( 2 ) under spring sowing environment, sterility could be selected, but not maintained. thereby, lines selected could only be selected as recorded selection method in the experiment. ( 3 ) and then, selection was carried out from spring sowing line selected into summer sowing in same line with tps to select plants. these plants through the intercrossing selection had been combined with sterility and tps. in this way, a new selection protocol for selection sterile line with tps was formed. it mainly involves the spring and summer sowing method, recorded selection method and the intercrossing selection method

    為了育新類型玉米雄性核不育系,提出了為玉米核不育性添加溫光敏感性的設想和與鑒定相結合的策略,同時應用分期播種的方法為作物提供不同的生長和發育的環境條件,以鑒定玉米雄穗的育性變化和對不同環境條件溫光的反應.研究結果表明,春播環境下可鑒定和玉米的不育性,夏播環境下可鑒定和其溫光敏感性.針對玉米核不育性難以找到保持系的特性,結合兩種播期兩種性狀.但春播環境下的不育性難以通過單株來保持其不育性,為記錄性群體選擇.通過從春播入的雜合不育性優良株系轉移到其對應的夏播溫光敏感性入的同一優良中進行優良單株,能逐漸使不育性和溫光敏感性相結合而育出純合溫光敏不育系.這種新的程序主要包括應用分期播種法、記錄性法和春夏兩季交叉式法,使含有不育基因的可育株系逐步累積不育基因並增加了溫光敏感性而育成玉米溫光敏不育系
