摘　　要：为了提高南繁育种的选择优势,分别将6种寒地粳稻品种种植于黑龙江省齐齐哈尔市和海南省三亚市,对其生育性状进行比较分析。结果表明:寒地粳稻品种于海南种植表现生育期明显缩短。因此,水稻育种过程中,生育期的确定应在黑龙江省进行严格选择。株高和叶片数减少,分蘖力降低,穗长、穗粒数各品种表现不一,千粒重下降,而穗形、粒形、芒型变异小。In order to improve the selective advantage of the south breeding, six varieties of cold region japonica planted in Sanya of Hainan province and Qiqihar of Heilongjiang province, its growing characters were compared. The results showed that the growth periods of japonica planted in Sanya shortened obviously, Therefore,the critical periods should be determined in Heilongjiang province. Plant height and leaves dropped, tiller ability declined,spike length and grain number per spike changed as different japonica planted in Hainan,the 1 000-grain weight dropped,but spike,grain and beard shape hardly changed.
