摘要
通过对7个烤烟品种(系)经济性状与环境互作的联合方差及线性模型分析,结果表明,YNH09经济性状稳定性和适应性最好,YH01次之,对照K326综合表现较强,其他品种(系)表现不理想。由于环境因子的差异,各参试材料品种间和地点间的经济性状均存在显著差异,品种经济性状的稳定性和适应性可能受控于不同的遗传体系。此方法可直接指导烤烟品种的比较试验及鉴定,研究结果可为烤烟品种的合理布局和科学搭配种植提供理论依据。
Results through analysis on interactions between economic traits of 7 fluecured tobacco varieties and the environment by joint variance and linear model show that YNH09 has the best stability and adaptability with its economic traits, the second is YH01, the control variety K326 has better comprehensive performance, and the other varieties or lines have performed poorly. Due to the difference of environment factors, there are significant differences on economic traits between the materials tested from different varieties and sites; the stability and adaptability of economic traits of the varieties might be controlled by different genetic systems. This method can be used directly in comparative test and identification of fluecured tobacco varieties, and the study results can provide the theoretical evidences for reasonable arrangement of fluecured tobacco varieties and better variety structure.
