摘　　要：为研究鲜食玉米新品种的丰产性和稳产性,同时分析鲜穗产量与各病害性状之间的关系,应用方差分析、直观分析和相关分析的方法,分析了7个鲜食玉米新品种的丰产性和稳产性,以及产量与抗病性状之间的关系。结果表明:金王花糯2号的丰产性和稳产性最好,对鲜穗产量影响最大的是粗缩病(r=-0.364**),与产量呈极显著负相关,可见防治粗缩病是提高鲜食玉米品种产量的有效途径。By using the methods of variance analysis,visual analysis and correlation analysis,we studied the yielding ability and yield stability of 7 fresh maize new varieties,and analyzed the relationship between fresh-ear yield and disease resistance.The results showed that:Jinwanghuanuo No.2 had the best yielding ability and yield stability among the tested maize varieties;maize rough dwarf disease had the greatest effect on the yield of fresh ear,and there was a very significantly negative correlation between them(r=-0.364**).Thus,the prevention and control of maize rough dwarf disease is the effective way to improve the yield of fresh maize varieties.
