Abstract

The invention belongs to the technical field of plant diseases, in particular to a method for identifying potato scab resistance. The invention provides a method for identifying potato scab disease resistance, which comprises the following steps: performing rooting culture and inducing culture of mini-potatoes on potato virus-free seedlings, inoculating fermentation broth of scab pathogenic bacteria during the induction culture, and continuing the induction culture The production of mini-potatoes, the incidence of plants and mini-potatoes were observed during the process, and the resistance to potato scab was judged according to the area of ​​micro-potatoes and the necrosis grade of the plants. According to the mechanism that scab pathogenic bacteria use pathogenic toxins to infect potato tubers to cause disease, the invention combines the techniques of tissue culture of potato virus-free seedlings and liquid-induced mini-potatoes to identify the resistance of potato scab disease. The identification period of the identification method provided by the invention is controlled at about 40 days, which greatly shortens the identification period.

Description

technical field

[0001] The invention belongs to the technical field of plant diseases, in particular to a method for identifying potato scab resistance. Background technique

[0002] Potato scab (Potato scab) is an important disease caused by soil Streptomyces. Among them, Streptomyces.Scabies, Streptomyces.acidiscabies, which cause acid scab, and Streptomyces.turgidiscabies, which cause convex scab lesions, are the three most common potato scab species, and the research is relatively concentrated. The epidermis of potato tuber infected with scab will produce brown spots, which will gradually expand, the tissue around the infection point will gradually necrosis, the surface of the tuber will become rough, and the tissue will become cork, which will seriously affect the quality of potatoes. According to statistics, the occurrence of potato scab is more serious in areas with alkaline soil, continuous cropping for many years, and vermiculite-based greenhouse mini-potato produc...
