Molecular marker development method for late bolting character of leaf mustard, molecular marker and application

The invention provides a molecular marker development method for late bolting character of leaf mustard, a molecular marker and application, and relates to the technical field of molecular marker development. The invention provides application of SSR molecular marker primers in identification of late bolting character related genes of leaf mustard and provides a development method of related molecular markers. The specific molecular marker primers for identifying late bolting of leaf mustard are developed according to a positioning result, and the difference of polymorphic expression of bolting of leaf mustard on marker sites is detected. When the molecular marker primers are used for screening leaf mustard, the percentage of a morphological band in an early bolting group is 17.60%, the percentage of a polymorphic band in a late bolting group is 44.52%, and the polymorphism is good. 本发明提供了一种叶用芥菜晚抽薹性状的分子标记开发方法、分子标记和应用，涉及分子标记开发技术领域。本发明提供了SSR分子标记引物在鉴定叶用芥菜晚抽薹性状相关基因中的应用，并提供了相关分子标记的开发方法，根据定位结果开发鉴定叶用芥菜晚抽薹的特异分子标记引物，检
