棉花洞a雄性核不育系是1972年从洞庭一号棉花原种圃中发现的突变体，不育度高且稳定，可育与不育花粉在单核期以前发育同步，是研究棉花花药与花粉发育相关基因的理想材料。 | | 2. | In order to select male nucleo - sterile new genotype , a tentative idea was put forward for the nucleo - male sterility to attach a tps ( thermo - photoperiod sensitivity ) and a selection strategy of combination of selection and identification , at the same time , the spring and summer sowing method were used to provide different environment conditions of appraising sterility and tps . the results indicated that ( 1 ) sterility could be appraised under the spring sowing environment and tps could be appraised under summer sowing environment . ( 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
为了选育新类型玉米雄性核不育系,提出了为玉米核不育性添加温光敏感性的设想和选择与鉴定相结合的策略,同时应用分期播种的方法为作物提供不同的生长和发育的环境条件,以鉴定玉米雄穗的育性变化和对不同环境条件温光的反应.研究结果表明,春播环境下可鉴定和选择玉米的不育性,夏播环境下可鉴定和选择其温光敏感性.针对玉米核不育性难以找到保持系的特性,结合两种播期选择两种性状.但春播环境下选择的不育性群体难以通过选择单株来保持其不育性,为记录性群体选择.通过从春播入选的杂合不育性优良株系群体转移到其对应的夏播温光敏感性入选的同一优良群体中进行优良单株选择,能逐渐使不育性和温光敏感性相结合而选育出纯合温光敏不育系.这种新的选择程序主要包括应用分期播种法、记录性选择法和春夏两季交叉式选择法,使含有不育基因的可育株系逐步累积不育基因并增加了温光敏感性而育成玉米温光敏不育系 |
