Abstract: Using 2012 cold resistant flue-cured tobacco varieties regional trial in Nanping City, the average yield and average output value of all varieties in three different test points, After the data environment centered,To the GGE biplot map form described the performance of the varieties tested at each test point, the relationship between environmental points, the areas of the distinguish between discrimination and representative and the tested varieties mean vs. stability, The results show that:(1)CB-1 variety in Yanping the trial point average yield, the average output value of the highest, NF-1 strain in Shaowu, Pucheng test point average highest value; (2)Close positive correlation between test points in Shaowu and Pucheng, both with the Yanping test point showed a negative correlation;(3)Yanping, Pucheng, Shaowu each test point has strong ability to distinguish between the varieties tested, As Cold resistant varieties screening test points, Pucheng and Shaowu has the fairly typical;(4)Five varieties tested the performance of high-yield, high value and stable strain of NF-2, NF-1 performance relative yield and stable strain.
