    基于灰色关联分析的津巴布韦烤烟品种综合性状评价

    Comprehensive Assessment of Flue-cured Tobacco Varieties from Zimbabwe Based on Grey Correlation Analysis

    • 摘要: 为筛选出综合性状表现较好的津巴布韦烤烟品种,通过田间试验,收集6个津巴布韦烤烟品种和对照品种云烟87的田间农艺性状、主要化学成分指标、初烤烟叶外观质量和评吸质量指标,采用灰色关联度分析方法,对其进行综合性状评价。结果表明,各参试烤烟品种的评价指标等权关联度排序为KRK26 >云烟87 > T62 > T64 > T63 > T16 > T20,加权关联度排序为KRK26>云烟87 > T62 > T63 > T16 > T64 > T20。KRK26品种的等权关联系数和加权关联系数均排名第一,分别为11.262 4、0.906 7,综合性状优于对照品种云烟87和其他津巴布韦烤烟品种,这一结果与田间实际表现一致。综上,津巴布韦烤烟品种KRK26具有较好的推广潜力,可以在当地进行进一步试验与示范推广。

       

      Abstract: In order to screen for Zimbabwe flue-cured tobacco varieties with better properties, providing decision-making services for the promotion of new tobacco varieties, a field contrast experiment was carried out in tobacco planting base of Hongta group for comprehensive evaluations of agronomic characteristics, main chemical components, appearance quality of flue cured tobacco and the smoking quality of six Zimbabwe flue-cured tobacco varieties and one control variety Yunyan 87, using the method of gray relational grade analysis. The analysis results showed that, all tested flue-cured tobacco varieties were ranked according to equal-weighted correlation degree between comprehensive characters, as follows:KRK26 > Yunyan87 > T62 > T64 > T63 > T16 > T20, All tested flue-cured tobacco varieties were ranked according to weighted correlation degree between comprehensive characters, as follows:KRK26 > Yunyan87 > T62 > T63 > T16 > T64 > T20. The weighted correlation coefficient and weighted correlation coefficient of KRK26 were both ranked first, being 11.2624 and 0.9067 respectively. The comprehensive characters of KRK26 variety were better than yunyan87 and other flue-cured tobacco varieties from Zimbabwe. This result is consistent with field performance of the varieties. In conclusion, these tobacco varieties from Zimbabwe have a good potential for promotion, and should be further popularized.
