摘要
文章应用主成分分析方法,对18个油葵杂交种的12个性状进行分析,分析的结果与品种的实际表现基本一致。结果证明,由于各遗传性状对品种的重要性不同,运用主成分分析法对向日葵杂交种进行多性状综合评判,比单纯依靠产量结果对参试品种进行评判更具有科学性。这种方法可作为品种比较试验中对参试种进行综合评判的一种有效方法。
Principal component analysis was conducted to test 12 inheritable characters in 18 oilseed sunflower crossed varieties, The result showed that principal component analysis was an effective and scientific way to compare the systhetical inheritable characters of candidate varieties in variety-comparing test since the method used to analyze multiple characters was more scientific than single yield character analysis.
