人物简介

从鹤壁一株叶形变异单株育成杜仲新品种'华仲23号'。

事迹

杜庆鑫，中国林业科学研究院经济林研究所经济林种质创新与利用国家林业和草原局重点实验室科研骨干（南京林业大学联合培养博士），是杜仲育种团队青年一代的代表人物。2007年他在杜仲资源调查中于河南省鹤壁市发现一株叶形奇特的变异单株，经连续嫁接繁殖观察、无性系测定和区域试验，育成新品种'华仲23号'，2018年通过河南省林木良种审定，2021年获国家植物新品种权证书。

他作为第一选育人培育的'华仲20号'杜仲为晚花油用良种，比普通杜仲开花期晚7-10天，可避开晚霜危害，种仁粗脂肪含量达36%-42%、亚麻酸含量59%-64%，盛果期年产果量170-230kg/亩，为杜仲籽油（α-亚麻酸）产业提供了专用良种，体现了我国杜仲育种向油料化、功能化定向培育的最新进展。

重要活动 / 事件

2024年在《南京林业大学学报》发表'华仲23号'杜仲新品种选育报告
2020-2022年'华仲20号''华仲21号'相继通过国家林草局审定和植物新品种权授权
长期在河南原阳、孟州等中国林科院经济林所试验基地开展杜仲无性系测定与区域试验

代表贡献

2007年在河南鹤壁发现叶形奇特杜仲变异单株，历经10余年选育成'华仲23号'，2018年通过河南省良种审定，2021年获国家植物新品种权
作为第一选育人培育油料用杜仲良种'华仲20号'（国S-SV-EU-012-2020），种仁粗脂肪含量36%-42%
参与选育'华仲16号''华仲21号''华仲26号'等多个杜仲良种和新品种

Profile

Bred the new Eucommia cultivar 'Huazhong 23' from a leaf-shape variant individual found in Hebi.

Story

Du Qingxin is a key researcher at the Key Laboratory of Non-timber Forest Germplasm Innovation and Utilization of the National Forestry and Grassland Administration, Research Institute of Non-timber Forestry, Chinese Academy of Forestry (PhD jointly trained with Nanjing Forestry University), and a representative of the younger generation of the Eucommia breeding team. In 2007, during a Eucommia resource survey, he discovered a variant individual with unusual leaf shape in Hebi, Henan. Through successive graft propagation and observation, clonal testing and regional trials, he developed the new cultivar 'Huazhong 23', which passed Henan provincial improved-variety certification in 2018 and received a national plant variety rights certificate in 2021.

The Eucommia variety 'Huazhong 20', which he bred as first breeder, is a late-flowering oil-use variety that flowers 7-10 days later than common Eucommia, escaping late-frost damage. Its kernels contain 36%-42% crude fat and 59%-64% linolenic acid, with an annual fruit yield of 170-230 kg per mu at full bearing, providing a dedicated variety for the Eucommia seed oil (alpha-linolenic acid) industry and exemplifying the latest progress in China's directed breeding of Eucommia toward oil and functional uses.

Milestones

In 2024, published the breeding report of the new Eucommia cultivar 'Huazhong 23' in the Journal of Nanjing Forestry University
From 2020 to 2022, 'Huazhong 20' and 'Huazhong 21' successively passed certification by the National Forestry and Grassland Administration and were granted plant variety rights
Has long conducted Eucommia clonal testing and regional trials at the experimental bases of the Research Institute of Non-timber Forestry in Yuanyang and Mengzhou, Henan

Key Contributions

In 2007, discovered a Eucommia variant individual with unusual leaf shape in Hebi, Henan; after more than 10 years of selection it became 'Huazhong 23', certified by Henan Province in 2018 and granted national plant variety rights in 2021
As first breeder, developed the oil-use improved Eucommia variety 'Huazhong 20' (national registration S-SV-EU-012-2020), with kernel crude fat content of 36%-42%
Participated in breeding multiple improved Eucommia varieties and new cultivars including 'Huazhong 16', 'Huazhong 21' and 'Huazhong 26'
