摘要:
为促进香稻新品种的推广及应用，本文简要介绍了香稻新品种龙稻203的选育过程、特征特性、产量表现及配套栽培技术。龙稻203是以五优稻4号为母本，绥粳4号为父本，采用系谱法选育而成的香稻新品种，于2020年7月15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20200053。2019年，龙稻203获得植物新品种保护权，申请号20191006401；2020年，获得植物新品种保护公告号CNA030964E。区域试验平均产量8 000.7 kg·hm-2，较对照品种增产6.7%；生产试验平均产量7 780.7 kg·hm-2，较对照品种增产8.0%。该品种在适应区域从出苗到成熟生育日数140 d左右，需≥10 ℃活动积温2 700 ℃左右。在多年的生产鉴定试验中表现出较好的丰产性、优良的米质及抗倒伏等特性。
Abstract:
In order to promote the popularization and application of new fragrant rice variety, this paper briefly introduced the breeding process, characteristics, yield performance and supporting cultivation technology of new fragrant rice variety Longdao 203. Longdao 203 is a new fragrant rice variety bred by using pedigree method with female parent Wuyou rice 4 and male parent Suigeng 4. It was approved by Heilongjiang Crop Variety Approval Committee on July 15th, 2020, and the variety approval number is Heishendao 20200053.Longdao 203 obtained the application number for the protection right of new plant varieties (20191006401) in 2019 and the announcement number for the protection of new plant varieties in 2020 is CNA030964E.The average yield of regional test was 8 000.7 kg·ha-1, which was 6.7% higher than that of the control variety; The average yield of production test was 7 780.7 kg·ha-1,which was 8.0% higher than that of the control variety.In the adaptive area, the number of growth days from emergence to maturity is about 140 days, and the active accumulated temperature ≥10 ℃ is about 2 700 ℃.In many years of production appraisal tests, it has shown good high yield, high rice quality, lodging resistance and other characteristics.
