Abstract

In order to improve the yield and quality of 5 new Castanea mollissima varieties “Zipo”, “Zunyu” and traditional Yan Mountain Castanea mollissima cultivars “Duanci”, “Yanhong” and “Donglingmingzhu”, we carried out an experiment to study effect from different varieties configuration on yield of Yan Mountain chestnut. The result indicated that: cross-pollination had a significant impact on both fruiting rate and seed-setting rate; cross-pollination improved the nut number in each burr of each variety, in which “Duanci” was the biggest beneficiary, whose number of nut per burr increased from 1.08 to 2.77, 156% higher than that of the self-pollination combination; nut weight showed no significant difference in Xenia Effection; “Zunyu” improved the yield of “Yanhong” most; “Donglingmingzhu” was regarded as the best tree to improve “Zunyu”’s yield; the best variety to improve yield of “Zipo” was “Zunyu”; “Donglingmingzhu” and “Duanci” improved yield of each other most.
