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。
The back-cross results of heterozygote F1 with its parents suggested that the separation of progenies F2 ( SR × S ♂ and RS × R ♂) was consistent with Mendel's single gene inheritance model. F1杂合子与亲本的回交表明其后代F2(SR×S♂和RS×R♂)的分离符合孟德尔单基因遗传模型。
A strategy based on the development of multi-parental introgression lines, together with target trait screening and molecular marker survey, was used to map QTLs and develop back-cross deried breeding lines. 通过大规模回交构建多亲本导入系群体,结合目标性状筛选和分子标记鉴定,在定位抗旱相关QTL的同时培育回交改良株系,可以通过株系间杂交实现异源抗旱QTL的有效聚合。
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。
