A comparative study for growth characteristics of four cultivars was performed at Tanegashima Island in the southern Kyushu region, Japan: Tanegashima native species "Tanegashimazairai" and "Kitanohato" and Okayama native species "Okayamazairai" and "Hatoroman". "Okayamazairai" and "Hatoroman" demonstrated smaller fruit size during drought-like conditions. Because of the warm climate of Tanegashima, "Kitanohato" did not demonstrate stable and high yields owing to early flowering and fruiting before attaining full plant growth. In contrast, several ripe fruits of "Tanegashimazairai" could be harvested during hot and dry weather, indicating that cultivation of "Tanegashimazairai" was possible in the southern region of Kyushu. In consideration with the typhoon season, the fast-growing native species "Tanegashimazairai" can be seeded in March and harvested early, before the typhoon season. Best yields were achieved with a ridge width of 60 cm. We propose that "Tanegashimazairai" should be used to develop a new cultivar with excellent drought and heat tolerance, lodging resistance, and yield potential.
