摘　　要：从20世纪80年代至今,水稻优质米发展起起落落经历了三个发展历程,现在优质安全稻米生产进入稳定发展的黄金时期。在20世纪90年代,黑龙江省新培育出的口感好的水稻品种多以长粒形为主,长粒形稻谷价格也不断提升,农民对长粒形品种的需求也愈演愈烈。根据市场的变化与需求,黑龙江省农垦科学院水稻研究所育成了第二积温带第一个长粒形品种垦稻12,2003～2013年在黑龙江省累计种植2923.96万亩,现在年推广面积约500万亩,11年农民因垦稻12直接和间接增收累计总额可达765.8亿元,现第二积温区种植面积最大,至今没有可替代品种。本文对垦稻12选育背景及所创造的经济效益进行了统计分析,旨为优良品种的选育提供参考。The golden time of the rice production which was quality and safety came with three development processes from the 1980s to now. In the 1990s, taste good rice with long grain shape-based were bred in Heilongjiang Province, increasingly high prices encouraged farmers to demand for more long-grain varieties.According to changes in the market demand, the first long-grain shaped KenDao 12 in second active accumulated temperature zone was bred by Institute of Rice of Heilongjiang Land Reclamation Academy of Sciences, R had accumulatively distributed in 29.2396 million mu during 2003-2013 in Heilongjiang Province and keep about 5 million mu extension area every year, cumulative total income including indirectly an directly of farmers reach 76.58 billion yuan in 2011,there has been no alternative varieties in second active accumulated temperature zone. Provide a reference for selection of the ideal cultivar is the aim of this article which by analyzing statistically the breeding background and the social benefits of Kendao 12.
