- Abstract:
- 162 pepper collections were selected as the experimental materials，and identification with artificial inoculation was conducted for their resistance to Phytophthora capsici，in order to provide reference for the resistance breeding of pepper.The results showed that 11 collections were resistant to Phytophthora capsici(R)，23 collections were moderately resistant (MS)，18 collections were moderately susceptible(MS)，and 110 collections were susceptible (S).At the same time，the correlation between the disease resistance and 28 morphological traits of these 162 pepper materials was analyzed.The results indicated that there was a very significant correlation between the Phytophthora capsici resistance and the fruit shape，fruit shoulder shape，fruit-based storage calyx and fruit number per plant，and a significant correlation between the Phytophthora capsici resistance and the stem color，leaf color，plant height，plant width and style length.Among the accessions with stronger resistant to Phytophthora capsici，the long finger and long horn pepper took a large proportion.
