Abstract:

Flower Bulbs have high ornamental value and market demands. Improving their quality and cultivation characteristics by breeding method has become a core competitiveness in the international flower market. This paper summarized the current key breeding objectives of flower bulbs represented by lily;  expounded the development and application of hybridization, mutation breeding and molecular breeding, etc. technology in the process of developing new varieties, combining with the history and recent research progresses of lily breeding. The result of analysis showed that the breeding objectives were improved from increasing their ornamental value to cultivation characteristics and postharvest quality, and the breeding method tends to combine the modern technology as molecular breeding with the traditional ones. Domestic flower bulbs breeders had better to fully utilize the peculiar germplasm resources of flower bulbs, to develop new varieties adapted to our own ecological conditions, and to establish a breeding system for superior varieties as earlier as possible.

Key words: flower bulbs, lily, hybridization breeding, mutation breeding, molecular breeding

摘要：

球根花卉具有极高的观赏价值和市场需求。通过育种研究提高球根花卉的品质和栽培性状,已成为国际花卉市场竞争的核心。总结了以百合为代表的球根花卉当前的重点育种目标,结合百合的育种历史和近期育种研究进展,对杂交育种、突变育种和分子育种等技术在新品种培育过程中的发展和应用进行了阐述。分析得出,球根花卉的育种目标逐渐从提高观赏性转向重视栽培和采收性状,育种方法趋向于现代分子育种技术和传统育种手段结合。国内球根花卉育种工作者有待充分利用我国特有种质资源,进行适应我国生境的新品种选育工作,早日建立起优良品种培育的技术体系。
