灰色关联度对香料烟品种资源的综合评估

Comprehensive Evaluation of Oriental Tobacco Varieties by Grey Correlation Analysis

为了克服仅从单一性状评价香料烟品种资源的局限性,采用了灰色关联度分析法对15份香料烟品种资源进行综合评估。结果表明,波贝达2-2、里拉544,BS4号、巴斯玛略维纳、丸叶、巴斯玛4号、依兹密尔12、巴斯玛11号品种间的灰色关联度均超过对照品种柯玛蒂尼。不同性状与原烟产量的关联度也不同,其关联序列为:叶数>中部叶大小>下部叶大小>株高>上部叶大小。这一结果与田间选择的结果有很高的一致性。

In order to overcome the limitation of the evaluation of a single trait of oriental tobacco vailety resource, grey correlation analysis was employed to comprehensively evaluate 15 varieties of oriental tobacco. The results showed that the grey correlations of Pobeda 2-2, Rila-544, BS4, Basma Liovina, Maru, Basma 4, Izmir 12 and Basma 11 were superior to CK. The correlations between different traits and yields were different, the sequence was leaves 〉 central leaf size 〉 inferior leaf size 〉 height 〉 upper leaf size of tobacco.
