摘　　要：采用灰色模糊多维综合评估方法 ,对新引进的 1 0个烤烟品种的 1 3个性状进行综合评估 ,结果表明 :RGH5 1综合性状优良 ,好于K32 6 ,主要表现在产量、产值、均价高和上等烟较多 ,赤星病发病较轻 ,值得推广 ;PVH0 8综合性状较好 ,优于K32 6 ,主要表现在产量、产值和均价较高 ,烟碱含量相对较低 ,K2 O含量较高 ,南方根结线虫病发病轻 ,建议进入下一轮生产试验 ;PVH 0 1、PVH 0 2、PVH0 3、PVH0 5、PVH0 6和RGH1 2综合性状一般 ,与K32 6相当 ,建议分生态区明确品种特性 ;PVH 0 9和RGH0 4为综合性状较差的品种 ,较K32 6差 。flue-cured tobacco varieties introduced newly were evaluated comprehensively by fuzzy analysis on 13 traits. The results indicated that the comprehensive characters of variety RGH51 were more excellent than K326, expressing on it's high yield, output value, average price and the rate of high-grade tobacco, and lower occurence rate of brown spot disease. The varietiy PVH08 was a good one but less than RGH51. It was testified to be better in yield, output value, average price, the rate of high-grade (tobacco), and the contents of K_2O and nicotine, and lower occurence rate of the root knot nematode disease. It should be taken part in the next production-text. The varieties PVH01, PVH02, PVH03, PVH05, PVH06 and RGH12 were of common varieties on their comprehensive characters and were suggested to study their traits under different environments. The varieties PVH09 and RGH04 needed to conducting further test.
