Study on breeding of a new high-yield,large-fruit and cold-resistant Japanese chestnut variety'Huangfeng'
This study aimed to select and breed new varieties of Japanese chestnut with high yield,large fruit,good quality and cold resistance.Through introduction,domestication and breeding research,a new variety of high-yield,large-fruit and cold-resistant Japanese chestnut'Huangfeng'was successfully bred.This variety had stable yield,with an average yield of 6255 kg·hm-2 over 10 years of grafting.At the same time,its fruits were large,with an average single fruit weight of 27.17 g,and excellent processing quality.In terms of cold resistance,'Huangfeng'can resist extreme low temperatures of-30 ℃ and had resistance to chestnut gall wasp.Therefore,this variety has broad planting prospects in suitable cultivation areas of Japanese chestnut in Dandong,Dalian and other places in Li-aoning Province.
