Data Analysis of Approved Rice Varieties in Jilin Province from 1987 to 2022
摘要
Abstract
In Jilin Province,721 rice varieties were approved from 1987 to 2022.The number of approved varieties,their origins,the parental lines used,and their agronomic traits were all examined in this study.The findings showed that approvals of rice varieties increased annually,among which the increase was relatively large in 2000 and 2017.Breeding efforts were primarily led by research institutes and universities,with a tendency to use a concentrated pool of parental lines,particularly those of Japanese descent.There was a marked improvement in rice yields attributed to variety enhancement.Medium-late and late-maturing varieties constituted the focus of variety selection and breeding in Jilin Province.After 2001,plant height,panicle length,and the number of grains per panicle began to increase significantly,while the 1000-grain weight showed a decreasing trend.The history of rice variety selection and breeding in Jilin Province was comprehensively reviewed,and the factors influencing the number of varieties,variety types,selection of parental lines,and variety traits were analyzed.Prospective breeding objectives were outlined as well.关键词
