Octoploidy was induced in Chili pepper (Capsicum annuum cultivar 'cerasiformis') through the application of colchicine and the cytomorphological features of two octoploid plants were described. In general, the octoploids did not exhibit gigas characters when compared to the tetraploids; on the contrary they were less vigorous, suggesting that the optimum and desirable ploidy level for Capsicum is probably tetraploid. Chromosome associations such as octovalents and hexavalents, in addition to IVs, IIIs, IIs and Is, were recorded at diakinesis and metaphase I. Meiosis was highly irregular and the pollen and seed fertility was very low. Cytological features of octoploid Chili peppers are compared with octoploids of Physalis and Petunia.
八倍体通过秋水仙素的应用在辣椒（Capsicum annuum 栽培品种 'cerasiformis'）中被诱导，描述了两个八倍体植物的细胞形态特征。总的来说，与四倍体相比，八倍体并没有表现出巨大的特征；相反，它们的活力较低，这表明辣椒的最佳和理想的倍性水平可能是四倍体。在减数分裂前期和中期，除了 IVs、IIIs、IIs 和 Is 外，还记录了八价体和六价体等染色体联合。减数分裂高度不规则，花粉和种子的育性非常低。八倍体辣椒的细胞学特征与黄灯笼和矮牵牛的八倍体进行了比较。
