摘要
以高油玉米群体IHO的3个农艺性状比较优良、籽粒粗脂肪含量高的稳定品系为父本与生产上广泛应用的6个优良自交系为母本杂交,通过对亲本及其杂交当代籽粒的粗脂肪含量和百粒重的初步比较分析,发现杂交当代籽粒粗脂肪含量和百粒重都具有杂种优势效应和花粉直感效应,认为可通过合理利用该效应来提高玉米籽粒产量和改进籽粒品质。
3 elite substitution lines which have excellent agricultural characters and high fat content crossed with 6 important common corn inbred lines. The Xenia and heterosis effects at F1 embryo stage were studied by comparing kernel fat content and 100-kernel weight at F1 embryo stage with their parents. The results showed that there were heterosis effects and Xenia effects on kernel fat content and 100-kernel weight at F1 embryo stage. It is possible to increase the yield of kernel and improve the quality of kernel by using these effects.
