摘　　要：粳216A是辽宁省水稻研究选育的粳型三系新不育系,于2020年通过辽宁省农作物品种审定员会鉴定。粳216A不育性稳定、异交结实率高、花时早、配合力好、制种产量高、抗病性强。利用该不育系组配制的杂交稻新组合粳216优34进入辽宁省区试,产量比对照高9.5%。Jing 216 A is a new japonica CMS line bred by Liaoning rice research institute. It was registered and released for commercial use in Liaoning province in 2020. Its characters was stable sterility, high outcrossing seed setting rate, early flowering time, good combining ability, high seed production yield, and strong disease resistance.
