摘要
在应用花培技术选育出广亲和恢复系种质ＴＧ７的基础上，为克服其与籼型不育系杂交生育期严重超亲的缺点，以ＴＧ７作为亲本与明恢６３等优良恢复系进一步杂交和复交，并结合花药培养初筛到ＹＱ１、ＹＱ２、ＹＱ３、ＹＱ４、ＹＱ５等５个优良花培系，分别与协青早Ａ、Ｉ－３２Ａ、７６２７Ａ、秋光Ａ、新光Ｓ、ＨＰ１３Ｓ等雄性不育系测交表现广亲和恢复性，部分还表现较强的杂种优势，可以在生产上试种．
The widely compatibility restorer (WCR) line TG7 derived early was used as a parent, five new WCR lines YQ1, YQ2, YQ3, YQ4 and YQ5 were developed by anther culture. The new WCR lines showed not only good widely compatibility and restorability to different indica and japonica male sterile lines, but also with strong heterosis.
