摘要
1987-2022年吉林省共审定水稻品种721个,本研究分析了审定品种的数量、来源、亲本引用情况和农艺性状等。结果表明,审定水稻品种数量逐年上升,其中在2000年和2017年增加幅度较大;科研院所和高校是选育主体;亲本来源相对集中,其中日系亲本血缘占比较高;通过品种改良实现了水稻产量的显著提升;中晚熟和晚熟型品种是吉林省水稻品种选育的核心;2001年之后株高、穗长及穗粒数开始显著上升同时千粒重开始下降。对吉林省水稻品种选育的历史进行了总结和归纳,对影响品种数量、品种类型、亲本选择和品种性状的因素进行了分析,对未来育种目标进行了讨论。
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.
