Abstract
Pingguo pear and other cultivars were used as materials,identified pollen fertility and pollination compatibility by pollen test,self-pollination and cross-pollination experiment.The results showed that five cultivars such as Yanbiandaxiangshui,Yanbianxiao xiangshui,sport of xiaoxiangshui,Jianba pear,Yanbianmingyue pear are male sterility.In eight self-pollination combination of this study,seven combination are self incompatibility.Pingboxiang is self compatibility,and it's bearing rate of self-pollination of inflorescences and flower are 100% and 50%,respectively.In 35 hybridization combination,bearing rate of flower of are higher than 30% in thirty-one combination,showed cross compatibility.
