观赏芍药杂交育种研究进展

Research Progress on the Crossbreeding of Ornamental Herbaceous Peony

芍药是中国乃至世界的著名观赏花卉。芍药属种质资源分布极其广泛,遗传性状变异丰富。利用属内丰富的种质资源进行组内和组间杂交育种是芍药新品种培育的主要途径。该研究简要介绍了用于芍药杂交育种的芍药属牡丹组和芍药组种质资源的主要特性,重点归纳了利用芍药属的不同种源、不同品种群亲本开展芍药近缘和远缘杂交育种的主要成果,并对今后杂交育种过程中种质资源利用、杂交障碍克服、繁育体系建立以及生物技术应用等方面进行了分析和展望。

Herbaceous peony is a famous ornamental flower in China and even in the world.Paeonia germplasm resources,with abundant variations in genetic traits,are widely distributed.Crossbreeding(intrasection and intersection)is the main way to cultivate new varieties of herbaceous peony by utilizing abundant wild and cultivated germplasm resources of Paeonia.In this study,the main characteristics of sect.Moutan and sect.Paeonia germplasm resources were briefly introduced.The progress of crossbreeding of herbaceous peony was summarized according to different cultivar groups produced by different provenances.On this basis,the utilization of germplasm resources,the overcoming cross barriers,the establishment of breeding system and the application of molecular biotechnology in the future crossbreeding were briefly analyzed and prospected.
