5、 China)Abstract ： In order to understand the characteristics of flue - cured tobacco varieties introduced from Zimbabwe ,a comparative experiment on two varitiesj. e KRK23 and KRK26 was carried out in low and mid altitude regions ( from 1 120 m to 1 660 m) in Yunnan with K326 as the control. The res
6、ults showed that the height of topping plant of the two varieties from Zimbabwe were higher than that of K326, the stalk circumference, the internode length, leaf width of the biggest leaf were th<! same and the curable leaf number of the two varieties from Zimbabwe were larger than those of K326
7、 The field occurrence of Black shank, Granuville wilt and Tobacco mosaic virus in the two varieties were higher than in K326, and the incidences of four kinds of leave spot diseases in the two varieties were smaller than in K326 Viewd from the economic traits high-yield and stability, KRK26 performed better than K326 and KRK23.
