摘　　要：将０２４２８／Ｔ９８４//Ｔ１９５０杂种后代进行花药培养获得纯合的二倍体花粉植株，分别与珍汕９７Ａ、Ｖ２０Ａ和７６２７Ａ杂交，分析其恢复能力。有８份花培系Ｆ１结实率均在６５％以上，且有较强的杂种优势，可作为广亲和恢复系的种质，证实花培是选育水稻广亲和恢复系的快速有效途径。Fifteen doubled haploid rice lines derived from 02428/T984 T1950 by anther culture weretestcrossed with Zhenshan 97A, V20A(indica) and 7627A(japonica). When the doubled haploid lines weretestcrossed with Zhenshan 97A, V20A and 7627A the seed setting percentages of their F1 hybrids averaged at83.36%(71.3%～87.7%), 73.51%(66.8%～81.8%)and 83.69%(65.8%～95.2%), respectively. Ofthem some lines showed very strong F1 heterosis and could be used as germplasms in the breeding of intersub-specific hybrid rice, Therefore, anther culture is a useful method in developing wide-compatibility restorerlines in hybrid rice.
