综合顺序分类法鉴定小麦品种冬春性的研究

为了筛选适用于小麦冬春性鉴定的方法和指标,通过2006～2008年度连续试验,以37个小麦品种为试验材料,采用大田春播法,对小麦不同播种期的表现进行了研究,对苗穗期、春播抽穗率、幼苗习性、成熟期等指标和鉴定条件进行综合分析,确定春播抽穗率和苗穗期是鉴定小麦品种冬春性的可靠指标,提出采用综合顺序分类法评判品种的冬春性,并初步建立了小麦品种春播综合顺序分类法检测指标体系。

Study on Identification of Winterness and Sprigness of Wheat Cultivar by Comprehensive Order Classification Method

In order to screen identification method and indicators for wheat winterness and springness, through 2006 - 2008 continuous test, with 37 wheat cultivars as test materials, adopting field spring sowing method, the performance of wheat at different sowing period was studied. Ear period, spring heading rate, seedling habitats, maturity and identification conditions were comprehensively analyzed. It was found that spring heading rate and ear period are reliable indicators for identifying winterness and springness of wheat cuhivar. The comprehensive order classifica- tion method was adopted to judge the winterness and springness of wheat, the wheat cultivar comprehensive order classification method test indi- cator system was established.
