- 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合1的选育过程、特征与特性、产量表现，及其栽培技术。龙合1是黑龙江省农业科学院耕作栽培研究所和中国科学院植物研究所合作选育，以母本九稻63、父本龙稻21经系谱方法选育而成的高光效粳稻新品种。2020－2021年区域试验平均产量8 454.6 kg·hm-2，较对照品种增产5.4%；2021年生产试验平均产量8 702.0 kg·hm-2，较对照品种松粳16增产6.2%。2021年9月1日，龙合1获得植物品种权申请号为20211005676；2022年6月20日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20220004。该品种生育日数146 d左右，需≥10 ℃活动积温2 800 ℃左右。
- Abstract:
- In order to promote the popularization of a new japonica rice variety with high photosynthetic efficiency， this paper briefly introduced the breeding process， characteristics， yield performance， and cultivation technology of the new japonica rice variety Longhe 1 with high photosynthetic efficiency. Longhe 1 is a new japonica rice variety with high photosynthetic efficiency， which was jointly bred by the Institute of Grop Tillage and Cultivation of Heilongjiang Academy of Agricultural Sciences and the Institute of Botany of Chinese Academy of Sciences by using the pedigree method of female parent Jiudao 63 and male parent Longdao 21. From 2020 to 2021， the average yield of the regional test was 8 454.6 kg· ha-1， which was 5.4% higher than that of the control variety; In 2021， the average yield of production test will be 8 702.0 kg· ha-1， 6.2% higher than that of the control variety Songgeng 16. On September 1， 2021， Longhe 1 obtained the plant variety right application number (20211005676); It was approved by Heilongjiang Crop Variety Approval Committee on June 20， 2022. The approval number is Heishendao 20220004. The number of growing days of this variety is about 146 days， and the active accumulated temperature of ≥10 ℃ is about 2 800 ℃.
