Abstract
In order to promote the application of new glutinous rice variety Longgeng 1823 and the development of glutinous rice industry in Heilongjiang,this paper introduced the source of parents,breeding process,characteristics,yield performance and key points of cultivation technology of Longgeng 1823.Longgeng 1823,a new glutinous rice variety with good quality,was developed by the Institute of Rice Research,Heilongjiang Academy of Agricultural Sciences,using self-bred parent material Longjiao 11-4474 as female parent and Longjiao 11-4055 as male parent.From 2019 to 2020,Longgeng 1823 participated in the regional trials of the glutinous rice group under the lower limit of the second temperature zone in Heilongjiang Province,the average yield was 8 228.7 kg·ha-1,which was 8.5％higher than Longnuo 3;And Longgeng 1823 participated in production trials in 2021,the average yield was 8 992.9 kg·ha-1,which was 8.3％higher than Longnuo 3.The three-year trial yields were all more than 8.0％higher than the reference variety Longnuo 3,which was belongs to the high-yielding type.Approved by Heilongjiang Crop Variety Approval Committee in 2022(Approval number:Heishendao 20220064).After analysis and identification in 2020-2021,the quality of Longgeng 1823 rice reached the national standard of glutinous rice.It has the characteristics of excellent rice quality,ideal plant type,high yield,and good comprehensive resistance.
