摘　　要：为鉴定豫北小麦冬春性的最佳播期,以半冬性小麦周麦18和弱春性小麦偃展4110为材料,对2月25日至4月15日期间11个播期2个品种的抽穗率进行调查统计.结果表明:3月1日至3月26日期间,周麦18的抽穗率变幅为0%-9.0%,偃展4110的抽穗率变幅为54.5%-81.5%,两品种之间的抽穗率表现差异性极大,可作为鉴定小麦品种冬春性的最佳播期.In order to identify the character of springness and winterness of wheat in North of Henan province,two wheat varieties （Zhoumai 18 and Yanzhan 4110） were sowed from 25th February to 15th April,and flower branch rate of the two wheat varieties in different sowing date was investigated and statistics analysed.The results showed that it was more different of flower branch rate from 0 to 9.0% of Zhoumai 18,and 54.5% to 81.5% of Yanzhan 4110, that the period of from 1st March to 26th March was the optimum sowing date to identify the character of springness and wintemess of wheat.
