摘要: 鄂烟101是以鄂白003为母本、KY8959为父本进行杂交,应用系谱法选育而成的白肋烟新品种,2009年3月通过全国烟草品种审定委员会审定。该品种属于中晚熟品种,生长势强,栽植株距较其他品种大,分层落黄成熟。主要经济性状优于对照品种鄂烟1号,原烟外观质量、物理特性与对照品种相当,内在化学成分较适宜、协调,烟碱低于对照品种,吸食品质略优于对照品种。抗黑胫病、TMV,易感赤星病。该品种在产量方面有较大的突破。Abstract: The new burley tobacco variety Eyan101 was obtained by cross-breeding of Ebai003 and KY8959. It was approved by National Tobacco Cultivar Registration Board (NTCRB) in March 2009. The results showed that Eyan101 was one mid-late maturity variety with a strong growth and a wider distance between two adjacent plants than other varieties. Its tobacco leaf matured layer by layer and grew yellow. As for main economic traits and smoking quality, it performed better than the contrast variety. It was equivalent to the contrast variety about the appearance quality and physical characteristics of raw tobacco leaf. It displayed harmonious internal chemical components with lower nicotine content than the contrast variety. It performed a resistance to tobacco black shank and Tobacco Mosaic Virus (TMV), but susceptibility to Alternaria alternata (Fries) Keissler. It was expected that Eyan101 would produce greater economic effect by making a higher yield than other varieties.
