摘要:
福恢673是福建省农业科学院水稻研究所利用明恢86空间搭载后的SP1植株与台农67杂交,F2选株与恢复系N175杂交选育而成的恢复系,具有恢复力强、恢复谱广、配合力好等特点。用福恢673配组的杂交水稻宜优673、Ⅱ优673、川优673、天优673、广优673、粤两优673等系列品种在省级以上区试中表现突出,其中宜优673、Ⅱ优673、川优673、天优673等4个品种共8次通过省级以上审定。本文介绍了恢复系福恢673选育过程、主要生物学特性及配制杂交水稻新品种表现。
Abstract:
Fuhui 673 is a hybrid rice restorer line bred at the Rice Research Institute of Fujian Academy of Agricultural Sciences by crossbreeding the restore line N175 and the F2 plant of crossing between the SP1 plant of Minghui 86 of space mutation and Tainong 67. The resultant hybrid had a strong restoring ability, wide restorer profile and good combining capacity. The series of breeds, including Yiyou 673, II you 673, Chuanyou 673, Tianyou 673, Guangyou 673, Yueliangyou 673, etc., exhibited excellent characteristics in regional trials in and outside the province. Among them, Yiyou 673, II you 673, Chuanyou 673 and Tianyou 673 had passed tests 8 times by the crop variety approval committee beyond the provincial level. The breeding process of the restorer line Fuhui 673, as well as the biological characteristics and performance of these new hybrid rice varieties, is presented.
