| 摘 要： | 通过来源不同的20个高油系和5个普通系杂交当代和后代籽粒油分花粉直感效应及遗传分离特点分析，发现N1680高油系的杂交当代籽粒和F2籽粒油分含量接近于高油亲本，表现出显性基因的遗传特征；同时，F2籽粒油分还存在明显的超高亲优势。因此推测该系可能存在显性高油基因，并与其他基因存在互作效应。

| Abstract: | Twenty high oil corn(HOC) inbred lines and five normal corn(NOC) in bred lines from different germplasms were used to make NCII crosses to analyze oil xenia effects and segregation of F 2 kernels. Results showed that dominant high oil gene might exist in high oil line N1680 based on its significant oil xenia effect and F 2 oil concentrations near to the high oil line. Besides, oil concentration distribution analysis showed that transgressive segregations were also obvious in the F 2 kernels, which confirmed further that the gene had interaction with others. |

| Keywords: | maize high oil dominant gene gene interaction xenia transgressive segregation |
