摘要
对50个陆地棉花品种2009,2010,2011年的产量性状、病害性状与纤维品质性状指标进行单因素方差分析。结果表明,除皮棉产量3 a间差异不显著外,其他性状3 a间或2 a间差异均显著。主成分分析表明,前7个主成分的方差累积贡献率达到80.66%,基本上可以代表所有性状的变异信息。
The yield,disease and quality characteristics of 50 cotton varieties in 2009,2010 and 2011 were analysed by single factor variance analysis.The results showed that lint yield had no significant difference,but other characteristics had significant difference between three or two years.Principal components analysis showed that the first seven principal components variance accumulation contribution rate amounted to 80.66％,which reflected most of the variance information as listed above.
