摘　　要：对111份云南改良稻种和77份元阳地方稻种采用程氏指数法进行籼粳分类,比色法测定抗性淀粉、γ-氨基丁酸和总黄酮含量,并用SPSS软件对数据进行统计分析,结果表明:(1)总体抗性淀粉含量籼型>偏籼>偏粳>粳型,γ-氨基丁酸含量则相反,黄酮含量与籼粳分化的关系不明显;(2)抗性淀粉、总黄酮含量有色米>无色米,γ-氨基丁酸含量无色米>有色米。总体功能性成分含量有色米>无色米,籼稻>粳稻,糙米>精米,地方种>改良种,有色、籼型糙米功能性成分最高,揭示了籼粳分化和米色与抗性淀粉、γ-氨基丁酸与总黄酮含量的关系。A study on functional compositions of rice included 111 improved varieties of Yunnan province and 77 Yuanyang local varieties. Cheng＇s index rras used to distinguish indica-japonica rice, spectrophotometry determination content of functional compositions （including resistant starch of polished rice; γ-aminobutyric acid and flavones of unpolished rice）, at last SPSS software analysis the data. The main results were as follows： （ 1 ）All samples＇ content of RS was Indica 〉 Indica-like 〉 Japonica-like 〉 Japonica, but content of GABA was opposite, the relationship between Flavones and Indica-Japonica type was inconspicuous ; （2） Content of RS and Flavones was colored 〉 colorless,but content of GABA was colorless 〉 colored. In a word,as to the functional content,colored 〉 colorless, Indica 〉 Japonica, unpolished 〉 polished, local 〉 improved. The colored, Indica, unpolished, improved type was best. It recovered the relationship between Indica-Japonica type, colored-colorless,local or improved, polished or unpolished ice and functional compositions.
