- 摘要:
- 为促进黑龙江省第一积温带香稻新品种的选育及推广，本文介绍了香型粳稻新品种龙稻204的选育过程、品种特性、产量表现及栽培技术。龙稻204是黑龙江省农业科学院耕作栽培研究所以哈9230为母本、五优稻4号为父本，采用系谱法选育而成的香稻新品种，在多年鉴定试验中表现出丰产性优良、品质好及耐冷性强等特性。2021－2022年区域试验平均产量为8 035.5 kg·hm-2，较同区域对照品种松粳22增产7.6%；2022年生产试验平均产量为8 051.5 kg·hm-2，较同区域对照品种松粳22增产8.1%。2023年龙稻204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20230006。该品种在适应区域从出苗到成熟生育日数146 d左右，适宜在黑龙江省第一积温带上限区域种植。
- Abstract:
- In order to promote the breeding and promotion of the first fragrant rice variety in Heilongjiang Province, this article introduces the breeding process, variety characteristics, yield performance, and cultivation techniques of the fragrant rice (Oryze sative Geng Group) variety Longdao 204. Longdao 204 was a new fragrant rice variety seleced by Institute of Corp Cultivation and Tillage of the Heilongjiang Academy of Agricultural Sciences, with Ha 9230 as the female parent and Wuyou Rice 4 as the male parent. It had shown excellent yield, good quality, and strong cold tolerance in identification experiments for many years. The average yield of regional trials from 2021 to 2022 was 8 035.5 kg·ha－1, which increased by 7.6% compared to the control variety Songjing 22 in the same region; In 2022, the average production trial yield was 8 051.5 kg·ha－1, which increased by 8.1% compared to the control variety Songjing 22 in the same region. In 2023, Longdao 204 was approved by the Heilongjiang Provincial Grop Variety Approval Committee with the approval number Heishendao 20230006. This variety has a growth period of about 146 days from emergence to maturity in the adaptation area, making it suitable for planting in the upper limit area of the first accumulated temperature zone in Heilongjiang Province.
