摘　　要：利用普通玉米自交系丹232与爆裂玉米自交系N04为材料,构建含有258个家系的重组近交系群体。在新乡、温县和郑州不同环境条件下进行田间试验,分析8个穗粒性状的表现及其环境稳定性。联合方差分析表明,各性状家系间和环境与区组互作显著或极显著;地点间穗长、穗粗、穗重、穗粒重和百粒重差异显著或极显著;除穗粗和秃尖长外,其余性状的家系与地点互作达到显著或极显著水平。F9群体各性状多呈连续正态分布,并表现超双亲分离。穗行数与穗长相关不显著;秃尖长与穗长、穗粗、穗行数、行粒数、百粒重相关不显著;其他各性状间均呈显著或极显著相关。Two hundred and fifty-eight RILs were developed from the cross between a dent corn inbred Dan232 and a popcorn inbred N04.Eight ear-kernel characters and their stability across different environments were ana-lyzed.Combined analysis of variance showed that the mean squares due to families,family ×replication interactions were all significant or highly significant for all characters.The mean squares due to environments were significant for ear length,ear diameter,ear weight,ear grain weight and 100-grain wei...
