GGE双标图对抗寒烤烟品种区域试验的分析

利用2012年南平市抗寒烤烟品种区域试验中各品种在3个不同试验点上的平均产量和平均产值，经过环境中心化后的数据，以GGE双标图的图谱形式阐述了参试品种在各试验点的表现、各试验点环境间关系、各试验点的区分力和代表性及各参试品种平均表现和稳定性。结果表明：（1）‘CB-1’在延平试验点平均产量、平均产值最高，‘NF-1’在邵武、浦城试验点平均产值最高；（2）邵武和浦城试验点之间存在紧密正相关，且与延平试验点均表现为负相关；（3）延平、浦城、邵武各试验点对参试品种均具有较强的区分能力，作为抗寒品种筛选的试验点，浦城和邵武具有较强代表性；（4）5个参试品种中‘NF-2’表现既高产量、高产值又稳定的品系，‘NF-1’表现相对高产和稳定的品系。

Application of GGE Biplot Analysis Cold Resistant Flue-cured Tobacco Variety Regional Test

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.
