摘　　要：【目的】选育品质优、产量高、抗倒性强、抗病性较强、耐热性好、适应性广的超甜玉米新品种。【方法】2015年冬,应用“温带种质×热带种质”的甜玉米杂种优势模式,利用福建省农业科学院作物研究所最新育成的热带种质黄色超甜玉米自交系闽甜系T146与温带种质白色超甜玉米自交系闽甜系AS67测交配组,培育黄白粒超甜玉米新品种闽双色6号。2018–2021年闽双色6号分别通过了国家东南区、西南区鲜食玉米科企联合体区域试验。并于2021和2022年在广东惠州和福建建瓯开展千亩示范。【结果】国家区试结果:产量方面,闽双色6号在2018-2019年东南区试中,两年平均鲜穗产量13587.8 kg·hm^(-2),比对照品种粤甜16号增产7.6%,增产点率80.9%。在西南区试中,两年平均鲜穗产量13505.3 kg·hm^(-2),比对照品种粤甜16号增产3.6%,增产点率70%。抗逆性方面,鲜食玉米品种闽双色6号在田间自然发病的情况下,中抗小斑病,中抗/高抗纹枯病,中抗/高抗瘤黑粉病,中抗茎腐病,中抗/感大斑病和南方锈病。接种鉴定结果表明,该品种感丝黑穗病,感/中抗小斑病,感瘤黑粉病,高感纹枯病,感/中抗南方锈病。品质方面,经专家鉴定,国家东南区试验综合评分89.2分,国家西南区试验综合评分86.8分,均优于对照品种粤甜16号(85.0分);经扬州大学农学院理化品质检测,闽双色6号国家东南、西南两大区试平均皮渣率为11.8%,可溶性总糖含量为26.7%,还原糖含量为11.25%,优于对照品种粤甜16号的理化品质。分别于2020年和2022年通过国家农作物品种审定委员会审定(国审玉20200523、国审玉20220577)。惠州市马安镇千亩示范结果显示闽双色6号每公顷产量17982 kg,比对照增产5.9%,每公顷可增效7014元,品质品尝90.8分;建瓯市东游镇示范片每公顷产量18889.5kg,比对照增产9.44%,每公顷可增效7173.6元,品质品尝为89.7分,均优于对照,且建议�【Objective】A new variety of super-sweet corn characterized with the desirable properties of high-quality,high-yield,wide-adaptability,and strong resistance to lodging,diseases,and hot climate was bred.【Methods】A tropical yellow-kernel,super-sweet inbred Mintian T146 line of corn germplasm was crossbred with Mintian AS67,a temperate white-kernel,super-sweet corn inbred line newly developed by the Crop Research Institute at Fujian Academy of Agricultural Sciences.The new variety of corn was submitted to regional trials followed by test production held in two regions in the nation.【Results】Super-sweet Minshuangse No.6 bearing both yellow and white kernels on a cob was successfully bred in the winter of 2015.From 2018 to 2021,it was certified at the southeast and southwest regional trails for fresh consumption corn cultivars by the National Science and Enterprise Consortium.At the southeast regional trial from 2018 to 2019,Minshuangse No.6 delivered an average fresh ear yield of 13,587.8 kg·hm^(-2),which was 7.6%higher than that of the reference Yuetian No.16 with a yield point rate of 80.9%.A similar yield of 13505.3 kg·hm^(-2) was shown at the southwest regional trial that was 3.6%higher than that of Yuetian 16 with a yield point rate of 70%.On the resistance to diseases under natural infectious conditions in the field,Minshuangse No.6 was judged to be moderately resistant to the small spot disease,moderately to highly resistant to the grain wilt,moderately to highly resistant to the nodulation smuddery,moderately resistant to the stem rot,and moderately resistant to susceptible to the large spot disease and the southern rust.By artificial inoculation,it was identified to be susceptible to the head smut,susceptible to moderately resistant to the small spot,susceptible to the nodular smut,susceptible to the sheath blight,and susceptible to moderately resistant to the southern rust.In terms of quality,the comprehensive scores it received at the southeast regional trial was 89.2 and at the southwest 86.8
