摘  要:
2008~2009年在湖南石门,运用系统聚类法,对从各地收集的15份烤烟种质的农艺性状进行了聚类分析,结果表明:15份烟草种质可划分为2个品种群和4个亚群,其中品种群包括12个品种,占80%,品种群包括3个品种,占20%。对各品种群及亚群的农艺性状进行了综合评价,结果显示:品种群的株高、节距、腰叶长和腰叶宽均比品种群大,单株产量和茎围相差不大,而有效叶数则比品种群少,移栽至现蕾所需的天数也较少,且品种群中亚群单株产量比品种群各亚群都要高。

摘  要:
Cluster Analysis on agronomic characters of 15 tobacco germplasm resources was conducted in Shimen, Hunan in 2008~2009. The results indicated that 15 tobacco germplasm resources could be clustered into 2 groups and 4 subgroups. Group Ⅰ included 12 species, accounted for 80%, and groups Ⅱ included 3 species, accounted for 20%. In addition, the comprehensive evaluation on agronomic characters of groups and sub-groups was carried out and the result showed that compared to group Ⅰ, the plant height, distance of knot, length and width of central leaves group Ⅱ were bigger while the number of effective leaves and the days from transplanting to flower bud appearance were less. Differences in yield per plant and stalk circumference between two groups were not clear. While yield per plant of subgroup Ⅰ of group Ⅱ was more than that of all subgroups of group Ⅰ.
