CIMMYT小麦引入东北晚熟麦区的表现

Analysis on major agronomic characters of CIMMYT wheat

本文以2006、2007两年度从CIMMYT引入的小麦种质为材料,对其主要农艺性状进行了统计分析。结果表明:CIMMYT小麦种质主要农艺性状普遍表现偏矮、白粒、早熟、口紧不落粒、千粒重较当地品种高。因此,东北晚熟麦区在选择种质资源作为杂交亲本时应利用CIMMYT材料口紧,千粒重高等有利性状,同时应注重对前期抗旱性好、后期抗病性强以及抗穗发芽、偏晚熟材料的选择。

The experiment analysis major agronomic characters of CIMMYT wheat during 2006 and 2007.The results showed that CIMMYT wheat was short, white grain, early mature, fasten and it is also have a high 1000-grain weight as well as local varieties. CIMMYT materials fastenl high 1000-grain weight and other beneficial characters should be Paying a great attention. Meanwhile, strongly drought resistance at seeding stages, disease resistance in later, Preharvest Sprouting Resistance and late_maturing are also very important.
