蔷薇属分子生物技术研究进展

Recent Advances in Molecular Biotechnology of the Genus Rosa L.

对近20 a来蔷薇属植物分子生物学技术研究取得的进展进行了系统回顾与分析。由于蔷薇属植物基因组高度杂合,分子生物技术成为研究蔷薇属系统进化与遗传多样性的重要手段,现已成功构建二倍体月季和四倍体月季遗传图谱,并在分析重要遗传性状、分离和鉴定基因等方面取得有价值的结果。分子标记辅助育种与常规杂交育种相结合将加速现代月季品种群的育种进程。中国是蔷薇属植物重要分布中心之一,但对其研究和育种与国外还有很大差距,部分工作刚刚开展,本文对我国蔷薇属研究存在的问题和发展方向进行了分析。

Advances in the researches of molecular biotechnology of the genus Rosa L. were reviewed during the last two decades from the aspects of genetic diversity of germplasm, construction of genetic linkage map, inheritance of rose traits and identification of cultivars for roses. China is one of distribution centers of genus Rosa L. , however, there is a wide gap between China and other countries in genetic study and the breeding. Additionally, some problems in the application of molecular markers in genetics and breeding of roses and isolation genes were discussed.
