摘　　要："金优458"是用优质不育系"金23A"与江西省农科院水稻所育成的早稻强恢复系"R458"配组而成的高产早籼迟熟组合。该组合株叶形态好,分蘖力强,结实率高,千粒重大,制种产量高,适宜在长江流域中下游地区作迟熟早稻种植。介绍了"金优458"的特征特性和高产制种技术要点。A new high-yielding late-maturing early indica rice combination 'Jinyou 458' was bred by crossing between good quality male sterile line 'Jin 23A' and strong restoring line 'R458' bred by Rice Research Institute, Jiangxi Academy of Agricultural Sciences. 'Jinyou 458' is characterized by ideal plant type, strong tillering ability, high setting rate, heavy 1000-grain weight, and high seed productive yield. It is suitable for 'Jinyou 458' to be planted as late-maturing early rice in the mid-lower branches of the Changjiang River. In addition, the characters and high-yielding seed production techniques of 'Jinyou 458' were introduced in this paper.
