本文以12份茄子育种材料,探讨了5种鉴定茄子褐纹病抗性的方法。结果表明,几种方法各有特点。方法Ⅰ、Ⅱ简捷方便,可用于褐纹病抗源的大规模筛选,但是不适于抗褐纹病程度不同的感病材料之间的比较。方法Ⅲ、Ⅳ、Ⅴ克服了上述缺点。其中伤口接种法(Ⅲ、Ⅳ)破坏了果皮机械组织,可以在一定程度上鉴别出机械组织引起的抗性。12份茄子育种材料鉴定结果表明:茄子抗源品系及含有抗源的杂交一代均表现明显的抗性。无伤接种情况下,抗源83—02及其杂交一代发病率为0。而在伤口接种情况下,抗源83—02及83—02×苏州牛角(F_1)极个别果实发病,而83—02×紫水(F_1)和83—02×83—04(F_1)发病率仍然为0。说明抗褐纹病材料的果皮有一定的抗病作用,但不是主要作用。
In this paper, 12 kinds of eggplant breeding materials were explored five kinds of methods to identify eggplant brown spot resistance. The results show that several methods have their own characteristics. Methods Ⅰ and Ⅱ were simple and convenient, and could be used for large-scale screening of brown spot disease-resistant sources. However, they were not suitable for the comparison of susceptible materials with different degrees of brown streak resistance. Methods III, IV, V overcome the above shortcomings. The wound inoculation method (Ⅲ, Ⅳ) destroyed the mechanical tissue of the peel, to a certain extent, the mechanical tissue-induced resistance can be identified. The identification results of 12 eggplant breeding materials showed that the eggplant resistant lines and the hybrid generation containing the resistance source all showed obvious resistance. In the case of non-invasive vaccination, the incidence of resistant source 83-02 and its cross was 0. However, in the case of wound inoculation, the incidence of very few fruits in the resistant clumps 83-23 and 83-02 × Suzhou F_1 was still high, but the incidence of 83-02 × purple water (F_1) and 83-02 × 83-04 (F_1) Is 0 Explain the anti-browning material peel has a certain resistance to disease, but not the main role.
