摘　　要：以2014年四川省鲜食甜玉米区试9个甜玉米新品种为研究对象,采用灰色关联度分析法,分析水溶性总糖与10个主要农艺性状的关系。结果表明,甜玉米水溶性总糖与主要农艺性状关联度的大小依次为穗行数>穗粗>百粒重>穗长>出苗-采收期>穗位高>株高>行粒数>出籽率>秃尖,穗行数是影响甜玉米水溶性总糖含量的主要因素,其次是穗粗、百粒重,秃尖对甜玉米水溶性总糖含量影响最小。Taking 9 new varieties of fresh- food sweet corns regional test in 2014 of Sichuan as the study materials.Relation of water soluble sugar content of sweet corn and 10 main agronomic characters were analyzed by grey correlation degree analysis.The results for ranked list of grey correlation degree of water soluble sugar content and main agronomic characters showed,ear rows 〉 ear diameter 〉100 kernel weight 〉 ear length 〉 period of seedling emergence to harvest 〉 ear height 〉 plant height 〉 kernel row number 〉 rate of bear ing kernel 〉 bald tip length.Kernel row number was the main factor to effect water soluble sugar content of sweet corn.The next was ear diameter and 100 kernel weight.Bald tip length had less effect on water soluble sugar content.
