本文概述了该项目研究的意义、研究方法、技术路线、研究进展与所取得的成果 ,以及项目研究的创新点和理论意义。研究结果表明 :从种质资源的地理分布、品种类型、表型分化、生态环境、遗传背景等都充分显示了西藏油菜种质资源具有十分丰富的生物多样性。在此基础上 ,提出了油菜的自然分类系统 ,进一步丰富和完善了以往的分类系统 ;提出了油菜演化的二阶段假说和可能存在的演化模式 ,进一步完善了油菜演化系统 ;提出了西藏是白菜类型和芥菜类型油菜起源地之一的观点。
This article summarizes the significance of the project, research methods, technical routes, research progress and achievements made, as well as the innovative points and theoretical significance of project research. The results showed that: from the geographical distribution of germplasm resources, species types, phenotypic differentiation, ecological environment, genetic background, etc. have fully demonstrated that Tibet rapeseed germplasm resources are very rich in biodiversity. On this basis, the natural classification system of rapeseed is proposed, which further enriches and improves the previous classification system. The second-stage hypothesis of rapeseed evolution and possible evolutionary modes are proposed to further improve the rapeseed evolutionary system. Type and mustard type rape origin point of view.
