In this paper, analysis of variance (AOV) was carried out on 14 characteristics of 26 maize cross combinations bred by Yunnan A cademy of Agricultural Sciences and 2 maize varieties with large planting area. Correlation between the 10 characteristics with significant value in AOV and the principal components was researched, and thus, the comprehensive evaluation formula of principle components of the tested materials was established. Based on the results of principle component analysis and comprehensive evaluation, 7 materials were screened , which were similar to the results of traditional evaluation. This paper provided the basis for the breeding of hybrid maize materials. [ABSTRACT FROM AUTHOR]
