摘要：

嘉禾3686A是嘉兴市农业科学研究院以高配合力、圆粒型粳稻新品系嘉禾3686B为父本，以BT型不育源供体151A为母本，杂交后经多代回交转育而成的BT型迟熟晚粳三系不育系，具有株型紧凑、分蘖力强、圆粒、制繁种性状好等特点，2025年12月通过浙江省农作物品种审定委员会鉴定。利用该不育系配组育成的组合嘉禾优726（嘉禾3686A×G7263）于2021年通过国家农作物品种审定委员会审定。

Abstract:

Jiahe 3686A is a BT-type late-maturing late-season japonica three-line CMS line developed by the Jiaxing Academy of Agricultural Sciences. It was bred by using the high combining ability round-grain japonica line Jiahe 3686B as the male parent and the BT-type CMS donor 151A as the female parent，followed by multiple generations of backcrossing. This line exhibits a compact plant type，strong tillering ability，round grains，and favorable traits for seed production and propagation. The line was certified by the Zhejiang Provincial Crop Variety Approval Committee in December 2025. The hybrid combination Jiaheyou 726（Jiahe 3686A × G7263），developed using this CMS line，was approved by the National Crop Variety Approval Committee in 2021.

Key words: rice, japonica CMS line, Jiahe 3686A, round grain, breeding
