| 摘 要： | 本文对黑龙江省栽培的黑穗醋栗(Ribes migrum L)两个品种,即厚皮长穗和薄皮黑豆,进行了核型分析。其染色体数目均为2n=2x=16,核型公式为2n=16=16m,核型均由中部着丝点染色体组成,均具有一对随体,文中并对起源问题进行了讨论。

| Abstract: | The karyotypes of two cultivars(Houpichangsui and Baopiheidou)of the black currant(Ribes nigrum L.)are studied in the paper.The chromosome number of each karyotype is2n=2x=16.The karyotype formula is 2n=16=16m.All chromosomes of both karyotypesare mediocentric.There is one pair of satellite chromosomes in them.The origin of these twocultivars is also discussed. |
