영문 초록

Paprika (Capsicum annuum) cannot grow or set fruit in temperatures that are higher than the optimal level. This study assesses thecharacteristics of 52 paprika accessions introduced from the agrobiodiversity center and the world vegetable center during a high temperatureperiod in order to develop heat tolerant lines. As a result of controlling the temperature in two greenhouses by side ventilation and foggingsystem, the average daily temperature of the high temperature regime was 34.3℃, which was 2.4℃ higher than that of the normal temperatureregime. Plant height, stem diameter, fruit set, fruit weight, fruit shape, pericarp thickness, soluble sugar content, yield, and marketable fruitdevelopment rate were all investigated as vegetative and reproductive growth-related parameters. Plant height, fruit weight, pericarp thickness,and yield were all reduced during high temperature treatment. Six germplasm lines (T12, T15, T26, T29, T32, and T36) were selected ashigh-temperature tolerant lines based on these parameters. The selected lines will be used to breed heat-tolerant cultivars as well as crossbreedingfor genetic analysis.
