摘要/Abstract

摘要：

利用6个苹果杂交群体（‘蜜脆’×‘瑞阳’、‘藤牧1号’×‘嘎啦’、‘富士’×‘粉红女士’、‘瑞阳’×‘爱妃’、‘富士’×‘新疆野苹果’和‘秦冠’×‘蜜脆’）对ERF17、MYB1、ERF4、ACS1、ACO1、ACS3a866分子标记进行验证。通过基因型与果实表型（包括果皮叶绿素含量、着色度、果实硬度）关联分析标记与性状的相关性。结果显示，ERF17标记在多数群体中能准确预测叶绿素含量，但在‘藤牧1号’×‘嘎啦’群体中不显著；MYB1标记对果皮是否为红色的预测准确率高达92.05%；ERF4、ACS1和ACS3a866在果实硬度预测中表现出较高的准确性，但标记间存在互作效应。

Abstract:

In six apple hybrid progenies（‘Honeycrisp’×‘Ruiyang’，‘Mato 1’×‘Gala’，‘Fuji’×‘Pink Lady’，‘Ruiyang’×‘Envy’，‘Fuji’×‘Malus sieversii’，and‘Qinguan’×‘Honeycrisp’），six molecular markers（ERF17，MYB1，ERF4，ACS1，ACO1 and ACS3a866）were validated. The correlation between markers and traits was analyzed by associating genotypes with fruit phenotypes（including peel chlorophyll content，coloration degree，and fruit firmness）. The results showed that the ERF17 marker accurately predicted chlorophyll content in most progenies，but it was not significant in the ‘Mato 1’×‘Gala’progeny. The MYB1 marker achieved a high prediction accuracy of 92.05% for whether the peel is red. ERF4，ACS1，and ACS3a866 showed high accuracy in predicting fruit firmness，but there were interactions among the markers.

Key words: apple, molecular marker, peel degreening, firmness, phenotypic validation, epistasis
