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(biāo)記輔助選擇（MAS）因其對(duì)目標(biāo)基因的快速準(zhǔn)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(biāo)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(duì)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(guò)與良種的回交和品系內(nèi)選育進(jìn)行的品種改良。
