不同烤烟品种在咸阳旬邑烟区的适宜性评价

Suitability Evaluation of Different Flue-cured Tobacco Varieties in Xunyi Tobacco Region of Xianyang

为筛选出适宜旬邑烟区生态环境的烤烟新品种,为其优质烟叶生产和利用提供依据,于2022年以旬邑烟区主栽品种秦烟99为对照,采用大田试验方法,研究秦烟99、秦烟96、秦烟201、中烟100、豫烟13和Y2001这6个品种的大田生育期、植物学性状、农艺性状、田间自然发病率、经济性状、常规化学成分含量、烤后烟外观质量和感官质量的差异。结果表明,不同烤烟品种的生育期差异较小,为142~155 d;秦烟96和Y2001田间生长势强,抗病性强,产量、产值和中上等烟比例较高,外观质量和感官质量表现优异,化学成分协调性好,可作为旬邑烟区储备品种进行推广种植。

In order to screen new varieties of flue-cured tobacco suitable for the ecological environment of Xunyi tobacco area,and to provide a basis for the production and utilization of high-quality tobacco leaves,we used Qinyan 99 as the control in 2022,which was the main cultivar in Xunyi tobacco growing area.The differences in field growth period,botanical properties,agronomic properties,field natural incidence rate,economic properties,conventional chemical composition content,appearance quality and sensory quality of flue-cured tobacco were compared among Qinyan 99,Qinyan 96,Qinyan 201,Zhongyan 100,Yuyan 13 and Y2001.Results showed that there was little difference in the growth period among different tobacco varieties,ranging from 142 to 155 days;Qinyan 96 and Y2001 had strong growth potential in the field,strong disease resistance,high yield,output value and the proportion of medium to high grade tobacco.They had excellent appearance and sensory quality,and good coordination of chemical components,which could be used as reserve varieties for promotion and planting in Xunyi tobacco area.
