基于灰色关联度分析的烤烟品种适应性评价

Adaptability Evaluation of Flue-cured Tobacco Varieties Based on Grey Correlation Analysis

通过田间试验研究了8个烤烟品种的生育期、农艺性状、经济性状、化学成分及感官质量差异,并采用灰色关联度分析对其进行综合性状评价。结果表明,T64的生育期较长,T64、贵烟202和云烟100的株高较高,T64、NC102和NC196的有效叶数较多,云烟100、贵烟202和云烟99的叶片较宽大;云烟99、贵烟202、云烟100的产量、产值较高,化学成分协调性较好;贵烟202和云烟100的感官质量与云烟87相当。灰色关联度分析结果显示,贵烟202、云烟100和云烟99的等权关联度值较高,表明贵烟202、云烟100和云烟99综合性状表现最好,在毕节烟区种植适应性强,有待进一步示范验证。

The differences of growth period,agronomic characters,economic characters,chemical composition and sensory quality of 8 flue-cured tobacco varieties were compared through field experiment in this study.The Grey Correlation Degree Analysis is used to evaluate its comprehensive performance.The results showed that the fertility period of T64 was the longest,the topping plant height of T64,Guiyan 202 and Yunyan 100 was the higher,the number of effective leaves of T64 NC102 and NC196 was the more,The leaf of Yunyan 100,Guiyan 202 and Yunyan 99 was larger.The output and output value of Yunyan 99,Guiyan 202 and Yunyan 100 was higher,and have good coordination of chemical constituents.Guiyan 202 and Yunyan 100 have the same sensory quality as Yunyan 87.The results of grey correlation analysis showed that the equal weight correlation degrees of Guiyan 202,Yunyan 100 and Yunyan 99 were higher.Guiyan 202,Yunyan 100 and Yunyan 99 have strong adaptability to planting in Bijie tobacco-growing area,which needed further demonstration and verification.
