The possibility of introducing grain maize into Okinawa region as winter crop was investigated at Ishigaki Island in the sub-tropics. Three maize varieties, Wasehomare (very early), Takanewase (early) and Hyugacorn (late), were sown every month from November, 1979 to February, 1980. As a result, the average growing days and heat-unit accumulations were 97 days and 1, 900℃ in Wasehomare, 107 days and 2, 100℃ in Takanewase, and 121 days and 2, 440℃ in Hyugacorn, which showed varietal differences in both characters. However, the most accurate differences related with the earliness were observed in the heat-unit accumulation between germination and silking stage. All plants of every plot produced at least one normal ear, which suggests that grain maize production and setting breeding nursery in winter at this region is likely to be possible.
