我国野败型三系虽已在生产上大面积利用,但仍有些问题需要研究解决。选育不同于野败质源的新三系,是解决野败型三系一些难题的有效办法。我们选育的意广三系,F1表现早熟,优势明显;不育系恢复谱广,异交结实率高,不育性能稳定。如意广A×方早28,小面积优势鉴定,比对照湘矮早9号增
Although China’s wild-type three-line system has been used extensively in production, some problems still need to be solved. Breeding different from the source of the new three lines of wild cats is an effective solution to some of the problems of wild-type three lines. We selected three lines of broad sense, F1 performance precocious, obvious advantages; broad spectrum sterile line recovery, seed setting rate, sterility stable. Aspire A × square as early as 28, identification of small area advantages, compared with the control Xiang shortened as early as 9 increase
