中文摘要：

测定了水稻02428与合系35杂交培育的222个R IL（重组自交系）及其亲本的发芽糙米和糙米总黄酮和生物碱含量,对其进行遗传分析及探讨了发芽糙米和糙米中总黄酮、生物碱的含量变化。结果表明,R IL群体发芽糙米和糙米中总黄酮、生物碱呈现广泛的遗传变异,糙米总黄酮含量略高于发芽糙米,但两者均呈正态分布,类似于数量性状的分布特征。R IL群体发芽糙米生物碱含量是糙米的1.5倍,且两者呈偏态分布;为功能水稻的遗传及品种选育提供了一定的理论依据。

英文摘要：

Genetic and difference of total flavonoids and alkaloids content were studied,based on germinated brown rice and brown rice of 222 RILs as well as their parents. The results showed that total flavonoids and alkaloids presented a wide range of genetic variation in germinated brown rice and brown rice of RILs, the total flavonoids content in brown rice was slightly higher than germinated brown rice, but all appeared the normal distribution and similar to the qualitative traits the distribution. Total alkaloids content in germinated brown rice was 1.5 times as much as the brown rice,but all appeared the skewed distribution. This study can be a theoretical basis for genetic and breeding of the functional rice.
