摘要
为了丰富高产稳产小麦新品种资源,促进河南小麦生产,2011年,河南科技大学利用系统育种法在洛阳种植的淮麦18群体中选育出科大111,并于2021年通过河南省主要农作物品种审定委员会审定。该品种属于半冬性小麦,冬季抗寒性较强,株型松散适度,茎秆弹性好,抗倒性好,对条锈病抗性表现稳定。2017—2018年和2018—2019年度参加河南省区域试验平均产量为6498.0~8518.5 kg/hm^(2),比对照品种周麦18增产2.9%~5.1%,增产试验点比例为63.6%~81.8%。2019—2020年度生产试验平均产量为8128.5 kg/hm^(2),比对照增产4.0%,增产试验点比例为100%。介绍了科大111的选育过程、主要生物学特性、抗性鉴定与品质检测结果以及主要栽培措施。
In order to enrich the resources of new wheat varieties with high and stable yield and promote wheat production in Henan,a new wheat variety Keda 111 was bred by Henan University of Science and Technology through systematic breeding methods from Huaimai 18 populations planted in Luoyang in 2011,which was approved by Henan Province Major Crop Variety Approval Committee.Keda 111 belongs to semi-winter wheat with strong cold resistance,moderate loose plant type,good stem elasticity,good lodging resistance and stable resistance to stripe rust rust.The average yield of Kada 111 in Henan regional trials in 2017 and 2018 was 6498.0-8518.5 kg/hm^(2),which was 2.9%-5.1%higher than that of the control variety Zhoumai 18(CK),and the average ratio of test sites with increased output was 63.6%-81.8%.The average yield of Kada 111 in production test in 2019—2020 was 8128.5 kg/hm^(2) which was 4.0%higher than that of CK,and all the experimental sites showed an increase in output.The selection and breeding process,main biological characteristics,results of resistance identification and quality testing and suitable cultivation measures of Keda 111 were introduced in this paper.
