| 摘 要： | 本系统地介绍了近年来有关标记辅助选择改良数量性状的研究进展，主要包括标记辅助回交、指数选择与最佳线性无偏预测的理论和应用研究概况。理论与计算机模拟表明标记辅助选择比常规表型选择更有效，但在实际育种中并不理想。同时本还就当前标记辅助选择存在的问题和前景进行了讨论。

| Abstract: | Recent advances on marker-assisted selection (MAS) in the improvement of quantitative traits are reviewed. These include theoretical researches and applications of marker-assisted backcrossing, index selection, and best linear unbiased prediction (BLUP) in animal and plant breeding. Theoretical and simulation studies show that marker-assisted selection can substantially increase the efficiency of selection in comparison to phenotypic selection, but is not yet a proven technology. Problems and prospects in MAS are also discussed. |
