| 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. |
