白肋烟品种对比试验

为筛选更适合重庆市万州地区的优良品种,本试验通过对6个白肋烟品种进行田间对比试验。结果表明:1)除品种达白1号和达白2号生育期比对照稍迟外,其余品种的生育期与CK相当,达白1号、50927、9026、106126的生长势强于CK,各品种的株高和叶数均高于CK。2)从抗病性看,50927和9026病害发生于CK相当,其余品种抗病性均优于CK。3)以品种50927产量最高,为180.13kg/667m2,其次是106126;以品种9026产值最高,为2224.68元/667m2,其次是50927;上中等烟比例以达白2号最高。4)从农艺性状和经济性状的多方面比较分析,50927、9026和106126较适宜于在万州进行进一步的扩大示范,以筛选适合万州生态、生产条件的白肋烟品种。

Varieties Comparative Test Research of Burley Tobacco

In order to screen the more suitable tobacco varieties for the Wanzhou area, this experiment carries out field comparison test for seven varieties of burley tobacco. The results showed that: (1) In addition to the growth period of varieties of Dabai No. 1 and Dabai No. 2 is a little later than CK, the growth period of the remaining species is correspond to the CK. Growth vigor of Dabai No. 1, 50927, 9026 and 106126 is stronger than CK. Plant height and leave numbers of all varieties are higher than CK. (2) As for the resistance of disease, 50927 and 9026 disease occurred is the same as CK. The remaining varieties are better than CK. (3) As for yield, varieties 50927 is the highest 180.13kg / mu, followed by 106 126; as for output value, 9026 is the highest 2224.68 yuan / mu, followed by 50 927; as for quality , Dabai No.2 is the highest with the biggest ratio of upper-middle class tobacco. (4) Throughout the comparative analysis for the aspects of agronomic and economic traits, 50927,9026 and 106 126 are more appropriate to be expanded further in the Wanzhou so that we can screen burley tobacco varieties which is more suitable planted in the Wanzhou ecological and production conditions.
