摘　　要：通过 16个玉米组合棒三叶叶面积大小的比较及其与单株穗重、粒重的相关性研究 ,揭示了杂交种棒三叶的特征特性。初步说明玉米杂交种棒三叶、穗位叶叶面积与单株穗重呈显著的正相关关系。此结论可作为玉米育种工作者早期判断组合优劣的重要依据 ,大大减轻工作量 ,减少优秀组合的遗漏 。This paper compared areas of three ear leaves of 16 corn hybrids, studied correlation of areas of three ear leaves with weights of ear and kernel of signal plant,predicted it's characters. The results preliminary showed that areas of three ear leaves has significantly positively correlated with ear weights of signal plant. It will help breeder to judge good or general combination in early period, to decrease the working amount and to avoid the loss of good combinations, at the same time, the theory of heterosis can be enriched.
