Developing of Bolting-resistant Xinlimei Radish Inbred Line'BR-MTH02'
摘要
Abstract
To develop bolting-resistant Xinlimei radish germplasm,the Japanese bolting-resistant cultivar'Ninengo'was used as the donor parent and the Chinese Xinlimei radish inbred line'MTH02'as the recurrent parent.Through backcrossing,selfing,molecular marker-assisted selection(MAS)and field trait evaluation,the bolting-resistant gene was successfully introgressed into the Xinlimei radish,resulting in the creation of the bolting-resistant line'BR-MTH02'.Compared to the recurrent parent,'BR-MTH02'exhibited a delayed bolting and flowering time 19.82 and 22.77 days,respectively,while retaining key agronomic traits of the Xinlimei radish,such as leaf shape,root shape,and red flesh.This study realized the practical application of the RsFLC2 molecular marker in breeding,providing a reference for the subsequent development of bolt-resistant germplasm.关键词
