Abstract:

   All cross-combinations, excluding the reciprocals, were made among eight inbreding lines isolated from different originated areas of Tainan-white populations.  All F1 crosses and eight inbreding lines used as materials were used to study the xenia effect based on the kernel weight and pericarp characteristics.  Analysis of variance showed that genotypes, male, female, and male × female interaction were significant different on the pericarp characteristics.  In addition, the xenia effects were significant on the kernel weight, as well as thickness and content of pericarp at the same genotype.  The expression of xenia effects in kernel weight and might be due to the pollen parents with larger partly-dominant gene than that of the seed parents, and the dominant gene might be the increasing genes.  Xenia effects in pericarp thickness and content might be due to the pollen parents with larger partly- dominant gene than that of the seed parents, and the dominant gene might be the decreasing genes.

Key words:Maize, Xenia effects, Kernel weight, Pericarp thickness, Pericarp content
