| 摘 要： | 对鲜食型糯玉米42个组合产量性状进行相关和决策分析.结果表明:穗长、行粒数、穗粗、秃顶长和株高与单穗鲜重和单穗净重呈极显著正相关;穗长与秃顶长和行粒数呈极显著正相关.穗粗、行粒数、株高、穗长和穗位高对单穗鲜重和单穗净重有直接的作用;穗长、行粒数、穗粗和株高是提高杂交组合(F1)单穗鲜重和单穗净重的主要决定性状,穗位高则是主要限制性状.

| Abstract: | The correlation and decision analysis of ten yield characters of waxy corn F1 was studied.The results showed that the fresh weight per ear(with leaf) and net weight per ear were significantly and positively correlated with ear length,kernels per row,ear diameter,bare tip length and plant height.While ear length was significantly correlated with bare tip length and kernel per row.The result of path and decision analysis showed that agronomic characters influencing fresh weight per ear and net weight per ear were ear diameter,kernels per row,plant height,ear length and ear height.Ear length,kernels per row,ear diameter and plant height were main principal decision characters and ear height was main restricted character. |
