摘　　要：本试验以9个子粒品质差异较大、遗传背景不同的爆裂玉米优良自交系为材料,就爆裂玉米的产量、膨胀倍数与主要数量性状的相关性进行通径分析。结果表明,爆裂玉米产量与主要数量性状的相关系数大小依次为:行粒数>穗长>穗粗>百粒重>株高>茎粗>出子率>穗行数>穗位高>秃尖长>淀粉含量;膨胀倍数与主要数量性状的相关系数大小依次为:膨化体积>爆花率>淀粉含量>行粒数>穗位高>穗长>茎粗>小区产量>株高>穗行数>出子率>秃尖长>百粒重>穗粗。Using fine inbred lines of popcorn as a material, which grain quality and genetic background are very different, correlation of their yield, popcorn inflation multiple and the with main quantity characteristics were path analyzed in the paper. The results showed that the correlation coefficient between the yield of popcorn and the main quantity characteristics were in following sequence： number of seeds per row〉 ear length 〉 ear thickness 〉 hundred grains weight 〉 plant height 〉 stem thickness 〉 seed rate 〉 number of lines per ear 〉 ear height in plant 〉 bare point length 〉 starch content; the correlation coefficient between the inflation multiple and main quantity characteristics were in following sequence： expansion volume 〉 popcorn rate 〉 starch content 〉 number of seeds per row 〉 ear height in plant 〉 ear length 〉 stem thickness 〉 yield of a plot 〉 plant height 〉 number of lines per ear 〉 seed rate 〉 bare point length 〉 hundred grains weight 〉 ear thickness.
