牡丹品种间杂交亲和性分析

摘要

In the test,using the method of Cross-pollination to discuss the hybridization affinity among tree peony varieties.Taking 'FengDan' and 'Zibanmudan' as the female parent,developing 13 varieties hybrid combinations,and taking single rosette seed quantity as the evaluation indicator of affinity,the results showed that taking 'FengDan' as the female parent,13 male varieties that selected were all affinity to hybrid with 'FengDan',however,the affinity of different paternal species had big difference,and the affinity of 'Wulongpengsheng'was the highest;taking 'Zibanmudan' as the female parent,12 male varieties that selected were all affinity to hybrid with 'FengDan' except 'Yinhongqiaodui',However,also the affinity of different paternal species had big difference, the affinity of 'Qingchun' was the highest;By determination of pollen viability and analysis of hybrid combinations,paternal pollen viability had some effect on the hybrid sterility,but not significant.%采用杂交授粉方法对牡丹品种间杂交的亲和性进行探索,分别以‘凤丹’和‘紫斑牡丹’作母本,共开展了13个品种间的杂交组合,以单花结种量作为亲和性的评价指标。结果表明：以‘凤丹’做母本时,所选的13个父本品种与‘凤丹’杂交均亲和,但不同的父本品种的亲和性有很大的差异,其中父本‘乌龙捧盛’亲和性最高;以紫斑牡丹做母本时,所选的13个父本品种除了‘银红巧对’表现不亲和,其它12个品种均亲和,但不同的父本品种的亲和性也存在差异,其中父本‘青春’亲和性最高;通过花粉活力测定及杂交组合分析,父本花粉活力对杂交育性有一定影响,但不显著。
