摘　　要：为促进高光效粳稻新品种的推广,本文简要介绍高光效粳稻新品种龙稻207的选育过程、品种特性、产量及其栽培技术要点。龙稻207是黑龙江省农业科学院耕作栽培研究所选育,以母本哈1031、父本东农428采用系谱法选育而成的高光效粳稻新品种。2021-2022年区域试验平均产量8534.7 kg·hm^(-2),比对照品种龙稻18增产8.3%;2022年生产试验平均产量为8364.5 kg·hm^(-2),比对照品种龙稻18增产8.7%。2023年,龙稻207获得植物品种权申请号(20231003593);2023年通过黑龙江省审定(审定编号为黑审稻20230013)。该品种生育日数142 d左右,需≥10℃活动积温2700℃左右。通过Fv/Fm值检测龙稻207在大田高光胁迫下能够快速实现光恢复,可以从光抑制值0.283恢复到0.740,该品种能够维持大田下的高光合作用能力。In order to promote the promotion of new high-yield rice(Oryza sativa Geng Group)varieties,this article briefly introduced the source,variety characteristics,yield,and cultivation technology of the new high-yield rice(Oryza sativa Geng Group)variety Longdao 207.Longdao 207 is a new high-yield rice(Oryza sativa Geng Group)variety developed by the Institute of Grop Cultivation and Tillage of Heilongjiang Academy of Agricultural Sciences,using the pedigree method of the female parent Ha 1031 and the male parent Dongnong 428.The average yield of regional trials in 2021-2022 was 8534.7 kg·ha^(-1),an increase of 8.3%compared to the control variety Longdao 18;The average yield of production trials in 2022 was 8364.5 kg·ha^(-1),an increase of 8.7%compared to the control variety Longdao 18.In 2023,Longdao 207 obtained the application number for plant variety rights(20231003593);Approved by Heilongjiang Province in 2023(Heishendao 20230013).This variety has a growth period of about 142 days and requires an accumulated temperature of at least 10℃,which is around 2700℃.Through the detection of Fv/Fm values,Longdao 207 can quickly achieve light recovery under high light stress in the field,and can recover from a light inhibition value of 0.283 to 0.740.This variety can maintain high photosynthetic capacity in the field.
