摘　　要： 对 3 5个糯玉米材料的 1 1个性状进行了表型相关和通径分析 ,结果表明 :单穗重、生物产量与总产量有密切关系 ,单穗重对产量的直接作用最大 ,其次是生物产量。单穗重与生物产量呈显著正相关 ,净穗重与横径、穗长、轴粗呈 (极 )显著正相关 ,苞叶比不是主要性状 ,横径与轴粗呈极显著正相关。 The correlation and path analyses of 11 characters of glutinous maize were carried out. The results showed that the average weight of ear and biological yield were closely relative with yield. The greatest contribution to total yield is the average weight of ear, the second is biological yield. the average weight of ear was evidently relative to biological yield. Significant positive correlation was observed between the width and length of ear, width of axile and the net weight of ear. The proportion of ear to leaf was not a major agronomic character. Significant positive correlation was observed between the width a of ear and width of axile.
