摘要[目的]探索鲜食玉米主要农艺性状对产量的影响,为红塔区优质高产鲜食玉米的选育和栽培提供理论依据。[方法]应用灰色
关联度分析法,分析糯玉米、甜糯玉米、甜玉米3类鲜食玉米品种的10个农艺性状与产量的相关性。[结果]3类鲜食玉米主要农艺性状
与产量的关联度不同,前4位的性状排序糯玉米为穗行数>单穗鲜重>穗粗>穗粒数,甜糯玉米为穗粒数>穗长>穗行数>单穗鲜重,甜玉
米为全株叶片数>生育期>穗位高>株高。[结论]影响糯玉米、甜糯玉米产量的主要因素都是穗部性状,在品种选育上要重视穗部性状
的选择;而影响甜玉米产量的主要因素都是营养生长性状,生育期长则积累的营养物质多,促使全株叶片数增多,穗位及株高增高,为营
养物质向穗部转移打下了基础,在品种选育上要重视营养生长性状的选择。
