摘　　要：对３份生态核雄性不育小麦、２０份不同生态型父本及６８份两系杂种在长沙进行一个年度或连续两个年度的分期播种试验，研究其育性表现及杂种双亲恢保关系．结果表明：３个不育系均属短日低温敏感型雄性核不育小麦，ＥＳ－９，ＥＳ－１１属“浅不育”类型，ＥＳ－１０属“深不育”类型；父本和杂种育性程度不同地受温度影响，年度内及年际间育性均有较大差异；３个不育系恢复源范围大小顺序依次为ＥＳ－１１，ＥＳ－９，ＥＳ－１０；南方麦区春性品种（系）具有较高的恢复能力，是３个不育系的共同恢复源．The fertility performance and sterility restoring maintaining relationship of two line hybrid wheats were studied by changing the sowing dates of 3 ecological genic male sterile (EGMS) wheats,with the material of 20 male parents with different ecotypes and 68 hybrids.The results obtained were as follows:the 3 EGMS wheats belong to the shorter daylight lower temperature sensitive male genic sterile type.ES 9 and ES 11 belong to the light sterility type,while ES 10 belongs to the deep sterility type.Fertilities of different male parents and hybrids were influenced in different degrees by temperature,and their altering tendencies in one year or two years just resembled that of the 3 EGMS wheats.The order of restoring sources of the 3 EGMS wheats was ES 11>ES 9>ES 10.Spring cultivars cultivated in south China possessed higher general restoring ability (GRA) than winter or semi winter cultivars in north China,and had become the common restoring sources of the 3 EGMS wheats.
