摘　　要：以5个黄淮麦区主导小麦品种为试验材料,去雄后第1、3、5、7、9天观察柱头发育形态,并统计品种作为母本时的平均杂交结实率,分析品种柱头形态发育和母本的平均杂交结实率之间的关联性.结果表明:周麦18和百农207柱头去雄后1～9 d内形态发育稳健,在去雄后第9天退化不显著;周麦18平均杂交结实率最高为72.13%,百农207平均杂交结实率为61.53%,与周麦18差异不显著;西农979、良星99和偃师4110柱头去雄后第9天形态发育退化明显,这3个品种的平均杂交结实率则极显著低于周麦18.The stigma patterns of five dominant wheat varieties in Huanghuai wheat area were observed at 1,3,5,7 and 9 days after anthers removal,and the average seed setting rate was counted,the correlation between stigma patterns and average seed setting rate of five dominant wheat varieties was analyzed.The results showed that the stigma patterns of Zhoumai 18 and Bainong 207 were stable within 1~9 days after anthers removal,and the degeneration of stigma patterns was not significant on the 9th day after anthers removal;the average seed setting rate of Zhoumai 18 and Bainong 207 was 72.13%and 61.53%,respectively,which was not significantly different between them;The stigma patterns of Xinong 979,Liangxing 99 and Yanshi 4110 were degraded significantly on the 9th days after their anthers removal,the average seed setting rate of the three varieties was significantly lower than that of Zhoumai 18.
