巴西橡胶树DUS测试指南研制初探

为加强橡胶树新品种保护工作，在国际新品种保护联盟（UPOV）对DUS测试的基本要求和品种的生物学特性的基础上，制定巴西橡胶树DUS测试指南，阐述了其研制过程，品种测试的特殊性，性状的筛选原则和发展方向等。建议橡胶树DUS测试标准不宜定太高，测试性状要能体现中国育种水平和方向，并遵循UPOV原则。并认为分子标记技术与表型测试技术相结合将逐步成为橡胶树DUS测试的主要手段。

Study on Establishment of DUS Testing Guidelines for Hevea Brasilensis

DUS testing guidelines of Hevea Brasilensis were established which based on basic requirements of International Union for the Protection of New Varieties of Plants (UPOV) and biological characters for enhancing the protection of new variety. The formulation process, testing particularities , rules of character selection and the development direction of DUS testing were introduced in this paper. It was suggested that the criterions of DUS testing should not be so high, and the testing characters should demonstrate Chinese breeding level and direction by following the UPOV principles. It was believed that techniques combined molecular markers and morphology testing will become the primary means of DUS testing on rubber.
