摘要： 8个从美国、巴西引进的烤烟新品种，经检疫合格后在大田进行品种比较试验，对照为K326。试验结果表明：除OX414属多叶型的品种，栽后68d现蕾外，其他品种现蕾期、中心花开放期等与对照相近。各品种都没发黑胫病和根结线虫病，赤星病和TMV较轻。公顷产量最高的是OX414，其次是NC72“Primed”，第三是NC71。公顷产值最高的是K326，其次是OX414，NC72“Primed”第三，这些品种间无显著差异。NC100、K326、NC72“Primed”等品种上等烟比例、均价、级指和产指4号较高。综合起来看，OX414产量高，K326、NC100、NC71公顷产值、上等烟、均价、级指等较高。COM烟和RGH61各项经济指标都较低。

Abstract: 8 flue-cured tobacco varieties compare test were carried out in the field after quarantine, and the varieties were introduced from Brazil and American. The comparison variety is K326. The results showed that the new flue-cured tobacco varieties of bud were the same as K326 except OX414 later. OX414 belong no flowing variety. All new varieties are free to blank shank and tobacco root nematode, and light infected Brown spot and TMV. OX414 has the highest yield, the next is NC72 “Primed”, the third is NC71. K326 has the highest Hectare production value, OX414 is the next, NC72 “Primed” is the third, and there was no remarkable difference between these new varieties. K326, NC100, NC72 “Primed” have the higher qualities and grade index. On the whole, K326, OX414, NC100, NC72 “Primed” are very good at yield, qualities, Hectare production value, grade index. But all of the economic index of Com and RGH61 are low.
