Breeding and Cultivation Technology of A New Rice Variety Nongfeng 1702 in Cold Region

为促进水稻新品种农丰1702的推广应用,本文介绍了其选育过程、特征特性、产量表现及栽培技术。水稻新品种农丰1702是黑龙江八一农垦大学水稻研究中心以五优稻4号为母本、龙粳21为父本杂交,经系谱法选育而成,于2017-2018年参加黑龙江省常规优质稻组区域试验,平均产量为8899.90 kg·hm-2,较对照增产3.70%;2019年参加黑龙江省常规优质稻组生产试验,平均产量为8768.70 kg·hm-2,较对照增产6.30%。2020年5月通过黑龙江省农作物品种审定委员会审定(黑垦审稻20200004),该品种具有高产、抗倒性强、耐冷性强、株型收敛、适应性广等优点,适宜在黑龙江省≥10℃活动积温2600℃的地区种植。

In order to promote the popularization and application of A new rice variety Nongfeng 1702,this paper introduced its breeding process,characteristics,yield performance and cultivation technology.Nongfeng 1702,a new rice variety,was bred by crossing Wuyoudao No.4 as female parent and Longjing 21 as male parent by the Rice Research Center of Heilongjiang Bayi Agricultural Reclamation University,and it was selected by pedigree method and participated in the regional test of conventional high-quality rice group in Heilongjiang Province from 2017 to 2018.The average yield was 8899.90 kg·hm-2,increased by 3.70%compared with the control;In 2019,the average yield of conventional high-quality rice group in Heilongjiang Province was 8768.70 kg·hm-2,which was 6.30%higher than the control.In May 2020,it was approved by Heilongjiang Provincial Crop Variety Approval Committee(Heikenshendao 20200004).It has the advantages of high yield,strong lodging resistance,strong cold tolerance,plant type convergence,wide adaptability and so on,and it is suitable for planting in the area with≥10℃active accumulated temperature of 2600℃in Heilongjiang Province.
