【摘要】 烤烟新品种龙江911(9111-21)是以龙江851(Windel)为母本,以CV91为父本杂交,系谱法选育而成,2000年12月通过全国烟草品种审定委员会审定。经多年多点试验,其主要农艺性状遗传稳定,田间生长整齐一致,田间自然株高140～160cm,打顶株高95～105cm,有效叶数19～21片,腰叶长62.3cm,腰叶宽26.3cm,叶形长椭圆,叶面稍皱,叶片厚薄适中,着生均匀。花序离散,花色淡红色。田间生长势较强,大田生育期111～115d,抗赤星病,中抗黑胫病、根结线虫病、PVY,中感TMV。耐肥性好,叶片落黄成熟快,早熟,易烤。烤后原烟“金黄到深黄”,油分“较多”,色度“强到浓”,结构尚疏松。还原糖平均含量20.3%,总糖24.4%,烟碱2.33%,总氮1.79%,蛋白质8.64%,钾含量为1.45%,主要成分含量适宜,内在化学成分协调。平均产量2755.5kg/hm2左右,均价5.79元/kg,上等烟27.0%,产值16390.86元/hm2。综合性状优于NC89。到2001年底已经累计种植近2万hm2。更多还原

【Abstract】 LJ911(9111-21),a new flue-cured tobacco variety was developed from the cross between LJ851(Windel)and CV91,passed the evaluation of National Tobacco Variety Evaluation Committee in December,2000.Most agronomic traits of LJ911were stable and uniform in the test of several years in different loca-tions.The plant height of LJ911was from140cm to160cm,topping height was from95cm to105cm,the number of harvestable leaves was from19to21and their distribution on the stalk was even.The length of middle leaf was62.3cm with26.3cm in width,and the leaves shape was long elliptical with slightly wrinkle,and the body was medium.The color of flower was light red,and flowers lines were scattered.LJ911grew normally,the growing period in field lasted from111to115days.LJ911was resistant to brown spots,moderately resistant to black shank,root knot,and PVY,while moderately susceptible to TMV.It had good tolerance to abundant fertilization.The leaves yellowed and ripened well and early,and were easy to cure.Cured leaves were″gold-yellow to deep-yellow″,and had much oil,their color degree was″strong to rich″and their texture was a little loose.The chemical components analysis of the cured leaves was as follows:the content of reducing sugar,total sugar,nicotine,total nitrogen,protein and potas-sium was20.3%,24.4%,2.33%,1.79%,8.64%,1.49%respectively,and the content and ratio of major chemical components were suitable.The average yield was2755.5kg /hm 2 ,the average price was5.79yuan/kg,high-class leaves ratio was27.0%,and the out put value was16390.86元/hm 2 .Its synthetic charac-teristics were superior to NC89,and the growing area has reached200000hm 2 by the end of2001.更多还原
