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.
