linkage genetic map

This paper summarizes the main reference families and DNA molecular marker's selection, and the research situation of genetic linkage map and its development prospect on sheep.

本文对绵羊的主要参考家系、构建遗传连锁图的分子标记的选择、绵羊的遗传连锁图的研究现状以及展望进行综述。

However, in the construction of genetic linkage map and the use of molecular marker-assisted breeding, it drops behind the other major crops.

然而其在构建遗传连锁图谱及利用分子标记辅助育种方面，明显滞后于其他主要经济作物。

In this study, the average map distance is too large, which requires to be further deepened for building a genetic linkage map of Jute with evenly-distributed markers and high-density sites.

本研究的平均图距还较大，有待于进一步深化，以期构建出一张标记分布均匀，位点密度较高的长果种黄麻遗传连锁图谱。
