Breeding and Cultivation Technology of A New Rice Variety Kendao 1866

为促进水稻新品种垦稻1866的推广应用,本文简要介绍了垦稻1866的选育过程、品种特征特性及配套栽培技术。垦稻1866是黑龙江省农垦科学院水稻研究所以空育131为母本,龙粳31为父本配制杂交组合,通过系谱法选育出的水稻新品种,2020年通过黑龙江省农作物品种审定委员会审定(审定编号:黑审稻2021L0107)。该品种在适应区出苗至成熟生育日数127 d左右,需≥10℃活动积温2300℃左右。在黑龙江省属早熟型品种,适合黑龙江省第三积温带种植。在多年生产鉴定中表现出丰产性好,穗粒结构合理,株叶收敛,后期灌浆速度快,活秆成熟不早衰等特性。

In order to promote the popularization and application of a new rice variety Kendao 1866,this paper briefly introduced the breeding process,variety characteristics and supporting cultivation technology of Kendao 1866.Kendao 1866 is a new rice variety developed by the hybrid combination of Kongyu 131 and Longjing 31 from the Rice Research Institute of Heilongjiang Academy of Agriculture and Reclamation Sciences.The new rice variety was bred through the pedigree method and passed the crop variety certification of Heilongjiang Province in 2020(Approval number:Heishendao 2021L0107).The number of days from emergence to maturity of this variety in the adapted area is about 127 days,and the active accumulated temperature of≥10℃is about 2300℃.It is an early-maturing variety in Heilongjiang Province,suitable for planting in the third accumulative temperate zone of Heilongjiang Province.In the production appraisal for many years,it showed good yield,reasonable ear-grain structure,convergence of plant and leaf,fast filling rate in later stage,and non-premature aging of live stalks.
