摘　　要：为推广种植优良的玉米品种,以10个早熟玉米品种为供试材料对各参试玉米品种的产量品比结果、各主要农艺性状间与其产量关系进行比较及相关性分析。结果表明:在调查玉米生育期的9个性状中,对产量的贡献排名由小到大依次为生育期、秃尖、株高、穗长、穗位高、穗行数、行粒数、百粒重、穗粗,其中穗粗、行粒数和百粒重是影响产量的主要因素,提出选择生育期适中的,综合农艺性状好的品种是提高玉米产量的有效途径。在所参加试验的品种品系中结合性状与产量关系,DN270表现最好,产量相对较高。In order to promote the cultivation of excellent varieties of maize,the maize experiment was conducted by analyzing the correlation between the main agronomic traits and yield of maize varieties.The results showed that the main contribution to the yield Small to large was growth period,bald tip length,plant height,ear length,ear height,rows number per ear,seeds number per row,100-seed weight,ear diameter,among them,ear diameter,seeds number per row and 100-seed weight were the main factors influencing the yield.The effective way of increasing maize yield was to select maize with good agronomic traits.DN270 was the best line in all tested materials with high yield and good agronomic traits.
