1997～1998年参加全国区试6个烤烟新品种，试验结果表明，生育期与当地推广品种相当，抗病性能均较强。产量、产值、上等烟比例超过对照品种（NC89）的有“龙江915”和VA116。其它4个品种均未超过对照。经方差分析，品种间产量达到显著水平。产值、上等烟比例、均价无显著差异。原烟品质均较好，化学成分比例较协调，经评吸，香吃味和NC89接近，有较好的使用价值。 From 1997 to 1998, we took part in 6 new tobacco varieties tested in the national district. The results showed that the growth period was similar to the local varieties, and the disease resistance was strong. Output, output value, superior tobacco than the control varieties (NC89) have “Longjiang 915” and VA116. The other four varieties did not exceed the control. After variance analysis, the yield between varieties reached a significant level. Output value, the proportion of superior tobacco, the average price was no significant difference. The quality of raw tobacco are better, the proportion of chemical components than the coordination, the assessment of smoking, smell and eating close to NC89, a better value.
