通过对５００个玉米杂交种不同穗部质量与数量性状关系的列联分析表明：玉米穗型与单株产量表现极显著正相关（Ｃ＝０．２９３４），玉米粒型与单株产量无显著相关（Ｃ＝０．１０５２），玉米穗型与粒型表现极显著正相关（Ｃ＝０．３７１７）；玉米筒型果穗，半马齿粒型的杂交种单株产量高，是玉米育种中穗部质量性状筛选的重要指标。
A series analysis of the relationship between quality and quantitative traits of different ear types in 500 maize hybrids showed that there was a significant positive correlation (P 0.2934) between ear type and yield of maize, and there was no significant difference between maize grain type and yield per plant (C = 0.1052). There was a significant positive correlation between ear type and grain type (C = 0.3717). The yield of maize tuberous and semi-dentate hybrid was higher in maize breeding An important index for screening panicle quality traits.
