Keyword:  爆裂玉米普通玉米回交自交膨爆特性穗粒重;
Abstract: 对4个优良普×爆组合连续选优后代F3,F4,F5,BC1S1,BCiS2,BC1S3,BC2S1,BC2S2和BC2S3的爆花率、膨化倍数、穗粒重和百粒重的分析结果表明:各世代不同组合穗粒重和百粒重的平均值、变异系数以及优于亲本的植株数均存在较大差异,而爆花率和膨化倍数的差异较小;回交后代连续自交较直接连续自交穗粒重和百粒重有所减小,而爆花率和膨化倍数增大;各世代所有性状均存在较大变异,且以穗粒重最大,爆花率最小,而且随着选择世代的增加,穗粒重和百粒重均明显减小,而爆花率和膨化倍数明显增大;各世代爆花率和膨化倍数与爆裂亲本多呈显著或极显著正相关,而穗粒重和百粒重与亲本多呈显著或极显著负相关.
