摘要: 本文对四川农业大学引种栽培的墨西哥辣椒(C. annuum var. peper chili Jaiepeno)的核型进行了分析;其核型公式为:2n=2x=24=22m+2sm,2A核型,平均臂比1.24,染色体长度比1.40。与国产的7个辣椒品种的核型进行了比较,发现其核型与国产辣椒有较大差异,似为亲缘关系较远的另一变种。并根据核型对其起源作了讨论。

关键词: 辣椒, 核型, 起源

Abstract: The studies treated the karyotype of C. annuum var. peper chili Jaiepeno, which is the adventions plant coming from U. S. America and planted by Agricultural University Sichuan, The karyotypic formula is K (2n)=24=22m+2sm, the karyotype belonging 2A type. Based on the karyotypc compares with 7 varieties of Capsicum annuum in China, the origin of species and evolution of the variety is also discussed here.

Key words: CAPSICUM FRUTESCENS, KARYOTYPE, ORIGINS
