Abstract
Using the methods of cluster analysis methods, 15 factor of introducing 27 new onions varieties were selected, such as leaf shape, leaf color, growth period, yield etc, according to its bulb color, yield, quality comprehensive divided into five categories. On this basis, the method of principal components analysis is adopted to analyze factor variables for 15 observations, the results shows that cumulative total variance contribution rate amounted to 76.849% of previous 4 common factors, which reflected the most of the characteristic information; according to the scores of all varieties in all common factor, assessing the characteristic of 27 varieties, which sorted by comprehensive score and the result of cluster analysis, this results is used to determine to popularize and apply varieties.关键词
