Abstract:

In order to identify resistance to phytophthora blight of hot pepper quickly and accurately, the phytophthora blight resistance of 36 hot pepper materials was identified by two molecular markers closely linked with resistance genes and field surveys. Identification results by molecular markers completely consistent with the results of field surveys on 26 materials, including 22 resistant materials and 4 susceptible materials. 3 materials had the opposite identification results by two ways. 4 materials had the different results in two markers. These differences may be caused by the diversity of resistance loci and diverse expression of resistance genes.
