摘　　要：通过对4个不同玉米自交系正反交组配的10个杂交组合,采用单因素随机区组试验,并对不同组合的F1的不同性状进行方差分析和品种间的差异性比较。研究结果表明:每个组合的正反交种子在大多数性状上差异不明显,这说明细胞核的遗传占主导地位,造成正反交差异的细胞质遗传所在比例较小。但每个组合的正反交组合均有差异明显的性状,同时每一性状均有正反交差异明显的组合,这说明细胞质的遗传在玉米性状表现起一定的作用。The four maize inbred lines and their 10 crosses were studied on differences of characters between maize hybrids and reciprocal Crosses. The results showed that there were not significance differences in most characters, but significant difference at least one character between maize hybrids and reciprocal cross for each cross.
