Pei’ai 64S is the female parent and R981(Guang 1) is the male parent of Peiliang You 981. Thehybrid showed its characters of high and stable yieldand wide adaptability in the variety trials anddemonstration production in the recent years,and itwas released in March 2002 by Hunan Crop VarietiesRelease Committee.Grain展开更多

[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
