摘　　要：本研究以2020—2021年度河南省区试95份小麦新品种为研究对象,通过田间春播的方法对区试小麦品种的冬春性类型进行鉴定,为品种审定提供科学依据。结果表明:春播第二播期条件下,12份新品种鉴定为春性类,春性类品种均全部抽穗,抽穗率为38.5%~95.0%,苗穗期为46~53 d,成熟情况表现为未成熟、基本成熟和接近成熟;83份新品种鉴定为冬性类,大部分品种未抽穗,抽穗率为0~23.9%,成熟情况均表现为未成熟;春性类品种占参试品种总数量的12.6%,冬性类品种占参试品种总数量的87.4%。春播第一播期条件下,所有冬性类品种鉴定为半冬性。春播第三播期条件下,春性类品种中5份品种鉴定为春性,其余7份品种鉴定为弱春性。In this study,95 new wheat varieties in the regional trial of Henan Province from 2020 to 2021 were taken as the research object.The growth habits of wheat varieties in the regional trial were identified by the method of field spring sowing,which provided a scientific basis for variety approval.The results showed that under the condition of the second stage of spring sowing,12 new varieties were identified as spring varieties.All spring varieties were heading,the heading rate was 38.5%-95.0%,the seedling heading period was 46-53 days,and the maturity was immature,basically mature and nearly mature.83 new varieties were identified as winter varieties,most of them were not heading,the heading rate was 0-23.9%,and the mature condition was immature.Spring varieties accounted for 12.6%of the total number of tested varieties,and winter varieties accounted for 87.4%of the total number of tested varieties.Under the condition of the first stage of spring sowing,all winter varieties were identified as semi-winter varieties.Under the condition of the third stage of spring sowing,5 varieties of spring varieties were identified as spring varieties,and the other 7 varieties were identified as weak spring varieties.
