摘  要：
以香稻不育系GHS与无香味恢复系和香稻品种杂交,采用咀嚼法测定杂交组合F1米粒和KOH溶液法测定杂交组合F1、F2、BC1F1植株的香味遗传特点。结果表明,恢复系无香味为显性性状,GHS的香味为隐性性状;GHS的香味基因与粤香占、湘晚籼17号的香味基因不等位;GHS的香味基因与玉香油占、天龙香103、新万香、创香5号香味基因可能存有等位位点。与无香味恢复系杂交组合F2植株群体无香味与有香味之比符合3∶1的分离比,BC1F1植株群体符合1∶1的分离比,GHS的香味遗传受1对隐性核基因控制。在杂交水稻育种中,利用GHS系统选育出琼香S,并选配出一批香型杂交稻组合,其中琼香两优1号、琼香两优2号等高产优质组合已通过省级审定,具有较好的应用前景。

摘  要：
The inheritance of aroma of GHS was studied by crossing GHS to non- aromatic lines 9311,Xianhui207,Yuefengzhan,Taihuangzhan,Yuexiangzhan and aromatic lines Yuxiangyouzhan,Xiangwangxian 17,Yuxiangyouzhan,Tianlongxiang,Xinwanxiang,Chuangxiang 5. Based on the performance of aroma tested by chewing method in kernels of F1generation and KOH solution method in plants of the generations of F1,F2,BC1F1,the results show that non- aroma of the restorer is dominant traits,aroma of GHS is recessive traits; recessive aroma gene of GHS,Yuxiangyouzhan,Xiangwangxian 17 were non- allelic,recessive aroma gene of GHS,Yuxiangyouzhan,Tianlongxiang,Xinwanxiang,Chuangxiang 5 may be have same allelic loci. The ratios of non- aromatic to aromatic in plants of the generations of the F2and BC1F1plants which crossing of GHS to non- aromatic lines at 3∶ 1 and 1∶ 1 respectively,the inheritance of aroma of GHS is controlled by a recessive nuclear gene. In hybrid rice breeding,breeding out Qiongxiang S from GHS,a group of hybrid combinations mated with Qiongxiang S show both high yielding ability and good grain quality with aroma,among which Qiongxiangliangyou 1, Qiongxiangliangyou 2 have been registered and released to commercial production,and show a very good prospect.
