为了选育可以在辽宁省种植的食味品质类似‘越光’的粳稻品种，辽宁省水稻研究所从日本引进优质米品种‘越光’，与高抗逆品种‘津原9540’和优质粳稻品种‘辽粳294’为亲本杂交配组，选育获得优质食味粳稻品种‘辽433’。‘辽433’的糙米率、精米率和整精米率类似‘越光’，食味值高于‘越光’，达到83，并且稻瘟病抗性和抗倒伏能力显著提高。‘辽433’的二次枝梗数较少，在生产实践中要注意插植密度。‘辽433’的成功选育说明利用‘越光’为亲本材料，可以选育优质食味的北方粳稻新品种，促进了北方粳稻的食味定向育种及改良工作的开展。

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.
