摘要：

中国古老月季是培育月季新品种重要的基因资源。分析其杂交亲和性,有助于中国古老月季品种在月季新品种选育中的应用。本研究历时4年以18个中国古老月季为亲本之一,与现代月季及少数野生蔷薇进行人工杂交授粉,统计结实及发芽率,分析其杂交结实特性。结果表明,散粉量多的品种有6个,分别为‘大富贵’、‘思春’、‘一品朱衣’、‘月月粉’、‘紫红香’、‘紫香绒’;离体花粉萌发率偏低,20%以上的品种有‘玉玲珑’、‘一品朱衣’、‘月月粉’、‘紫香绒’、‘大富贵’、‘思春’、‘葡萄红’。共配置杂交组合285个,杂交1190朵花,结实271朵,结实率为22.77%,获得4744粒种子,1833粒发芽,发芽率为38.64%。综合分析发现,‘大富贵’、‘葡萄红’、‘软香红’、‘思春’、‘一品朱衣’、‘云蒸霞蔚’、‘紫红香’、‘紫香绒’8个品种结实性较高,易获得杂交后代。

Abstract:

Chinese old garden roses were crucial genetic resource for new varieties breeding and selection. The cross compatibility was analyzed, which can be useful for the application of new rose varieties breeding and selection in Chinese old garden roses. In our study, interspecific hybridization characteristics (seedlings and germination rate) were analyzed by using artificial hybridization, which were selected 18 Chinese old garden roses as one of the crossing parent with modern roses or few wild roses for 4 years. 6 varieties had more powder scattering, including ‘Dafugui’, ‘Sichun’, ‘Yipinzhuyi’, ‘Parson’s Pink China’, ‘Zihongxiang’ and ‘Zixiangrong’. The pollen germination rate in vitro was low, varieties with the rate above 20% included ‘Yulinglong’, ‘Yipinzhuyi’, ‘Parson’s Pink China’, ‘Zixiangrong’, ‘Dafugui’, ‘Sichun’ and ‘Putaohong’. Totally, 285 hybrid combinations were carried out, which had 1190 flowers, 271 seedlings and the seed setting rate was 22.77%. Meanwhile, 1833 of all the 4744 seeds germinated (38.64%). The results indicated that 8 varieties of ‘Dafugui’, ‘Putaohong’, ‘Ruanxianghong’, ‘Sichun’, ‘Yipinzhuyi’, ‘Yunzhengxiawei’, ‘Zihongxiang’ and ‘Zixiangrong’ had high seed setting ability and their F1 hybrids could be easily obtained.
