摘要
【目的】探讨不同基因型烤烟主要农艺性状、经济性状指标与主要化学成分指标可用性指数间、烟叶外观和感官质量间的相关关系,为烤烟新品系相关性状指标的选育及推广与应用提供参考。【方法】以HKDN-2、C81-2-2、K326和云烟87为材料,在采用模糊理论分析主要化学成分指标可用性指数(CCUI)基础上,运用灰色关联理论分析主要化学成分指标可用性指数、感官及外观质量评价权重得分与主要农艺性状及经济性状指标间的灰色关联。【结果】(1) B2F和C3F烟叶外观和感官质量权重总分与不同基因型烤烟主要农艺性状指标间的关联度表现为:叶宽>叶长>有效叶数>节距>株高>叶面积>茎围;(2) B2F和C3F烟叶CCUI与不同基因型烤烟主要农艺性状指标间的关联度表现为:叶宽>叶长>有效叶数>节距>株高>叶面积>茎围;(3) B2F外观质量及感官质量权重得分与其单叶重的关联度均高于与C3F的关联度;但B2F的CCUI与其单叶重的关联度则低于与C3F的关联度;(4)主要经济性指标与CCUI、烟叶外观和感官质量权重总分间有一定的关联度关系。【结论】不同基因型烤烟主要农艺性状指标、经济性状指标与烟叶的CCUI、外观和感官质量指标评价权重得分间有着重要的相关关系。
[Purpose]In order to provide a references on selection of the related traits of the new flue-cured tobacco varieties(lines), and its popularization and application, explore the correlation of the main agronomic and economic traits with the main chemical components usability index(CCUI),weight score of sensory and appearance quality evaluation.[ Method]Using HKDN-2, C81-2-2,K326 and Yunyan87 as materials, we analyzed the grey relational grades of CCUI and weight score of sensory and appearance quality evaluation with the main agronomic and economic traits of raw tobacco based on the analysis of CCUI by using the fuzzy theory.[Results]1) The correlation degree of the weight score of sensory and appearance quality evaluation of B2F & C3F with main agronomic traits of the different genotypes flue-cured tobacco was shown as leaf width>leaf length>effective leaf number>pitch>plant height>leaf areas>stem girth. 2) The correlation degree of CCUI of B2F & C3F with main agronomic traits of the different genotypes flue-cured tobacco was shown as leaf width>leaf length>effective leaf number>pitch>plant height>leaf areas>stem girth. 3) The correlation grade between the weight score of sensory and appearance quality evaluation of B2F and single leaf weight was high more than that of C3F, and so did CCUI of B2F was lower than that of C3F.4) There was a certain degree of correlation among the economic traits with CCUI the weight score of sensory and appearance quality evaluation.[Conclusion]It has an important correlation of main agronomic and economic traits of the different genotypes flue-cured tobacco with CCUI, the weight score of sensory and appearance quality evaluation.
