The present study was conducted to clarify the relationship between fruit Brix and other chemical components related to taste in chili peppers and to clarify how Brix, which changes in response to environmental stress, is related to other traits such as yield. The experiments were conducted from 2015 to 2019. In experiment 1, 39 varieties of Capsicum annuum were cultivated in 2015 and their pungency and the taste components were evaluated. Relationship of pungency and taste components among varieties were also investigated. In experiment 2, Japanese chili pepper cultivars ‘Manganji’, ‘Fushimiamanaga’ and ‘Botankosho’ were grown under several stress conditions from 2015 to 2019 to determine the relationships of pungency and the taste components in each individual variety. In experiment 3, we observed the effect of stress conditions on plant growth performance and yield using drought stress and salinity stress on ‘Shishito’, ‘Sapporo’ and ‘Botankosho’ cultivars. In experiment 1, although significant positive correlation was found between total sugar content and glucose content in all groups, there was no significant positive correlation between Brix and total sugar content. In experiment 2, a significant positive correlation was found between total sugar content and Brix in all cultivars under all stress conditions. Moreover, a significant positive correlation was found between total sugar content and Brix in each variety. These results clarified that it was not appropriate to use Brix for the comparison of varietal difference of total sugar content but that it was possible to estimate the differences among treatments and individuals within the same variety. In experiment 3, we also found that stress during cultivation increased Brix and capsaicinoid content, and decreased yield, fruit size, and number of leaves. The stress induced increase in Brix because of reduced yield and fruit size, and the effect of reduced photosynthetic ability on Brix due to reduced number of leaves seemed rather small.
