烤烟新品系品4 是雄性不育一代杂种。从1993 年开始观察试验,经过6 年的试验、示范,其间进行4 年4 次烟叶化学成分分析和全国评吸鉴定。试验、示范结果历年一致。该品系生育期与K326 无明显差异,农艺性状好,经济性状显著优于K326 ,需肥量中等,高抗气候斑点病,中抗花叶病,抗青枯病、赤星病和黑胫病。667 m2 产量、均价、667 m2 产值、上等烟率分别比K326 高17-28 kg、0-64 元/kg、174-55 元、5-59 % ,烟叶化学成分协调,香吃味与K326 相当,易烘烤,适应性较广。

Flue-cured tobacco new line 4 is a male sterile F1 hybrid. Observed from 1993 onwards, after 6 years of testing, demonstration, during which four years 4 times the chemical composition of tobacco leaves and the national assessment of the suck. Test, demonstration results consistent over the years. The line had no significant difference with K326 in its growth period. It had good agronomic characters and economic traits significantly better than K326. It needed medium fertilizer, high resistance to climate spot, middle anti-mosaic, anti-bacterial wilt, brown spot and black shank. 667 m2 output, the average price, the output value of 667 m2, the finest smoke rates were higher than the K326 17-28 kg, 0-64 yuan / kg, 174-55 yuan, 5-59%, the chemical composition of tobacco harmony, K326 quite easy to bake, more adaptable.
