| Abstract: | New hybridized combinations in Henan maize regional trail were comprehensively evaluated on yield and its related agronomy characters,based on grey relational degree analysis and analysis of variance,respectively. Results showed that the two evaluation results were different and more characters were considered in grey relational degree analysis.what more,the standard was more strict in grey relational degree analysis than in analysis of variance. |
