菜薹DUS测试指南制定方法初探

Primary study on test method of distinctness,uniformity and stability in flowering Chinese cabbage

植物新品种的特异性、一致性和稳定性测试是对植物进行新品种保护的基础,菜薹是我国的重要蔬菜作物,但目前UPOV及其他国家并无菜薹的DUS测试指南可供参考。在参考国际新品种保护联盟(UPOV)相关文献和国家植物新品种特异性、一致性和稳定性测试指南总则的基础上,对菜薹DUS测试指南的制定方法进行了初步探讨。测试指南由23个外观形态性状,4个农业生物学性状,1个分组性状和1个抗病性状组成。

The testing of distinctness,uniformity and stability are the base of protection of new variety.Brassica campestris L.ssp.chinensis is an important vegetable crops in China,but there is not any testing guide of its DUS in UPOV and other countries in the world.Based on the reference of UPOV and China,the paper studied the development of DUS in Brassica campestris L.ssp.chinensis.Twenty-three morphlogocal traits,4 agrobiological traits,1 grouping traits and 1 resistance to disease were included in this guideline.
