摘要
韭菜坪2号是通过对烤烟品种G28在大田生产中叶片数、叶片大小和抗病性变异单株的选择而成功培育出的烤烟新品种。韭菜坪2号大田生育期为135-142d，田间生长整齐；高抗气候斑点病，抗病能力较强；产量、产值、均价、上等烟率、中等烟率分别比对照K326增加7．25kg／667m^2、59．58元／667m^2、0．06元／kg、0．5百分点、0．31百分点；增加率分别为5．33％、5．73％、0．73％、2．28％、0．66％。烟叶外观质量较好，化学成分协调；评吸质量总体较好，总体略好于对照K326。韭菜坪2号区域性较强，适应范围较窄，适宜在海拔1400-1900m的高海拔烟区种植。
Jiucaiping 2, a new tobacco variety, was bred from the mutant of G28 variety in 2002 and was approved by Guizhou Tobacco Variety Examination Committee in March, 2009. The growth period of Jiucaiping 2 with identical growth and strong disease resistance is 135 to 142 d and its yield, output value, mean price, rate of first-class tobacco leaf and rate of middle-class tobacco leaf increases by 7.25 kg/667m^2 , 59.58 Yuan/667m^2 , 0.06 Yuan/kg, 0.5% and 0.31% and the increase rate is 5.33%, 5.73%, 0.73%, 2.28% and 0.66% compared with K326 respectively. The smoking quality of Jiucaiping 2 with good appearance and harmony chemical composition is slightly better than K326 in general. Jiucaiping 2 with strong regional characteristic should be planted in the tobacco planting areas with 1400 to 1900 meters above sea level.
