【摘要】 以653份云南稻种为材料进行了8种矿质元素含量与4个品质性状及其24个形态性状间的相关性分析,结果表明核心种质的P、K、Ca和Mg含量与绝大多数形态和品质性状的关系密切,以P与茎蘖数(-0.2043** )、K与直链淀粉含量(-0.2043** )、Ca与株高(-0.4151** )、Mg与蛋白质(0.2570** )相关性相对较高; 核心种质的Mn、Zn、Cu和Fe含量与少数形态品质性状的关系密切, 以Fe 与胶稠度( - 0. 1121** )、Zn 与结实率( - 0. 1411** )、Cu 与每穗实粒数(-0 1398** )、Mn与株高(-0.2492** )相关性相对较高。更多还原

【Abstract】 The relationship between 4 quality, 24 morphological traits and 8 element contents of 653 accessions from Yunnan rice were analyzed. P, K, Ca and Mg contents of the core collection were closely related to most of morphological and quality traits, and there existed high correlation coefficients among some traits including P content and stem tillers number (-0.2043 ** ), K and amylose contents (-0.2043 ** ), Ca content and plant height (-0.4151 ** ), Mg and protein contents (0.2570 ** ).Mn, Zn, Cu and Fe contents of the core collection were closely related to a few traits, such as Fe content and gel consistency (-0.1121 ** ), Zn content and seed setting rate (-0.1411 ** ), Cu content and number of grains per panicle (-0.1398 ** ), Mn content and plant height (-0.2492 ** ).更多还原
