Characteristics and Cultivation Technology of High Light Efficiency Rice(Oryza sativa Geng Group)New Variety Longdao 207
摘要
Abstract
In order to promote the promotion of new high-yield rice(Oryza sativa Geng Group)varieties,this article briefly introduced the source,variety characteristics,yield,and cultivation technology of the new high-yield rice(Oryza sativa Geng Group)variety Longdao 207.Longdao 207 is a new high-yield rice(Oryza sativa Geng Group)variety developed by the Institute of Grop Cultivation and Tillage of Heilongjiang Academy of Agricultural Sciences,using the pedigree method of the female parent Ha 1031 and the male parent Dongnong 428.The average yield of regional trials in 2021-2022 was 8 534.7 kg·ha-1,an increase of 8.3％compared to the control variety Longdao 18;The average yield of production trials in 2022 was 8 364.5 kg·ha-1,an increase of 8.7％compared to the control variety Longdao 18.In 2023,Longdao 207 obtained the application number for plant variety rights(20231003593);Approved by Heilongjiang Province in 2023(Heishendao 20230013).This variety has a growth period of about 142 days and requires an accumulated temperature of at least 10 ℃,which is around 2 700 ℃.Through the detection of Fv/Fm values,Longdao 207 can quickly achieve light recovery under high light stress in the field,and can recover from a light inhibition value of 0.283 to 0.740.This variety can maintain high photosynthetic capacity in the field.关键词
