| 摘 要： | 利用粳稻02428突变体的RIL群体336个F9家系,对糙米中总黄酮和生物碱等2种功能活性成分含量的变异及其与主要农艺性状的相关性进行分析.结果表明,①2种功能活性成分在F9家系间均有较大的变异,其中生物碱含量变异最大,总黄酮变异最小,变异系数分别为55.87％和22.67％.②剑叶宽与总黄酮含量(0.135**)、结实率与生物碱含量(0.130**)呈极显著相关；穗下节长与总黄酮含量(0.127*)、秕粒数与生物碱含量(-0.125*)呈显著相关.③剑叶宽、穗下节长与总黄酮含量、秕粒数与生物碱含量的相关关系主要是直接效应,直接通径系数分别为0.129,0.250和-0.298;结实率与生物碱含量的相关主要是通过株高、剑叶长宽、穗颈长、穗下节长、1～2节长、穗长、实粒数、秕粒数的间接作用,说明剑叶宽、穗下节长、秕粒数和结实率可作为高含量总黄酮、生物碱水稻品种选育的重要参考指标. |

| Abstract: | The correlation between functional activity substants contents and main agronomic characters was analyzed using 336 RIL population(F9) derived from an Mutant 02428 of a set brown rice.The results showed that: (i) There were high variation among total flavones and alkaloid in brown rice for RIL.The variation coefficient of alkaloid content was the highest(55.87 %),whereas that of flavones content was the lowest(22.67 %).(ii)There were very significant correlation between flag leaf width and total flavones co... |
