Abstract:

To improve the fruit quality and the calyx-abscission rate of ‘Yulu Xiangli’ pear, screen out suitable pollination varieties, ‘Huangguan’, ‘Xueqing’, ‘Cuiyu’, ‘Zaosu’ and ‘Pingguoli’ were selected as pollination varieties, the main indexes such as fruit-setting rate, and fruit internal and external qualities of different pollination combinations were measured by artificial pollination with the healthy growing and fruiting ‘Yulu Xiangli’ pear as the female parent. The results showed that the artificial pollution of ‘Huangguan’ for ‘Yulu Xiangli’ pear had the highest fruit-setting rate, the smallest fruit shape index and skewness, the largest fruit size, the most correct fruit shape, high soluble solids’ content, and superior internal and external qualities to other pollination varieties. In general, ‘Huangguan’ is the most suitable pollination variety for ‘Yulu Xiangli’ pear in Jingtai area.

Key words: ‘Yulu Xiangli’ pear, artificial pollination, fruit shape, fruit-setting rate, fruit quality
