摘　　要：[目的]为了解控制超甜玉米穗数对单株产量及主要穗部性状的影响。[方法]以超甜玉米金穗6号、金穗8号、金玉甜1号、超甜9701为试验材料,抽穗前选择生长势相似植株进行配对设计,抽穗期对其中一株去除第二果穗及以下所有果穗,成熟时将所得的单株产量及主要穗部性状(穗长、穗粗、秃尖长、穗行数、行粒数)的数据用SAS V9.2统计软件进行配对t检验。[结果]单株产量及主要穗部性状去穗与不去穗间均无显著性差异。[结论]控制穗数对超甜玉米产量及主要穗部性状影响不显著。[Objective]To research the effects of controlling the number of ear on yield and main ear characters of super sweet com.[Method]With super sweet com Jinsui6,Jinsui8,Jinyutian1and Chaotian9701as test m aterials,two plants with similar growth vigor were selected for matching design before earing.Then,ears below the second ear in one plant were removed during earing.Finally,data of yield per plant and main ear characters(ear length,ear diameter,bare tip length,row number,kernels per row)at mature stage were analyzed by t-test of SAS V9.2software.[Result]There was no obvious difference between remaining ears and removing ears in yield per plant and main ear characters.[Conclusion]Controlling the number of ears has little effects on yield and main ear characters of super sweet corn.
