NC196于2009年从美国金叶种子公司引进,2012-2013年在全国9个省(市)进行田间小区试验,并进行抗性分子标记检测及人工接种鉴定。结果表明,该品种含有Ph基因、抗黑胫病(0号);无抗烟草普通花叶病(TMV)的N基因、但中抗TMV,抗性来自其他抗原;有感马铃薯Y病毒(PVY)的Va基因、感PVY;中抗青枯病、中感根结线虫病和赤星病。该品种株型塔形,叶片长椭圆形。南方烟区,有效叶数21片,生育期115 d;北方烟区,有效叶数23片,生育期123 d。NC196综合经济性状与对照品种K326、NC89相当,整体外观质量优于对照品种K326,主要化学成分含量与对照品种K326、NC89相近,协调性好。原烟烟叶质量档次中等偏上,整体吸食品质与对照品种K326相当。2014年通过全国烟草品种审定委员会农业评审。
NC196 was introduced from American Golden Leaf Seed Company in 2009. From 2012 to 2013, field trials were carried out in 9 provinces (cities) in the country, and resistance marker detection and artificial inoculation were carried out. The results showed that this cultivar contains Ph gene, anti-shank disease (No.0), N gene without anti-tobacco mosaic disease (TMV) but anti-TMV and resistance derived from other antigens, and PVY ) Va gene, sense of PVY; resistance to bacterial wilt, the sense of root knot nematode disease and brown spot disease. The plant type tower, leaves oblong. Southern tobacco area, the effective number of leaves 21, the growth period of 115 d; northern tobacco area, the effective number of leaves 23, the growth period of 123 d. NC196 comprehensive economic traits and control varieties K326, NC89, the overall appearance quality is better than the control variety K326, the main chemical composition and control varieties K326, NC89 similar, good coordination. The quality of the original tobacco leaf was moderately high, and the overall smoking quality was comparable to that of the control variety K326. In 2014, it passed the agricultural assessment of the National Tobacco Variety Approval Committee.
