【摘要】 为了解晒晾烟种质资源之间的相似性,研究了32个晒晾烟品种资源在湖北省十堰市丹江口地区的农艺性状、经济性状、品质性状,根据19个性状数据进行了系统的聚类分析。结果表明,引进的晒晾烟品种资源可分为4个类群:品种类群Ⅰ包括半铁泡、大宁旱烟、四川晒烟、武鸣牛利、铁杆子5个品种;品种类群Ⅱ包括石门小铁板、天池乌烟等12个品种;品种类群Ⅲ包括GQH(川渝中烟提供)、大集大铁板烟等12个品种;品种类群Ⅳ包括公会晒黄烟(深色)、公会晒黄烟(浅色)、湖南宁乡晒烟3个品种。综合农艺性状、经济性状和品质性状分析,认为品种类群Ⅳ属于烟株高大、生育期较长、经济性状较好、化学成分较为协调的优良晒晾烟品种资源类群,可进一步示范推广。更多还原

【Abstract】 In order to find out the similarity among sun-cured tobacco germplasm, 32 sun-cured tobacco cultivars from China were investigated by cluster analysis based on data of 19 traits in Danjiangkou district, Shiyan city of Hubei province. Results showed that 32 sun-cured tobacco cultivars could be clustered into 4 groups. Group I contained Bantiepao, Daning tobacco, Sichuan sun-cured tobacco, Wumingniuli, Tieganzi Group II contained 12 varieties, including Shimenxiaotieban, Tianchiwuyan et al, Group III contained 12 varieties such as GQH(provided by China Tobacco Chuanyu Industrial CO., LTD), Dajidatieban tobacco et al. Group IV contained Gonghui yellow sun-cured tobacco(dark color), Gonghui yellow suncured tobacco(light color), Hunan ningxiang sun-cured tobacco. Based on the analysis of agronomic characters, economic characters and quality traits, group IV was the best of all, worth for further demonstration and popularization.更多还原
