高产大果抗寒日本栗新品种‘黄丰’选育研究

Study on breeding of a new high-yield,large-fruit and cold-resistant Japanese chestnut variety'Huangfeng'

该研究为了选育出丰产、大果、优质且抗寒的日本栗新品种,通过引种驯化和育种研究,成功培育出高产大果抗寒日本栗新品种‘黄丰’。该品种产量稳定,嫁接10 a以上平均产量高达6255 kg·hm^(-2),且果实硕大,平均单果质量达27.17 g,加工品质上乘。在抗寒性方面,‘黄丰’能够抵御-30℃的极端低温,并具备抗栗瘿蜂的能力。该品种在辽宁省丹东、大连等日本栗适宜栽培区具有广阔的种植前景。

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 highyield,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 Liaoning Province.
