The Adaptability Of Different Ecological Regions In Yunnan Flue-cured Tobacco Varieties

Combined with Hunan ZhongYan brand material requirement,2010-2011 in Yunnan based on the existing main variety of each region, through the introduction, demonstration and promotion had the potential to produce high quality variety resources, combining quality analysis, from two aspects of ecological adaptability and industrial availability to the demonstration and selection of flue-cured tobacco varieties, in order to optimize the Hunan ZhongYan layout base unit of varieties to provide guidance.Of this study was to test the stationing in Kunming, Yunnan province, Dali and Quj ing city of 11 (state), for the introduction of varieties, the United States imported varieties and 3 the 19 categories of flue-cured tobacco varieties bred varieties such as agriculture experiment and demonstration research, respectively through the stages of investigation, analysis of agronomic and economic characters and quality of tobacco leaf usability evaluation study of each type, and draw the following conclusion:1, Based on the different development stages of the new flue-cured tobacco varieties were investigated, studied the characteristics of the ecological environment, the results show that the clouds, clouds, clouds,99 98 98, T29 growth period is longer, more than 130 days, T66, clouds, clouds,96 96 growth period short, under 125 days; Over 109 in more than 80 days from transplanting to foot leaf maturity, belongs to the late varieties, NC471 under 67 days from transplanting to foot leaf maturity, belongs to the early maturity varieties;2, Through the new flue-cured tobacco varieties agronomic traits (biological and economic characters), the results show that the highest T66, T29 plant height, effective; the maximum number of blades Clouds, clouds,109,98 plant height is the most short, clouds, clouds 109 effective leaf number at least 99; T66 pitch, the largest 109 minimum pitch clouds; T66, NC196 area yield and highest MuChanZhi, clouds 115 area yield and MuChanZhi minimum.3, Through to the immanent quality of tobacco leaf (chemical analysis) and sensory quality of comprehensive quality evaluation, the results show that the chemical composition was more appropriate is over 115 and over 99 varieties, incongruously varieties mainly NC102, T29; Sensory quality evaluation is KRK26 good varieties, over 99, T29, NC297, sensory evaluation is a bit poor varieties is over 105,113,100, T66 clouds, clouds H3.4, After 2 years of experiment and demonstration of new varieties of research, combined with Hunan ZhongYan brand requirements, find out the ecological adaptability and applicability of the flue-cured tobacco varieties, clear the different cultural characteristics and the application value and maximum genetic potential, screening of flue-cured tobacco’s main varieties adapted to different ecological regions in yunnan, back-up varieties 1-2, the results can be as Hunan ZhongYan materials security requirements of varieties, reasonable layout and use provides the reference basis.
