摘要: 掌叶覆盆子(Rubus chingii Hu),蔷薇科悬钩子属,未成熟果实入药,成熟果实营养丰富,是优质的“药食同源”特色植物,经济效益显著。为突破育种瓶颈,尽快提升覆盆子品质,急需开发分子标记辅助育种。以前期筛选的17个掌叶覆盆子优质株系和7个其他悬钩子属植物[山莓(Rubus corchorifolius)、三花悬钩子(Rubus trianthus)、茅莓(Rubus parvifolius)、高粱泡(Rubus lambertianus)和光滑悬钩子(Rubus tsangii)、黑莓‘赫尔'(Rubus fructicosus var. Hull)和重瓣空心泡(Rubus rosifolius var. coronarius)]为材料,筛选适合掌叶覆盆子种间和种内鉴别的RAPD引物。结果表明,25条RAPD引物扩增条带清晰,该方法重复性好,能明显区分掌叶覆盆子和其他悬钩子属植物;其中6条可区分掌叶覆盆子不同株系。

Abstract: Rubus chingii Hu, belongs to Rubus, Rosaceae. Its unripe fruit is used as medicine material, and its ripe fruit is rich in nutritions. Rubus chingii is a unique dual-function food with remarkable nutraceutical, pharmaceutical and economic values. It is urgent to develop molecular marker-assisted breeding and then comprehensively improve the quality of Rubus chingii fruit. Seventeen accessions of screened Rubus chingii seedlings with good traits and seven other Rubus plants, including Rubus corchorifolius,Rubus trianthus,Rubus parvifolius,Rubus lambertianus, Rubus tsangii, as well as Rubus fructicosus var. Hull and Rubus rosifolius var. coronarius, were used as materials, to select the optimal RAPD primers for intraspecial and interspecific genetic diversity analysis for Rubus chingii. The results showed 25 primers with products of clear bands and good repeatability could be used to identify the Rubus chingii seedlings and other Rubus plants. Furthermore, six primers could be applied for distinguishing different genotypes of Rubus chingii.

Key words: Rubus chingii Hu, Rubus, molecular marker, random amplified polymorphic DNA
