Abstract

The invention discloses a CAPS marker closely linked with a cowpea rust resistance gene and an application thereof. The CAPS marker comprises the sequence shown in SEQ ID No.1. The present invention uses the marker closely linked with the rust resistance gene, and can judge whether it contains the target rust resistance gene according to the genotype of the detected material, and then infer its rust resistance phenotype. Compared with the traditional rust inoculation identification, the identification process is free from environmental interference, and the obtained results are more accurate.

Description

technical field

[0001] The invention relates to a molecular marker, in particular to a CAPS marker closely linked with cowpea rust resistance gene and application thereof. Background technique

[0002] Cowpea, also known as beans, long cowpea, and daisy beans, is an important legume vegetable crop in my country. Cowpea has high nutritional value, rich in protein and a small amount of carotene, vitamin B and vitamin C. Cowpea mainly eats its tender pods, which can be stir-fried, cold-dressed, decocted, pickled and sour, and are deeply loved by the people. Cowpea is one of the popular vegetables widely cultivated in my country. It has strong adaptability and is planted all over the country except in alpine regions. The annual sown area of ​​cowpea in my country exceeds 5 million mu, and the total output exceeds 8.25 million tons. my country is one of the main producers and consumers of long cowpea, and the annual cultivation area accounts for about 1 / 5 of the world.
