Abstract

The invention discloses an SSR molecular marker (Pm-136) linked with a powdery mildew resistant gene pm1 of cucurbita pepo L., belongs to the technical field of breeding of vegetable molecules for disease resistance, and relates to an SSR molecular marker linked with the powdery mildew resistant gene, and an application of the SSR molecular marker. The genetic linkage distance between the molecular marker Pm-136 and the resistance gene is 1.7cm. Whether a disease resistance character transfer offspring plant carries with the resistance gene Pm1 or not can be rapidly and accurately detected by virtue of the molecular marker Pm-136, thus the disease-resistant breeding efficiency is significantly improved; and the breeding cycle is shortened. The obtained marker Pm-136 has the advantages of being stable, reliable, simple to operate, good in repeatability and the like, and has high utilization value in identification of resistant and susceptible varieties and a disease-resistant transfer single offspring plant.

Description

technical field

[0001] The invention relates to the technical field of vegetable molecular disease-resistant breeding, specifically a kind of Cucurbitapepo L.) Powdery mildew dominant disease resistance gene Pm1 Linked SSR molecular markers and the application of the markers in detecting disease-resistant plants. Background technique

[0002] Zucchini is one of the important vegetables of the pumpkin genus that is widely planted around the world. The cultivated area in my country is increasing year by year. Especially in recent years, protected cultivation has developed rapidly, and it has become the second largest cultivated crop after cucumber. Zucchini production is of great significance to increasing farmers' income, adjusting agricultural structure and enriching the people's vegetable basket.

[0003] Powdery mildew is one of the important diseases that harm the mid-to-late production of zucchini. After the plant is infected with powdery mildew, photosynthesis is se...
