摘要
73个小麦品种的36个品质和农艺性状可聚类为6组。即蛋白质性状,必需氮基酸、非必需氨基酸、产量因素、形态性状和生育期性状。典型相关分析表明,与蛋白质相关的程度是:产量因素>非必需氨基酸>必需氨基酸>形态性状>生育期性状;与必需氨基酸相关的程度是:非必需氨基酸>形态性状>产量因素>生育期性状。关联作用最重要的性状是:单株籽粒产量,千粒重、脯氨酸、丙氨酸、缬氨酸、蛋白质含量、单粒蛋白质产量、单株蛋白质产量、粒长、粒宽、穗长、抽穗期。在对36个性状进行因子分析中,分离出了8个重要综合性状,反映出87%的信息。
Thirty-six characters of 73 common wheat(Triticum aestivum L.)genotypes were divided into6 groups.The cononical correlation with protein chaaracters appeared in the ordder of yield components>non—essential amino acids>essential amino acids>morphological characters>developmental—pe-riod characters while that with essential anino acids was in in sepuence of non—essential amino acids>morphological characters>yield components>devdlopmental—period characters.Characters that playan important role in association and relationship whatever between two character groups involved grainprotein content,protein yield/grain,grain protein yield/plant,analine,proline,valine,grain yield/plant,1,000—grain weight,grain width,ear length and heading time.Eight complex characters con-taining 87% of the informtaion were extracted from the 36 characters studied on the basis of factoranalysis.
