摘要: 以玉米为研究对象,运用灰关联分析和因子分析对10份玉米种质的12个农艺性状进行综合评价,探讨这两种统计分析方法在玉米种质综合评价上的应用效果。结果表明,综合评价较好的2个品种分别是Suwan1和下层云优78,两种分析方法的结果基本一致,从而提高了综合评价的可靠性和科学性。

关键词: 玉米, 灰关联分析, 因子分析, 综合评价

Abstract: Ten maize varieties were evaluated comprehensively by using gray relation and factor analysis.The effects of the two statistical methods on comprehensive evaluation were discussed.The evaluation results showed that Suwan 1 and Xiachengyunyou 78 were the better varieties and the results of two statistical methods for maize germplasm were in agreement with reality basically.The application of gray relation analysis and factor analysis could improve the reliability of comprehensive evaluation for maize germplasm.

Key words: maize germplasm, gray relation analysis, factor analysis, comprehensive evaluation
