Abstract:

    Pericarp characters was determined for kernels of 291 maize inbred lines of derived from eight Tainan-white population, planted at (TARI), Wufeng. Ten number of each inbred line were sampled for studying the pericarp characters. Thickness of the pericarp in the kernel germinal side ranged from 48-313µm, with overall average of 132.4 µm, and it showed non-normally distributed. The thickness of abgerminal side ranged from 57-299 µm, with overall average of 140.1 µm, and it also showed non-normally distributed. The average thickness ranged from 53-298 µm, which was non-normally distribution, with overall average of 136.4 µm. Pericarp content ranged from 3.0-14.88%, with overall average of 7.39%, and the data indicated non-normally distributed. The inbred lines derived from Chiayi, Yunlin, Hualin populations has thinner pericarp, and those derived from Pingtung, and Taitung had thicker pericarp. Non significant correlation existed among the kernel weight and other characters. However, germinal, abgerminal, average thickness, and pericarp content were highly correlated.
