关于我国籼稻谷粒型分类的探讨

Discussion about the grain shape of indica rice in our country

以南方六省籼稻谷样品为研究对象,探讨我国籼稻谷粒型的分类指标值及判定方法,从现 有数据分析建议以粒长作为分类依据,粒长≥6. 0 mm 为长粒,粒长5 . 6-5.9 mm 为中粒,粒长 〈5.6 mm 为短粒.

Taking southern six provinces indica rice as samples,the classification indexes of indica rice kernel shape and determinant is discussed. According to the existing data,the kernel length is recommended as the basis of classification. The result is that the kernel length≥6. 0 mm is called as long kernel grain,5. 6 mm ~ 5. 9 mm as medium kernel and less than 5. 6 mm as short kernel.
