摘　　要：通过分析鲜食玉米鲜穗产量与主要农艺性状的相关性,筛选出适合右江河谷地区种植的高产优质新品种,推动鲜食玉米产业的发展。以2018年广西玉米创新团队百色综合试验站引进的25个优质高产抗病鲜食玉米新品种在右江河谷种植表现作为研究对象,采用灰色关联度分析法对其鲜穗产量与主要农艺性状进行分析,研究其在右江河谷特定气候条件下的主要农艺性状与鲜穗产量之间的关系。结果表明,鲜食玉米鲜穗产量与其相关主要农艺性状的关联度为:穗粗>百粒重>穗行数>穗长>株高>行粒数>秃尖>穗位高>出籽率,穗粗、百粒重、穗长对鲜穗产量影响较大,出籽率对鲜穗产量影响较小。建议在右江河谷地区鲜食玉米新品种的种植推广中,着重选择果穗较粗、籽粒较重、行粒数较多的品种进行种植推广。By analyzing the correlation between fresh ear yield and main agronomic characters of fresh corn,the new varieties with high yield and good quality suitable for planting in Youjiang River Valley were selected to promote the development of fresh corn industry.In this paper,25 new varieties of fresh maize of good-quality,high-yielding and disease-resistant introduced by the Baise Comprehensive Experimental Station of Guangxi Maize Innovation Team in 2018 were studied in the Youjiang River Valley.The relationship between the main agronomic characters and the fresh ear yield under the specific climatic conditions of the Youjiang River Valley was analyzed by grey correlation analysis.The results showed that the correlation between fresh ear yield of fresh corn and its main agronomic characters is as follows:ear diameter>100 grain weight>ear row number>plant height>row grain number>bald tip>ear position height>seed yield.It is suggested that in the cultivation and popularization of fresh corn varieties in Youjiang River Valley,the varieties with coarse ears,heavy grains and more row grains should be selected for planting and popularization.
