国内外萱草新品种选育研究进展

Research Progress on Breeding of New Hemerocallis Varieties at Home and Abroad

萱草(Hemerocallis L.)是我国传统的园林植物,因其食药兼顾而具有极高经济价值。中国虽然是萱草属植物自然分布最广的国家,相关研究却落后于国外。目前国内所使用的园艺品种主要依靠国外引进,具备我国自主知识产权的园艺品种相对较少。本文对国内萱草种质资源进行了详细介绍,从花型、花香、花色、花期、抗寒、抗病等不同选育目标的角度,对国内外的新品种选育成果进行综述,重点突出了国内在花期、抗寒新品种的育种成果,同时对新品种选育技术进行了概述,并对国内在萱草新品种选育研究中的问题和展望进行了讨论,以期为萱草新品种选育提供参考依据。

Hemerocallis is a traditional garden plant in China,which has high economic value because it can be used as both food and medicine.Although the natural distribution of Hemerocallis is the largest in china,the related research lags behind foreign countries.At present,the horticultural varieties used in China mainly rely on foreign imports,and hortiaultural varieties with our own intellectual property rights are relatively few.In this paper,the germplasm resources of domestic Hemerocallis were introduced in detail,and the breeding achievements of new Hemerocallis varieties at home and abroad were summarized from the perspectives of different breeding objectives,such as flower shape,flower aroma,flower color,flowering period,cold resistance,disease resistance,etc.The breeding achievements of new Hemerocallis varieties at flowering time and cold resistance at home were highlighted.At the same time,the new breeding technology was summarized,and the problems and prospects in the domestic Hemerocallis breeding were discussed,which aimed to provide reference for the breeding new varieties of Hemerocallis.
