以四川优良的中国樱桃栽培和野生种质及欧洲甜樱桃为试材进行杂交，对自交坐果率、杂交亲和性、杂交坐果率进行了调查和分析.结果表明：(1)中国樱桃自交亲和，欧洲甜樱桃自交不亲和；(2)杂交授粉2周后，各杂交组合表现出较高的杂交亲和性，坐果率为57．24~93．03％；5周后，各杂交组合表现出不同程度的杂种败育性，远缘杂交尤为明显；(3)在中国樱桃种内杂交中，以野生种质为父本的杂交坐果率极显著高于以栽培品种为父本的杂交坐果率；而远缘杂交中，以‘红灯’为母本，以中国樱桃栽培品种为父本的杂交坐果率显著高于以中国樱桃野生种质为父本的杂交坐果率；(4)受亲本影响，不同的杂交组合坐果率不同，受父本的影响极显著高于受母本的影响.基于上述结果，该研究进行了初步的分析和讨论.

Hybridization between the excellent Chinese cherry in Sichuan,including wild germplasms and cultivars, and Cerasus avium has been conducted in this study.Selfing set,hybridization affinity and fruit setting percentage were investigated and analysed.The results were listed as follows:(1)There was a high and low self-compatibility in C .pseudocerasus and C .avium ,respectively;(2)Each hybridization combination showed high affinity after two weeks of pollination,with 57.24%-93.03% of hybrid fruit setting.Different levels of embryo degeneration were ob-served among hybrids after five weeks of pollination,especially in the distant hybridization;(3)The fruit setting rate between cultivars and wild germpalsms was significantly higher than between cultivars in interspecific hybridization combinations.While there was an opposite result in distant hybridization,as ‘Hongdeng’the female parent,the fruit setting rate when using cultivars as male parent was higher than as wild germplasms male;(4)Each cross-combina-tion has different setting percentage influenced significantly by the male parent.We conducted a preliminary analysis and discussion on these results.
