摘　　要：惠A是广西桂穗种业有限公司采用复合杂交方法育成惠B（金23B∥广选3号/05占）后再与金23A测交和回交转育而成的早籼型感温不育系。惠A株型紧凑;生育期较短,播始历期比金23A长2～3 d;不育性稳定,不育株率100%,花粉不育度99.98%;异交习性好,柱头外露率达82.9%;可恢复性好,配合力较强;稻米品质较优,抗逆性较强。2005年3月通过广西区品种审定。Hui A, developed by the Guisui Seed Industry Co. Ltd. through testcrossing Huizhan, derived from the multiple crosses of Jin 23B//Guangxuan 3/05 Zhan, to Jin 23A and adopting the successive backcrossing method, is a new early indica CMS line in rice.

Its male sterility is stable and complete （pollen sterility at 99.98% and sterile plant rate at 100% ）. It has good habits with its stigma exsertion rate as high as 82.9%, ances. In March, 2005, it was certified by the Guangxi restorability, high combining ability, favorable flowering comparatively good grain quality and strong stress resist- Crop Variety Appraisal Committee.
