求翻译：在育种实践中借助分子标记对目标性状的基因型进行选择称为标记辅助选择(Marker- Assisted Selection，MAS)，这是分子标记在育种应用中最主要的方面。是什么意思？

With molecular markers in breeding practice on the genotype of the target trait called marker-assisted selection (marker-assisted selection, mas), which is the most important aspects of molecular markers in breeding applications.

In the breeding practices of the target marks with elements of the genotype to select letters referred to as the tag (Marker - select Secondary Assisted Selection MAS) and molecular markers, and this is in the application in breeding the most important aspects.
