In order to breed highly palatable cultivars suitable for direct sowing in rice, we tried to incorporate the genes for low-temperature-germinability into highly palatable Japanese cultivars and selected excellent backcrossed lines with low-temperature-germinability. We found that several foreign cultivars were useful, so we developed backcrossed BC2F2 (Koshihikari*3/M202, Hinohikari*3/M202, Koshihikari*3/Italica Livorno, Koshihikari*3/Mutashali and Kinuhikari*3/Mutashali) or BC3F2 (Hinohikari*4/M202) populations and selected them for low-temperature-germinability.
