Abstract: Comparative analysis of 89 rice varieties which were bred during the 12th five-year plan period in Heilongjiang Province in this paper. The results indicated that the total number, yield, quality, disease resistance and stress resistance of the varieties bred during the period of the 12th five-year plan were improved compared with the varieties bred during the period of the 11th five-year plan. The genetic basis of breeding was still very narrow. In the future, new high quality rice germplasm resources should be introduced from both domestic and exotic, and new backbone parents should be excavated.

Key words: the 12th five-year plan, rice varieties, backbone parent

摘要： 对黑龙江省“十二五”期间育成的89个水稻品种基本情况进行了对比分析。结果表明，黑龙江省“十二五”期间育成的水稻品种在育成品种总数、产量、品质及抗病、抗逆性等方面均有一定提升；黑龙江省水稻选育的遗传基础仍然十分狭窄，配制组合时不可避免的出现重复，审定品种间亲缘关系较近。今后在黑龙江省的水稻育种工作中应从国内外引进新的优质种质资源，努力挖掘新的骨干亲本。
