[0038] (1) Preparation of materials for celery varieties

[0039] Choose specially selected celery, Kunming parsley, American Baileys, Wangsheng, Holland You, Da Vinci, Almighty, Dutch Emperor, Tendera, American Treasure, Orleans, Kasa, Dutch Jade Emperor, Seattle, Rising Sun, Ferrari, Qianfang , Juventus, UTah-52-70R, San Diego, Washington, California Emperor, Tango, Tall Utah 2-70R PS, American Celery, Shaoxing Celery, Napoleon, Jiali, Queen, Summit, Nero, Sabrosa, Thirty-six commercially available celery varieties, such as Lvguiren, Guifei, Sijixicelery, and Saixue, were used as test materials for the identification of celery leaf spot resistance. After 3 years of continuous observation, identification and comparison of preliminary tests, it was known that Sabrosa was resistant to celery leaf spot disease. Highly susceptible, its disease index reaches 98.89, and it is used as the comparison variety of the present invention's test.

[0040] All the above-mentioned celery va...

Abstract

The invention discloses a method for identifying resistance to celery leaf spot disease. The invention screens out Sabrosa, a high-susceptibility variety of celery for the first time, and obtains that taking this variety as a comparison variety, the difference in disease resistance between different celery varieties is the most obvious. The results are accurate and comparable; and it is found that the disease investigation using the third leaf on the periphery of the celery plant as a sample can not only show the strength of the variety's disease resistance, but also reduce the workload in the field and improve the efficiency of identification work; and its The degree of disease represents the disease level of the variety, which has good stability and strong comparability. In addition, the method of the present invention is suitable for simultaneously identifying and screening large quantities of celery variety materials for resistance to leaf spot disease, thereby saving labor.

Description

technical field [0001] The invention belongs to the technical field of plant disease resistance identification, and in particular relates to a method for identifying resistance to celery leaf spot disease. Background technique [0002] Celery (Apium graveolens L.) is a biennial vegetable belonging to the family Apiaceae. It is rich in nutrition and has various pharmacological functions. [0003] Celery leaf spot, also known as early blight of celery, is a fungal disease of celery caused by the half-knowledge fungus Cercospora apii Fres. Great impact. The disease was first discovered by German Fresenius in 1863, and then spread in the United States (Galloway, 1886), and soon became the most serious celery disease in Florida, Ohio and other places (Wilson & Newhall, 1930, Wolf et al., 1955), causing Yield losses of up to 50% or more (Lacy et al., 1996). In my country, leaf spot disease has always been a common disease in celery production in many areas. With the expansion o...
