[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.展开更多

The results showed that Longjiang No.237, immune to TMV, grew strongly, with a long growth term, and had low demands on nitrogen.Besides, Longjiang237 takes advantages in terms of yield, grade index and output value index, which grew by 10.46%, 8.00% and 18.41%, respectively. Additionally,highlights should be given to potassium, aroma quality, odor, strength, irritation, and aftertaste of tobaccos.展开更多
