Crosses of the 13(15) crosses with higher protein content in kernel composed by parents from different heterotic groups, so the inbreds with high protein content and high combining ability from different heterotic groups was the genetic basis for making high protein crosses.

在子粒粗蛋白质含量相对较高的13(15)个组合中，92.3%(80%)组合的双亲来源于不同的杂优类群；因此，来自不同杂种优势类群的高蛋白、高配合力自交系是组配蛋白质含量较高组合的基础。

In maize, the results indicated that the patterns of gene expression altered obviously in cross-fertilized kernels as compared to self-fertilized kernels, major difference of gene expression occurred in the qualitative level. Further analysis indicated that higher percentage of total differentially expressed cDNA was observed in highly heterotic hybrid than in non-heterotic hybrid.

对四个不同优势的玉米杂交和自交在种子发育前期基因表达研究表明，玉米杂交种子与自交种子在发育前期存在明显的基因表达差异，强优势的杂交组合与弱优势杂交组合之间表现差异的总cDNA比例存在极显著差异，进一步分析发现，杂交特异表达与杂种优势存在一定的正向关系。

The maize inbred line (Chang 453) from Millet Institute, Shanxi Academy of Agricultural Sciences was directly utilized. The high yield large-ear and early-maturing maize single-cross variety Tongdan 36 was bred by inbred-line Chang 453 and Tong 303. It built new heterotic pattern and broke through four heterotic groups limitation now. The heterotic pattern used was Gold-en-queen Х Xianfeng in American (Golden-queen Х P group).
