13份烤烟新品系品质综合评价OA

To identify high-quality flue-cured tobacco varieties suitable for cultivation in Guiyang County,Hunan Province,this study systematically assessed the appearance quality,physical properties,conventional chemical components,and sensory evaluation attributes of 13 new flue-cured tobacco lines(V1 to V13),with'MSK326','MS Xiangyan 7',and'MS Yunyuan 87'as controls.The comprehensive evaluation index(CEI)was employed for comprehensive evaluation.The results indicated variations in different quality indicators among lines.V8('MS Xiangyan 7'×'QX-3')and V11(YJ21077:'Xiangyan 7'×'G80')had higher CEI values(61.45 and 67.10,respectively),surpassing the controls.Regarding upper leaves,V8 had best appearance quality and suitable leaf thickness,and V11 had ideal leaf length,leaf width,and single leaf weight.V8 and V11 had high chemical component usability index(CCUI)values(74.40 and 72.96,respectively)and total sensory evaluation scores(both 53.4).The two lines were thus suitable for large-scale trial cultivation in Guiyang County,Hunan Province.V2 and V9 performed well in sensory evaluation but remained to be improved in appearance quality and conventional chemical components.They had certain potential for promotion and were suitable for small-scale trial cultivation.
