- 摘要:
- 以22份辣椒品种为试材，对其11个植物学性状进行了聚类分析。结果表明：11个性状的变异系数为13.75%～138.12%，最大的是单果重，最小的是茎粗度；22份辣椒材料的遗传距离为1.036～7.618，根据遗传距离分类出了4个类群，第1类群包括11份材料；第2类群包括8份材料；8号遗传距离较远，单独归为第3类群；第4类群只有2份材料。
- Abstract:
- Taking 22 pepper cultivars as materials,eleven botanical characters were investigated,and clustering analysis were applied.The results showed that the coefficient of variation (CV) of 11 traits were 13.75% to 138.12%,the maximum CV was single fruit weight,the minimum was stem diameter.The genetic distance of 22 pepper cultivars was 1.036～7.618,all cultivars were clustered into four groups,the first group include 11 species,the second group include 8 species,‘No 8’with a distant relationship with other species,singly clustered into the third group,the fourth group only contain two species.
