Abstract: In order to breed the japonica rice variety with similar taste to Koshihikali which could be planted in Liaoning Province, Koshihikali was introduced from Japan and‘Liao 433’was bred by Liaoning Rice Research Institute. It was a progeny of the cross between the F1 of Koshihikari and‘Jinyuan 9540’with high resistance and‘Liaojing 294’with good rice quality. The brown rice rate, milled rice rate and head rice rate of ‘Liao 433’were almost the same as that of Koshihikari, while the taste value was higher than that of Koshihikari, and the resistance to rice blast and lodging was significantly improved as well. The suitable planting density of‘Liao 433’should be paid attention to ensure the production in practice because of less secondary branch numbers. Koshihikari could be introduced to promote the directive breeding and improvement of good taste japonica rice variety in north China.
