烤烟新品种主要数量性状与产量产值的灰色关联分析

Grey Correlation Analysis of Main Quantitative Traits and Yields and Output Value of New Flue-cured Tobacco Varieties

运用灰色关联分析方法对湖南新引的烤烟品种进行了主要数量性状与产量产值间的分析以及品种间的比较。结果表明,对各烤烟品种产量和产值影响较大的因素是上中等烟比例和上部烟叶的开片度,各个因素对产量的影响程度依次为:上中等烟比例>上部叶开片度>株高>节距>茎围>中部叶面积>叶片数;对产值的影响程度依次为:上中等烟比例>上部叶开片度>株高>节距>中部叶面积>茎围>叶片数。新引烤烟品种与对照品种的关联程度最大的是贵烟4号,关联度达到了0.8257;各个品种与对照关联的排列顺序为:贵烟4号>云烟97>中烟201>粤烟97>HY-9-7>南江3号>KRK 26>K 326。

Main quantitative traits and yields and output value of newly introduced flue-cured tobacco varieties were analyzed and compared by grey correlation analysis,and the results showed that： the proportion of superior-middle grade tobacco and the leaf width with length proportion were the bigger influence factors to yield and output value,and the influence degree to yields of every factor was as follows： the proportion of superior-middle grade tobaccothe leaf width with length proportionplant heightinternodes＇ lengthstalk circumferencearea of middle leafleaf number,while to output value was as follows： the proportion of superior-middle grade tobaccothe leaf width with length proportionthe plant heightinternodes＇ lengtharea of middle leafstalk circumferenceleaf number.The greatest relational degree between new varieties and CK was Guiyan 4,which was 0.8257,and the sequence for all varieties was Guiyan 4Yunyan 97Zhongyan 201Yueyan 97HY-9-7Nanjiang 3KRK26K326.
