The differentiation of varieties of peppers in Japan

Abstract

1. Though the dry pepper of Japan is a famous product abroad and the sweet pepper is gradually becoming more popular as a vegetable in this country, the study of variety has not been extensive enough. So we collected many varieties from the whole of Japan in 1949, then tried to clear the synonym and similarity by studying their differentiation considering their production and use.
2. We surveyed the leaf shape and quality, ha-bit of branching and fruiting, calyx shape, fruit season and foliage type. From these results we classified these varieties into the following 6 variety groups and 17 representative varieties as compared to ERWIN's and BAILEY'S systematic studies of peppers.
1. Goshiki group …… Goshiki
2. Enomi group. ……Enomi
3. Takanotsume group. Takanotsume, Hontaka, Daruma
4. Yatsubusa group……Koyatsubusa, Nagaya-tsubusa, Yatsubusa, Ohyatsubusa
5. Fushimi group……Sapporofuto, Nikko, Fushimikara, Fushimiama
6. Large fruit group……Shishi, Large Bell, Pimento, Squash
3. The variety differentiation is common with those in other parts of the world. And in Japan, Takanotsume and Yatsubusa groups develop nottably but Large fruit group is not so much to look at, and there is no Golden group as ERWIN explained.
