摘　　要：通过对9个特早熟玉米杂交组合的产量及11个产量因素进行的灰色关联分析,对供试品种(系)进行综合评价,以期找出影响玉米产量的主要因素和表现较好的品种。结果表明,穗粒质量、穗质量、株高、穗粗4个农艺性状是影响玉米产量的主要因素。综合考察发现,品系新4-3×农1是产量和综合农艺性状最佳的组合,适于夏播。The gray correlative analysis was used to study the relationship between yield and 11 main yield factors of 9 ultra early maturing corn crossing combinations, The results showed that the main factors to decide the ultra early maturing corn yield among the 11 main agricultural traits were seed weight per ear, ear weight, plant height and ear diameter. In the integrate test it was indicated that the strains of Xin 4-3×Nong 1 was the best combination of yield and agronomic traits to fit summer planting.
