摘要
为促进水稻新品种龙稻210的推广应用,本文简要介绍了龙稻210的选育过程、产量表现、特征特性及其配套栽培技术。龙稻210是以东农423为母本、龙稻21为父本,系谱法选育而成,适宜在黑龙江省第一积温带种植的新品种。2020年,龙稻210获得植物新品种保护权,公告号CNA034129E;2021年通过黑龙江省农作物品种审定委员会审定,审定编号为黑审稻20210009。区域试验平均产量为8 046.0 kg·hm^(-2),比对照品种龙稻18增产7.4%;生产试验平均产量为8 328.1 kg·hm^(-2),比对照品种龙稻18增产7.5%。该品种适宜在黑龙江省≥10 ℃活动积温2 700 ℃区域种植。
In order to promote the popularization and application of a new rice variety Longdao 210,the breeding method,breeding process,yield performance,characteristics and supporting cultivation techniques of Longdao 210 were briefly introduced in this paper.Longdao 210 was a nwe variety bred by pedigree method with Dongnong 423 as female parent and Longdao 21 as male parent.It was suitable for planting in the first accumulation zone of Heilongjiang Province by genealogy method.In 2020,Longdao 210 obtained the protection right of new plant varieties,announcement number CNA034129E.On June 11,2021,Longdao 210 was approved by Heilongjiang Provincial Crop Varieties Examination Committee with the number of Heisheng Rice 20210009.In the regional experiment,the average yield of Longdao 210 was 8 046.0 kg·ha^(-1),which increased by 7.4% compared with the control variety Longdao 18.The average yield of Longdao 210 in production test was 8 328.1 kg·ha^(-1),7.5% higher than that of the control variety Longdao 18.This variety is suitable for planting in the area of active accumulated temperature ≥10 ℃ and 2 700 ℃ in Heilongjiang Province.
