对粳型广亲和系０２４２８与籼型广亲和系培矮６４的杂种Ｆ１进行花培，在８０余份花培系中选出一综合性状优良的株系作为轮回亲本，通过连续回交对野败型质核互作不育系珍汕９７Ａ作核置换，育成了野败型广亲和不育系０６４Ａ。０６４Ａ育性稳定，开花习性好，广亲和性强，配合力高。其中与粳型恢复系９５１２组配的Ｆ１穗大粒多，结实率高，优势非常明显，具有进一步开发利用的潜力。
The hybrid F1 of japonica-wide compatibility line 02428 and indica-wide compatibility line Pei-dao 64 was cultivated, and the line with excellent comprehensive characters was selected as the recurrent parent in more than 80 flower-cultivated lines. The wild-type nuclear-sterility male sterile line Zhenshan 97A was used as a nucleus replacement, and a wild-type broad-compatible male sterile line 064A was bred. 064A Fertility stability, good flowering habits, wide compatibility, high combining ability. Among them, F1 spike large grain with 9512 group of japonica restorer, with high seed setting rate and obvious advantage, has the potential for further development and utilization.
