Analysis of similarity-difference connection trend were used to evaluate the 14 maize hybrids according to the data of 6 maize test points, which 13 major characters were involved. The result showed that the connection degree between 5 maize hybrids （LZll, LZ2, LZ4, LZ7 and LZ8） and the ideal variety was 0.757 2 - 0.889 7. The comprehensive traits were excellent, so these maize hybrids should be the maize variety regional trial. The other maize hybrids need to be observed and tested further. The analysis of similarity-difference connection trend could estimate the yield productivity and stability simultaneously. It could determine the advantage and disadvantage of maize hybrid comprehensively and accurately.
