中烟103是从红花大金元中获得变异株,经系统选育而成的。该品种植株结构合理,遗传性状稳定,田间长势强,易烘烤;耐TMV、CMV、PVY,中抗黑胫病,气候斑点病轻,中感根结线虫病,感青枯病和赤星病;其主要经济性状比对照品种NC89、K326或红花大金元有不同程度的提高;烤后原烟橘黄色烟比例高,结构疏松,身份中等,油分有-多,色度强-浓,外观品质总体性状优于对照品种K326;化学成分含量适宜,比例协调,与对照品种K326相比,糖、钾含量略高,烟碱、总氮含量略低。感官评吸与K326质量档次相当。中烟103是一个质量、产量、抗病较能兼顾的具有红花大金元香气特征的烤烟新品种,2007年通过全国烟草品种审定委员会审定。
China Tobacco 103 was obtained from safflower Daikin yuan variant strains, the system of breeding. The variety has the advantages of reasonable structure, stable genetic traits, strong field growth and easy to roast; TMV, CMV, PVY, anti-black shank disease, light climate spot, root knot nematode, bacterial wilt and brown spot ; The main economic traits than the control varieties NC89, K326 or safflower Daikin yuan increased to varying degrees; roasted orange smoke after the original tobacco a high proportion of loose structure, medium identity, oil has - more, strong color - rich, The overall quality of appearance quality was better than that of the control variety K326. The content of chemical components was suitable and the proportion was coordinated. Compared with K326, the content of sugar and potassium was slightly higher and nicotine and total nitrogen content was slightly lower. Sensory evaluation and K326 quality grade equivalent. China Tobacco 103 is a new type of flue-cured tobacco with the characteristics of safflower Daikin-yuan aroma, yield, disease resistance and more. It was approved by the National Tobacco Variety Approval Committee in 2007.
