对鲜食型超甜玉米组合产量性状进行相关及通径分析。结果表明：穗粗、穗长、行粒数与单穗净重、单穗鲜重显著或极显著正相关；秃尖长与穗行数、穗长显著或极显著正相关；叶脉数与株高、叶片数和行粒数极显著正相关。通经分析表明：穗长、穗粗、秃尖长、穗行数和叶脉数依次对单穗净重有直接影响；穗长、穗粗、秃尖长和叶片数依次对单穗鲜重有直接影响。

Correlation and path analysis on twelve yield characters of F1 in super sweet corn were studied. The results showed that net weight per ear and fresh weight per ear (with leaves) were significantly and positively correlated with ear diameter, ear length and kernels per row. While bare tip length was significantly correlated with rows per ear and ear length. The correlations between vein number and plant height, leaf number, kernels per row were also significant. The result of path analysis showed that agronomic characters influencing net weight per ear orderly were ear length, ear diameter, bare tip length, rows per ear and vein number, and influencing fresh weight per ear orderly were ear length, ear diameter, bare tip length and leaf number.
