Its fruit was oval in shape, with a single fruit weight of 120−180 g and light-pink peel. The flesh was white, soft, tender and juicy. The content of total soluble solid was 9.8%, the total sugar content was 6.8 g·hg−1, the content of vitamin C was 129 mg·hg−1, and the titratable acid content was 3.37 g·kg−1. It had rich aroma, unique flavor and excellent quality. This variety had early fruiting, high yield and stable yield, and could flower and bear fruit when planted in the same year. The yield of the 4-year-old trees was more than 54000 kg·hm−2.
