Abstract：With Viburnum macrocephalum‘Taishan’ as female parent and Viburnum dilatatum ‘Dina’ as male parent , the distant hybridization was carried out to study the compatibility of distant hybridization .Six different pollination methods were used , and the common pollination method was used as control .The results showed that the fruiting rate of duplicate pollination was the highest among the 6 pollination methods , which was 66.7%.Viburnum macrocephalum‘Taishan’ had two types of floral organs:most were sterile and only a part was fertile .Stamen abortion and pistil dysgenesis may be the main factors resulting in infertility of Vibur-num macrocephalum.The morphological indicators of F 1 were between those of female and male parents , which indicated F1 be obtained from the hybridization between ‘Taishan’ and ‘Dina’.
