back cross breeding

基本解釋

Molecular marker assisted selection(MAS) can provide a rapid, accurate, and efficient tool for selecting target genes in back cross breeding.
分子標記輔助選擇（MAS）因其對目標基因的快速準確選擇為回交育種提供有效工具。
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.
分子標記與育種結(jié)合，可能以較高精度和速度鑒定，轉(zhuǎn)移和整合目的基因，也可用于以對數(shù)量性狀的操作。
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.
已有多種方法被用于提高地方良種的性能，包括雜交育種，以及通過與良種的回交和品系內(nèi)選育進行的品種改良。
