To comprehensively understand the flowering,pollination and fruiting characteristics of peony in Zhongyuan area,and to analyze its breeding and utilization value,providing a reference for the cultivation of new varieties of peonies.In this experiment,11 peony varieties from Zhongyuan area,including'Manyuanchunguang','Hongbanbai'and'Tingtingyuli',were selected as test materials.The fruiting conditions were investigated using various methods such as self-crossing,hybridization,and open pollination.The results showed that self-crossing of varieties in Zhongyuan area had a small amount of fruiting,and the fruit-setting percentage of cross-flowering was higher than self-flowering,the setting percentage of self pollination during selfing were 0.31 grain/flower,and the setting percentage of cross pollination of selfing were 0.76 grain/flower.Under different pollination methods,the setting percentage(9.4 grain/flower)and the fruit setting rate(90%)of artificial hybridization were higher than that of open pollination and self-crossing,the average dry weight of seeds were 0.31～0.36 g/grain,and the largest dry weight of seeds(0.5875g/grain)of the hybrid combination was'Caiju×Hudiefeiwu'.It is concluded that cross-pollination is the main method of pollination for peonies in Zhongyuan area,and arti-ficial directional hybridization can effectively improve the setting percentage.
