    河南浓香型烟区烤烟品种(系)适应性研究

    Study on the Adaptation of New Flue-cured Tobacco Variety (lines) with Strong Aroma Style in Henan

    • 摘要: 为了筛选适应河南省特定生态条件下的优良烤烟新品种,以2010年区域试验为基础,采用AMMI模型对4个试点7个品种(系)的主要经济性状和感官质量进行了稳定性和适应性分析。结果表明,7个品种(系)产量在适宜范围内,均价和上等烟比率因环境不同而存在变异,品系Y102产量、产值、均价和上等烟比率最高,具有特殊适应性;Y106产量高、质优且适应性广;H8190产量较高,均价和上等烟比率低于对照,稳定性较好;优选一号综合表现优于对照;8182和8122经济性状表现较差。烤烟品种(系)的感官质量存在显著的基因型与环境互作效应,Y102和Y106评吸得分高且适应性广。

       

      Abstract: In order to select elite flue-cured tobacco varieties which adapted to specific ecological conditions in Henan, the stability and adaptation were analyzed with AMMI model. The data of 7 varieties (lines) were obtained from 4 experimental areas of flue-cured tobacco regional trial in Henan province. The results showed that the yield of 7 cultivars were in suitable range. The average price and the rate of grade A cured leaves showed significant variation at different locations. Line Y102 had the highest yield, value, average price and the rate of grade A cured leaves, with good adaptation to specific environment; Y106 had better economic characters and adaptability. The average price and the rate of grade A cured leaves of H8190 were lower than the control NC89, while the yield and stability was better; the economic traits of Youxuan1 was better than control, while 8182 and 8122 were lower than control. There was significant G×E interaction for total score of smoking quality among different varieties (lines). Y102 and Y106 had better smoking quality under different locations.
