| 摘 要： | 库尔勒香梨是中国久负盛名的梨果佳品。却存在着果个小、果心大的缺陷。为了传承香梨品质优势，克服其弱点，本课题组于1971年开始香梨为亲本的杂交育种工作。以6个梨的杂交组合、351株实生树为试材，进行了各组合亲本和后代的性状分析，探讨了各主要性状的遗传趋势。结果表明，杂交后代果实形状、肉质遗传倾向于亲本，倾亲率分别为68.09%和51.38%。梨果实大小为数量性状，杂种后代果个分离广泛，杂种后代果实普遍变小，各组合的遗传传递力在68.91%~117.51%之间，平均遗传传递力为93.11%。梨果实可溶性固形物含量呈数量性状遗传，杂种后代分离较广，其组合传递力平均为97.49%。

| Abstract: | Korla pear has been a well-known variety in China for a long time,but it has some defects such as small fruit size and large core.In order to maintain its good quality and overcome its shortcomings,cross breeding using Korla pear as the parent has been carried out since 1971.351 seedlings of 6 pear cross combinations were used for studying the trends of inheritance for the main characters of pear fruit by analyzing the characters of the parents and their progenies.The results showed that the inheritance of ... |
