纤维用与造纸兼用的高产型红麻H2101的选育
Breeding of High-yield Kenaf H2101 for Both Fiber and Papermaking
摘要
Abstract
This study successfully bred a new combination of fiber and papermaking dual-use kenaf,Zhongzahong 2101(H2101),which combines high yield,disease resistance,high quality,and wide a-daptability through germplasm resource innovation and hybrid vigor model optimization.In 2016,with Zhonghongma No.17 as the father line,K1703A was used as the maternal parent to construct a hybrid combination.Through multiple generations of targeted breeding,a genetically stable superior hybrid was obtained.In the 2019-2020 strain comparison experiment,its F1 and F2 generations showed outstanding yield performance,recorded as super hybrid kenaf.In the comparative experiment between Yuanjiang and Changsha from 2020 to 2021,the fiber yield of the experimental group reached 6 100-6 200 kg/hm2,which increased by 17.39%and 19.70%compared to the control group.The dry stem yield increased sig-nificantly by 22 000-23 000 kg/hm2,the fiber count reached 269 m/g,and and the strength was 421 N.On December 28,2023,it was evaluated and approved by the expert group of the Anhui Province Non Major Crop Variety Identification and Registration Committee,the kenaf H2101 Jiandeng Zi 2209021 is a new combination of high yield,disease resistance,high quality,and wide adaptability,which combines strong advantages and high yield for fiber and paper production.It solves the problem of coordinated opti-mization of raw material supply in the hemp and paper industries and provides high-quality seed source support for the diversified utilization of kenaf.关键词
