| 中文摘要: |
| 紫薇属植物为我国原生植物，在我国已有 1 500 多年的栽培历史。它是优良的夏花木本植物，因其花色艳丽、花期长、可净化空气等优点，被广泛应用于城市园林绿化中。紫薇种质资源极为丰富，全球紫薇属植物约有 60 种，我国占比达 40%。全国及区域性种质调查成果为紫薇的研究打下了良好基础。近年来，各地加大了紫薇新品种培育和引种应用，育种方式以传统育种为主，培育出较多性状优良且市场价值高的新品种。随着育种技术及分子生物学的快速发展，紫薇分子辅助育种相关研究取得了突破性进展。该文从紫薇的分类研究、种质资源现状、育种研究和引种应用等方面进行综述，系统梳理了我国紫薇种质资源情况（包括野生品种 24 种、栽培品种 350 种），探讨了国内外紫薇育种的研究历程和发展趋势，并对引种应用研究现状进行概述。针对紫薇研究现状，展望了未来研究方向，以期在后续研究中加大紫薇调查力度、完善种质资源库、建立信息共享渠道；从花色、香味、株型、抗性及延长花期等方面拓宽育种方向，利用生物及智能技术手段加强育种技术研究，加快紫薇种质创新；因地制宜，不断开发紫薇应用形式，充分发挥紫薇资源价值。 |
| 英文摘要: |
| Lagerstroemia is a native plant in China, which has been cultivated for more than 1 500 years. It is an excellent summer flower woody plant, and is widely used in urban landscaping because of its beautiful color, long flowering period and the advantage of purifying air. The germplasm resources of Lagerstroemia indica are extremely rich. There are about 60 species of Lagerstroemia in the world, 40% of which are in China. The results of national and regional investigations have laid a good foundation for the study of L. indica. In recent years, the cultivation and application of new cultivars have been increased in various regions. The breeding method is mainly traditional breeding, and many new cultivars with good characters and high market value have been cultivated. With the rapid development of breeding technology and molecular biology, a breakthrough has been made in the researches on molecular assisted breeding of L. indica. In this paper, the classification research, germplasm resources, breeding research and introduction and application of L. indica were reviewed. We systematically sorted out the germplasm resources of L. indica in China, including 24 wild species and 350 cultivars, discussed the research process and development trend of breeding of L. indica at home and abroad, and summarized the current situation of introduction and application research. In regard to the current research status of L. indica, this paper offered reflections on future research directions to enhance investigations of L. indica, improve germplasm resource banks, and establish information sharing channels; efforts on breeding should be expanded beyond flower color, fragrance, plant type, resistance and extension of flowering period; and biological and intelligent technologies should be leveraged to strengthen breeding techniques and accelerate innovation in L. indica germplasms. Continuous application forms for L. indica resources should be developed according to local conditions to fully realize their value. |
