Abstract

The invention discloses an identification method for clubroot disease resistance of high mountain radishes in a field. The identification method comprises the following steps: selecting experimental radish varieties, enriching bacterium sources of a clubroot disease nursery in a high mountain region, and sowing radishes; grading clubroot disease morbidity degree of full-grown radishes to obtain disease condition grades of the radishes; calculating radish variety disease condition indexes according to the disease condition grades of the radishes and a radish variety disease condition index general formula; and evaluating the resistance type of each radish variety to the clubroot disease by combining a radish disease resistance evaluation standard according to a calculation result. According to the identification method, the disease condition grading of the radishes which are infected with a disease is simplified; the influence on radish clubroot disease condition grading caused by black spots and black scars on the radishes is excluded; the existing grading mode is changed essentially; the overall identification process and the result processing analysis become simple, and meanwhile, the clubroot disease resistance of different radish varieties is judged rigorously and accurately.

Description

technical field

[0001] The invention belongs to a method for identifying clubroot resistance of crops, and in particular relates to an identification method for field clubroot resistance of alpine radish. Background technique

[0002] Radish is a 1 to 2-year-old herbaceous dicotyledonous plant of the genus Radish in the family Brassicaceae. It is the second largest vegetable in my country. It has a cultivation history of more than 2,700 years in China, with nearly 2,000 varieties of resources. Its variety resources are very rich in types. There are traditional local varieties suitable for consumption habits in the region and growing in different seasons. The annual planting area of ​​radish in my country has exceeded 18.3 million mu, and it is planted in all provinces, cities, and counties across the country. Radish products are supplied to the whole country every year and exported to Japan, Hong Kong, Taiwan, and Southeast Asia.

[0003] Clubroot is a worldwide soil-borne d...
