摘　　要：近年来全国水稻审定品种数量爆发式增长,江苏省审定的水稻品种数也急剧增加。本研究收集了2020—2024年江苏省审定的所有水稻品种农艺性状数据,按照籼粳亚种和试验渠道进行了分类,比较分析了不同试验渠道的水稻审定品种农艺性状差异和年度变化趋势。2020—2024年江苏省审定的水稻品种达到400个,其中籼稻73个,粳稻327个;参加省区试的品种109个,联合体试验228个,自主试验60个,绿色通道3个,不同试验渠道审定的水稻品种部分农艺性状存在显著差异。本研究将有助于育种家优化育种策略,使选育的品种更加适应市场需求。In recent years,the number of rice varieties approved in China has exploded,and the number of rice varieties approved in Jiangsu Province has also increased dramatically.In this study,the agronomic traits data of all rice varieties approved in Jiangsu Province from 2020 to 2024 were collected and classified according to indica-japonica subspecies and test channels.The differences in agronomic traits and annual trends of rice varieties approved in different test channels were compared and analyzed.From 2020 to 2024,there were 400 rice varieties approved in Jiangsu Province,including 73 indica rice and 327 japonica rice.There were 109 varieties participating in the provincial regional test,228 in the combination test,60 in the independent test,and 3 in the green channel.There were significant differences in some agronomic traits of rice varieties approved through different test channels.This study will help breeders to optimize breeding strategies and make the selected varieties more suitable for market demand.
