本文分析了南京早椒（ＣａｐｓｉｃｕｍｆｒｕｔｅｓｃｅｎｓＬ．ｖａｒ．ＣｏｎｏｉｄｅｅｓＢａｉｌｅｙ）和Ｃ．ｃｈｉｎｅｎｓｅ二亲本及Ｆ１杂种花粉母细胞减数分裂终变期和中期Ｉ染色体配对的构型。结果表明：二亲本花粉母细胞减数分裂染色体配对均正常，为１２个二价体（双单倍体２ｎ＝２４）。Ｆ１杂种花粉母细胞减数分裂染色体配对很不规则。其平均频率分别为单价体０．０３６，二价体９．１８，三价体０．０３６，四价体０．８０，六价体０．３８。南京早椒和Ｃ．ｃｈｉｎｅｎｓｅ染色体间存在着相互易位，因此，二亲本间彼此有差异。单价体出现极少，这可断定南京早椒与Ｃ．ｃｈｉｎｅｎｓｅ染色体间是部分同源的，但染色体组结构上存在着差异。由于染色体结构上差异，所以Ｆ１杂种的育性较低。
This paper analyzes the Nanjing pepper (CapsicumfrutescensL.var.ConoideesBailey) and C. Chromosome pairing between the metaphase and metaphase meiosis of chinense daughters and F1 hybrid pollen mother cells. The results showed that the meiosis chromosomes of two parents were normal, which was 12 bivalents (double haploid 2n = 24). F1 hybrid pollen mother cell meiosis chromosome pairing is very irregular. The average frequencies were 0.036 for monovalent, 9.18 for divalent, 0.036 for trivalent, 0.80 for tetravalent and 0.38 for hexavalent. Nanjing pepper and C. There are reciprocal translocations between the chinense chromosomes, so the parents are different from each other. Monovalent body appeared very little, which can conclude that Nanjing early pepper and C. Chinense chromosomes are partially homologous, but there are differences in the chromosomal structure. F1 hybrids have low fertility because of their structural differences.
