back cross breeding

基本解释

Molecular marker assisted selection(MAS) can provide a rapid, accurate, and efficient tool for selecting target genes in back cross breeding.
分子标记辅助选择（MAS）因其对目标基因的快速准确选择为回交育种提供有效工具。
It is possible to manipulate and to introgrese target genes in crops by the selection based on molecular markers together with classical back-cross breeding method.
分子标记与育种结合，可能以较高精度和速度鉴定，转移和整合目的基因，也可用于以对数量性状的操作。
Various approaches have been used to improve the performance of adapted indigenous stock, including cross-breeding and upgrading through back-crossing with improved breeds, and within-line selection.
已有多种方法被用于提高地方良种的性能，包括杂交育种，以及通过与良种的回交和品系内选育进行的品种改良。
