白肋烟品种鄂烟3号的选育及特征特性

Breeding and Characteristics of Burley cv.HubeiT3

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.

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.
