为了探讨甜玉米主要农艺性状对产量和食用品质影响的主次关系,以24个甜玉米杂交组合为研究对象,对株高、穗位高、生育期、穗位叶长、穗位叶宽、穗长、穗粗、穗行数、秃尖长、单穗净鲜重10个主要农艺性状进行了田间调查,对鲜穗食用品质进行了室内蒸煮、品尝与鉴定,并与单穗鲜净重和食用品质进行了灰色关联度分析。结果表明:单穗净鲜重与其他各性状的关联顺序为穗粗>穗长>穗位叶宽>穗行数>生育期>穗位叶长>穗位叶面积>穗位高>株高>秃尖长,食用品质与其他各性状的关联顺序为穗位叶宽>秃尖长>穗位叶面积>穗长>穗位高>生育期>穗位叶长>穗粗>穗行数>株高。在甜玉米高产优质育种中,要注重对果穗长且粗、穗位叶宽且面积较大材料的选择。
In order to explore the primary and secondary relationship between the main agronomic characters of sweet corn and yield and edible quality, twenty-four sweet corn hybrid combinations were selected as the research object. The effects of different agronomic characters on the plant height, ear height, growth period, ear length, ear width, Spike length, ear diameter, ear number, bald tip length, net fresh weight of single ear 10 major agronomic traits were conducted in the field investigation of fresh ear quality of cooking, tasting and identification, and with a single fresh weight and Food quality was analyzed by gray relational analysis. The results showed that the fresh weight of single tassel was related to other traits by the following order: ear diameter> ear length> ear width> ear number> growth period> ear length leaf length> ear leaf area> ear height> plant height > Bald length, edible quality and other traits related to the order of ear width> bald length> ear leaf area> ear length> ear height> growth period> spike leaf length> ear diameter> ear number > Plant height. In high-yield and high-quality sweet corn breeding, pay attention to the ear length and thick, spike bit wide and large area of choice.
