| 摘 要： | 【目的】为满足玉米消费市场的需求，选育兼具甜玉米和糯玉米风味的优良鲜食玉米品种。【方法】对由甜糯双隐性（wxwxsh2sh2）玉米自交系与优良糯玉米自交系杂交组配鉴定筛选出的较好的20个甜糯玉米杂交组合，采用问比法进一步种植筛选，调查农艺性状、产量及品质性状，并依据玉米品种审定标准进行综合评分。【结果】参试玉米组合中，综合评分〉90．0分的有14个，排名前10的组合是SW13〉SW07〉SW03〉SW20〉CK〉SW15〉SW11〉SW05〉SW06〉SW16，组合SW13、SW07、SW03、SW20综合评分高于CK。【结论】组合SW13、SW15、SW07、SW03和SW20生育期、苗期长势、植株性状、抗倒性、抗病性、丰产性、外观品质和品尝品质等综合评价优于其他组合，可进一步参加广西区域试验。

| Abstract: | Objective]The present experiment was conducted to screen high quality fresh sweet-waxy maize varieties in order to meet the demand of fast increasing maize market. Method]The agronomic traits, yield and quality characters of 20 sweet-waxy maize combinations selected in 4 crop experiments of 2 years were investigated by planting in interval contrast design. All the varieties were graded according to maize variety accreditation standards. Result]Among the 20 combinations screened, 14 recorded the comprehensive score of more than 90.0. The top 10 combinations in order of their scores were as follows ：SW13 〉SW07〉SWO3〉SW20〉CK〉SW15〉SW11 〉SW05〉SW06〉SW16. The first four combinations amongst these viz., SW13, SW07, SW03, SW20 would take part in the next regional trial in Guangxi. Conclusion]The combinations SW13, SW07, SW03, SW20 and SW15 showed best agronomic and yield traits, and would be selected in maize regional trial in Guangxi. |
