Naoki Hata, Yūki Toyonaga, Tatsuya Uemachi

Abstract
There is renewed interest in cultivating and using various traditional vegetables in Japan. In Shiga Prefecture, it is being desired to promote vegetable production through developing production area of some native vegetable varieties certified as Ōmi-no-Dentō-yasai, but the available scholarly information regarding these varieties is limited and has not been thoroughly compiled. In this review, we present the available information for the Ōmi-no-Dentō-yasai and describe the background and research trends of specific varieties, while also clarifying their relationships with other native vegetables in Japan. The compiled information may be useful for increasing the production and improving the marketing of each variety certified as Ōmi-no-Dentō-yasai as well as for future studies on these native vegetables in Japan as well as in Shiga Prefecture. In addition, the differences among the Ōmi-no-Dentō-yasai reflect the varietal differentiation and diversity of the traditional vegetable species cultivated in Japan.
