白肋烟品种鄂烟3号的选育及特征特性

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。

Breeding and Characteristics of Burley cv. HubeiT3

The Burley tobacco,HubeiT3,a male-sterile hybrid seed from mother MSTN86 and father LAB21 was bred in 1998.The results of experiments during 1999-2004 showed that HubeiT3 characterized a cylindrical plant shape with evenly spaced yellowish green oval leaves,topped height of 127.1cm,22-24 available leaves, vigorously grew in field during growing period around 90 days,relatively high resistance to disease and good adaptability.The average yield,output value and price were 2380.2kg/ha,12462.18 RMB yuan/ha and 5.26 RMB yuan/kg,respectively; and the percentage of high grade leaves was 20.47%;which were higher than those of the contrast,cv.HubeiT1.The cured leaf of HubeiT3 was reddish brown,bright and clear,possessed good elasticity and open structure;whose(apparent) quality was better than that of HubeiT1.The nicotine content and ratio of N and nicotine in HubeiT3 was(4.19%) and 0.99 in upper leaves and 3.50% and 0.98 in middle leaves, respectively.With relatively distinct style of burley tobacco,higher flavor quality,amplitude and concentration,moderate strength,and harmonious chemical constituents,the smoking quality of HubeiT3 was superior to HubeiT1.
