烤烟新品种龙江981的选育及其特征特性

烤烟新品种龙江981系以龙江912作母本,CV87为父本,采用常规育种技术定向选育而成的烤烟新纯系品种。该品种植株结构合理,遗传性状稳定,田间生长势强,易烘烤。抗PVY,中抗赤星病、青枯病,中感黑胫病、TMV、CMV和根结线虫病。与对照品种NC89相比,烟叶产量、产值和均价分别提高16.78%、31.32%和13.28%,上等烟比例增加9.85个百分点。烤后原烟外观质量好,内在化学成分协调,烟叶质量符合中式卷烟需要,是一个品质、抗性、产量、适应性等方面较能兼顾的优良新品种。该品种适宜我国北方烟区种植。

烤烟新品种龙江981在黑龙江烟区的主要性状表现

[目的]分析烤烟新品种龙江981在黑龙江烟区的主要性状表现。[方法]以NC89为对照,从农艺性状、生育期性状、抗病性、经济性状、外观质量、化学成分和感官质量等方面,对由黑龙江种植的烤烟新品种龙江981进行了分析评价。[结果]在黑龙江烟区生态条件下,龙江981长势强、耐肥性好、易烘烤,抗PVY,中抗赤星病;产量、等级指数、产值指数分别比对照提高12.29%、11.76%、24.34%,上等烟比例增加5.40个百分点;外观质量较好。[结论]龙江981具有较稳定的农业经济效能和较高的农业应用性,钾含量、香气质、杂气和刺激性等需进一步改善或提升。

Main Characters of a New Flue-cured Tobacco Cultivar Longjiang 981 in Heilongjiang Tobacco-growing Area

[Objective] This study aimed to investigate the main characters of a new flue-cured tobacco cultivar Longjiang 981 in Heilong Tobacco-growing area. [Method]With NC89 as the control, the agronomic traits, growth period characters, disease resistance, economic characters, appearance quality, chemical composition and sensory quality of Longjiang 981 were analyzed and evaluated. [Result] Under the ecological conditions in Heilongjiang tobacco-growing area, Longjiang 981 showed robust growth, good fertilizer tolerance and good baking adaptability. It was resistant to PVY, and moderately resistant to brown spot disease. The yield, grade index and output value index of Longjiang 981 were higher than those of NC89 by 12.29%,11.76% and 24.34%, respectively. The proportion of superior tobacco was increased by 5.40%. In addition, Longjiang 981 had good appearance. [Conclusion] Longjiang981 has relatively stable agronomic traits and high agricultural application. However,its potassium content, aroma quality, odor and irritation need to be improved or enhanced further.
