Abstract: In order to provide a reference for the selection and breeding, Seven index of main characters of 11 Flue-cured Tobacco lines were analyzed and evaluated by the way of the grey relational grade. The results indicated that comprehensive performance of the lines 2002005-8 and 2002004-11 were the best, eight lines of all lines were better than K326. The results of equal weight correlation degree and weighted correlation degree were the identical and coincided with actual performance of the lines. 8 lines had more considerably preponderance and could be tested further.
