摘要
为掌握我国主要粳稻品种食味品质概况,明确符合《中国好粮油稻谷》标准要求品种数量比例,收集了粳稻品种材料333份,对食味品质、蛋白质含量、垩白等指标进行了检测分析。结果表明:食味值符合中国好粮油标准要求的品种数量占比约42%,按推广面积估算比例约为37%;垩白指标符合中国好粮油标准要求的占比为90.5%;粗蛋白含量平均值为8.8%,小于8.0%的样品占比为22.1%。通过本项目研究,基本掌握了我国主要粳稻品种的品质概况,为进一步完善好粮油标准和有效推进中国好粮油行动计划提供数据支撑。
In order to assess taste quality of main japonica rice varieties in China,and illustrate exact proportion of varieties meetingthe requirements of the standard China Good Grain and Oil—Paddy,333 samples of japonica rice varieties were collected and their indexes including taste quality,protein content and chalkiness were detected and analyzed.The results revealed that for tastevalue the proportion of the varieties which met the requirements of the standard China Good Grain and Oil was about 42%,which equals to about 37%calculated by promotion area;for chalkiness the proportion was about 90.5%.The average content of crude protein was 8.8%,in which the proportion of samples with the value lower than 8%was 22.1%.It provides a theoretical support for further optimizing standards and effectively promoting action plans in grain and oil in future by getting exactly the general situation of japonica ricequality in China.
