摘　　要：随着我国园林绿化市场的持续升温 ,园林植物育种领域的研究不断得到重视 ,在传统育种技术的基础上 ,以现代生物技术、航天和离子注入诱变育种为核心的高新技术育种得到较大程度的发展。本文阐述了基因工程和细胞工程技术在园林植物株型和花型、花色和香味、生长发育、延缓衰老、抗病虫、抗逆境等方面的研究现状 ;综述了航天育种和离子注入育种等高新技术的研究基础 ,及其在园林植物种质创新领域的研究进展 ;并介绍了国内有关研究单位的一些相关研究情况。分析了园林植物育种技术的发展趋势 ,并重点对园林植物现代生物技术、航天和离子注入育种作了展望。With the development on landscape market, research on breeding of landscape and ornamental plants was developed fast. Base on the traditional breeding techniques, breeding of new and high-techs in landscape and ornamental plants, including modern biotechnology, space mutation breeding, low energy ion breeding were reviewed. Mainly, current research advances were discussed on genetic and cell engineering technologies exploiting in plant stature and flower shape, color and fragrance, growth and development, life lengthening, pest and disease resistance, and adverse circumstance tolerance. Research situation and advances on breeding of space mutation and low energy ion,and relation techniques used for bring forth new germplasms of landscape and ornamental plants were reviewed. Research advances of the related departments at home were also introduced. The prospect was made for breeding techniques of landscape and ornamental plants, focused on development breeding of modern biotechnology, space mutation and low energy ion for landscape and ornamental plants.
