摘要
在2001~2002年度对500份大麦种质资源耐湿性大田鉴定的基础上,2002年对其中12份耐湿性较好品种及10份耐湿性较差品种的耐湿性进行了水池鉴定。鉴定结果认为:大麦品种受湿害的程度与鉴定的条件(土壤保水性能、肥力)有关。在鉴定不同品种的耐湿性的差异时,应同时考虑各性状的绝对受湿值和相对受湿率,并以相对受湿率作为主要评价指标。22个品种在两年不同条件下的耐湿性鉴定结果基本一致,以浙农大3号和苏农16的耐湿性最好,耐湿性最差的品种为Araphes、Kapator、Lara等品种,7204(英)、余姚向天二棱的耐湿性需进一步进行鉴定。
The waterlogging tolerance of 12 high waterlogging tolerance barley varieties and 10 low waterlogging tolerance barley varieties which were selected from 500 barley germplasms according to field identified results in 2001 was more identified in pool in 2002.The results showed : the degree of barley waterlogging connected with the identified condition,Relative ratio of waterlogging in different trail was as main guideline for identifying different waterlogging tolerance ,meanwhile considering absolute value of waterlogging. The waterlogging tolerance of 22 barley varieties was almost sameness under different identified condition in different years. Zhenongda 3 and Sunong 16 were identified as the highest waterlogging tolerance barley varieties, Araphes ,Kapator and Lara were identified as the lowest waterlogging tolerance barley varieties, The waterlogging tolerance of 7204(England) and yuyaoxiangtian 2-row needell more identify.
