Abstract

In order to improve the yield and quality of new varieties Castanea mollissima cv. “Zipo”, Castanea mollissima cv. “Zunyu” and traditional Yan Mountain cultivars Castanea mollissima cv. “Duanci”, Castanea mollissima cv. “Yanhong”, Castanea mollissima cv. “Donglingmingzhu”, an experiment was carried out to study varieties combination that was suitable for their pollination. Fruiting rate and seed-setting rate were used to decide which the most suitable configuration was. The result indicated that: Castanea mollissima cv. “Zunyu” was the best pollination tree for Castanea mollissima cv. “Yanhong”, Castanea mollissima cv. “Zipo” and Castanea mollissima cv. “Duanci”; Castanea mollissima cv. “Duanci” was regarded as the best pollination tree for Castanea mollissima cv. “Zunyu”; the best variety to comply with Castanea mollissima cv. “Donglingmingzhu” was Castanea mollissima “Zunyu” and Castanea mollissima cv. “Duanci”; Castanea mollissima cv. “Zunyu” and Castanea mollissima cv. “Duanci” complied with each other best. Appropriate configuration of pollination varieties turned out to be one of the key measures to improve the yield and quality of chestnut, while irrational combination may even bring the reduction of output.
