烤烟新品种(系)重要经济性状丰产性和稳定性评价研究

The Research of Flue-cured Tobacco Varieties'(Strains) Important Economic Characters Fertility and Stability Evaluation

为客观评价烤烟新品种(系)的丰产性、稳定性和品种生态布局,为贵州烤烟新品种(系)的审定和推广提供科学依据。将GGE方法引入烤烟区域试验分析中,同时采用GGE双表图及AMMI模型,对2011年度贵州省烤烟区域试验8个生态区域、13个烤烟新品种(系)的产量和产值进行分析。结果表明,2种分析方法均能客观评价烤烟新品系的丰产性和稳定性,GGE双标图方法能更直观准确地反映各品系的最佳适应区域。新品系YQ-1的产量和产值均表现最好,GY1007、A18和2010A4具有特殊适应性,GY1007和A18在德江地区有推广价值,而2010A4在道真地区具有推广价值。

In order to assess the high yield ,stability and adaptability of flue-cured tobacco varieties objectively , and provide scientific proofs for the cognizance and spread of varieties .In this paper ,GGE biplot was introduced into flue-cured tobacco regional trial analysis .GGE biplot method and AMMI model were used to analyze the yields and production values from the regional trials for flue-cured tobacco in 2011 .Thirteen lines of flue-cured tobacco were tested in eight sites .The results showed that both the methods could objectively evaluate the high yield and stabili -ty,but GGE biplot reflected the most suitable regions of variaties more accurately .YQ-1 had the highest yield and the best production value .GY1007 ,A18 and 2010 A4 had special suitability .GY1007 and A18 had expansion value in Dejiang,while 2010A4 had expansion value in Daozhen .
