设施内杏梅、李及杏远缘杂交试验

Report of Distant Hybridization about Armeniaca,Apricot and Plum in Green House

试验以设施内杏梅、李及杏等3种核果类果树为试材,进行了远缘杂交试验。研究结果表明:①母本的不同花期授粉,坐果率差异很大,铃铛花期授粉坐果率显著地高于初花期授粉坐果率。②不同杂交组合的坐果率差异显著,在同一母本(杏梅)的杂交组合中,以金太阳杏作父本的杂交组合坐果率最高,为23.8%。以平顶香李作父本的杂交组合坐果率最低,为7.1%。③杏(♂)×李(♀)组合虽然杂交亲和性较高,但杂种败育率也很高。杏(♂)×杏梅(♀)组合虽然杂交亲和性较低,但杂种败育率也很低。

The experiment of distant hybridization has been conducted among three varieties of armeniaca, plum and apri- cot. The result showed： （1） Setting percentage was different in different pollination stage and obviously higher in balloon stage than in early blooming stage. （2） Setting percentage was different in different cross-combinations. In all cross-combinations with the same female parent（armeniaca）, the ones with apricot variety Jin tai yang as male parent had the highest setting percentage. QBoth cross-compatibility and embryo degeneration of hybrids in plums× apricots were higher, but lower in armeniacas×apricots. A set of byhid individuals had been obtained from this experiment.
