonstration, sugar content remained at about 11%. Users agree that the varieties of high yield and quality, strong resistance, storage and transportation, significant economic benefits. First, the characteristics, characteristics Strong growth potential of plants, leaf palm has a profound, Section 7 to 8 is the child, monoecious allspice, less easy to branch
