In order to solve the problems of high empty bud rate and poor fruit set in the cultivation of chestnut pollination varieties can be rationally allocated In Chencang district of Baoji city for the main varieties ‘Taishan No 1’ and ‘Qinli No 2’ ‘Hongli’ ‘Xinzao li’ ‘Shifeng’ ‘Sheli’ and two main varieties were selected as pollination varieties and their fruit characteristics fruit traits and quality were measured and analyzed The results show that 1 In addition to ‘Taishan No 1’ and ‘Qinli No 2’ as pollinating species outcrossing significantly improved the seed setting rate and achievement rate of chestnut and reduced the empty bud rate 2 ‘New chestnut’ as the parent significantly reduced the empty bud rate of chestnut and ‘She chestnut’ as the parent significantly increased the fruit yield seed kernel protein and starch content of chestnut and ‘Shifeng’ as the parent significantly increased the soluble sugar content of chestnut kernel and reduced the fat content 3 Based on the analysis of yield fruit traits and principal components three pollination combinations ♀×♂ with high yield and high fruit quality were selected as ‘Qinli No 2’בShili’ ‘Qinli No 2’בShifeng’ and ‘Taishan No 1’בSheli’ Reasonable variety pollination configuration can effectively reduce the empty bud rate of chestnut fruit in Chencang district Baoji city improve the fruit quality and yield and achieve high yield and high-quality cultivation
