以MSTN86为母本、LAB21为父本于1998年育成了白肋烟雄性不育杂交种鄂烟3号,并于1999~2004年进行了品比试验和生产示范。结果表明:该品种株式筒型,打顶株高127.1cm,可采收叶22~24片,叶形椭圆,叶色黄绿,着叶均匀,田间生长旺盛。大田生育期90d左右,抗病性较强、适宜种植范围较广,平均产量2380.2kg/hm2,均价5.26元/kg,上等烟20.47%,产值12462.18元/hm2,均高于对照(鄂烟1号)。其原烟近红黄色,弹性强,光泽鲜明,结构疏松,厚薄适中,外观质量优于对照。化学成分含量适宜、比例协调,烟碱含量明显低于对照。白肋烟香型风格较显著,香气质较好,香气量较足,浓度较浓,劲头适中,评吸质量均优于对照。
Using MSTN86 as the female parent and LAB21 as the male parent, a male sterility hybrid, Eyan 3 of Burley tobacco was bred in 1998, and the ratio test and production demonstration were conducted from 1999 to 2004. The results showed that the strain was of cylinder type with a top height of 127.1 cm and 22-24 leaves were harvested. The leaf shape was oval, the leaf color was yellow-green, the leaf was uniform and the field was vigorous. The average growth rate was 2380.2kg / hm2, the average price was 5.26yuan / kg, the finest smoke was 20.47% and the output value was 12,462.18yuan / hm2, which were higher than that of the control Smoke No. 1). The original smoke near red and yellow, flexible, shiny, loose structure, moderate thickness, the appearance of quality is better than the control. Appropriate content of chemical composition, the proportion of coordination, nicotine content was significantly lower than the control. Burley flavor more significant flavor, good aroma, aroma more adequate, the concentration of strong, moderate momentum, smoking quality are better than the control.
