Application of Radar Chart Analytical Method in Tobacco Variety Trial

We employed radar chart method for the comprehensive evaluation of seven tobacco varieties on the number of leaves, the weight of single leaf, the output per ha, average price, superior tobacco ratio, the content of nicotine, reducing sugar and potassium content based on comprehensive consideration of many indices and coordination in experimental sites of Zhucheng in 2007. The results showed that CF212 and CF202 performed best. 9803, LJ935, Y8303 and Y017 were in order from good to bad. NC89 performed the worst. The evaluation results were in accordance with actual performance. So the application of radar chart analytical method in tobacco varieties trial is feasible.
