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。
Since the 1980s till now, the development of high-quality rice has undergone three development stages. Now, the production of high-quality and safe rice has entered a golden period of steady development. In the 1990s, new varieties of rice with good taste cultivated in Heilongjiang Province were mainly long-grain ones. The price of long-grain rice also went up continuously. The farmers’ demand for long-grain varieties also intensified. According to market changes and needs, Heilongjiang Provincial Academy of Land Reclamation Rice cultivated the second long grain cultivars Kenillai 12, from 2003 to 2013 accumulated 29.2366 million mu in Heilongjiang Province, now the annual area of about 500 Mu, 11 years farmer because of Ken 12 directly and indirectly total income up to 76.58 billion yuan, now the second plot area has the largest planting area, there is no alternative varieties. In this paper, the background of Kening 12 breeding and economic benefits were statistically analyzed to provide reference for the breeding of fine varieties.
