摘要
以5份中国古老月季品种、3份野生蔷薇和22份现代月季品种为试材,采用常规人工授粉杂交方法,同时结合花粉活力及倍性测定情况,研究了古老月季远缘和品种间的杂交亲和性,筛选出了高亲和性的杂交亲本,以期为中国古老月季的杂交育种、亲本选择提供参考依据。结果表明:古老月季品种间杂交亲和性最高,所配组合的杂交成功率达87.50%,古老月季与野生蔷薇、现代月季的远缘杂交亲和性也较高,所配组合的杂交成功率均高于50%,说明古老月季远缘和品种间的杂交亲和性均较好,因此,在杂交工作中,选用古老月季作为亲本材料有较好的杂交亲和效果;古老月季杂交亲和性与花粉活力、亲本倍性,正反交等因素相关,选择月季亲本时要综合考虑各因素,以提高月季杂交的成功率;结合远缘杂交、品种间杂交以及人工授粉结实情况,筛选出适合做母本的古老月季品种为"大花香水""小花香水""月月红",适合做父本的月季品种为"金樱子""可爱的绿"。
5 old Chinese rose cultivars,3 wild rose cultivars and 22 modern rose cultivars were used as test materials.Using conventional artificial pollination hybridization methods,combined with pollen vigor and ploidy determination,the hybrid compatibility between old Chinese rose distant relatives and varieties were studied,and high-affinity hybrid parents were screened out,in order to provide a reference for the hybridization breeding and parent selection of old Chinese roses.The results showed that the hybridization compatibility among old Chinese rose varieties was the highest,the hybridization success rate of the matched combinations was 87.50%,the distant hybridization compatibility between old Chinese rose,wild rose and modern rose was higher,and the hybridization success rates of the matched combination was higher than 50%,indicating that the distant hybri dization compatibility and the hybridization compatibility between old Chinese rose varieties were better.Therefore,in hybridization,selecting old Chinese rose as parent material had better hybridization compatibility effect.The hybridization compatibility of old Chinese rose was related to pollen vigor,parental ploidy,positive and negative cross,etc.All factors should be taken into consideration when selecting rose parents to improve the success rate of rose hybridization.Combining with the result of artificial pollination,interspecific hybridization and distant hybridization,the cultivars could be used as female parents of Rosa odorata var.gigantea,Rosa‘Xiao Hua Xiang Shui’and Rosa chinensis Jacq.,Rosa laevigata Michx.and Rosa‘Lovely Green’could be used as male parents.
