中文摘要 | 由臺灣八個不同地區所蒐集的台南白玉米族群,經人工自交5個世代,並根據株型和穗型所選留的S5世代自交系合計291個為材料,以達生理成熟期之種子,每一自交系取10粒扁平型之種子進行籽粒重與果皮性狀之調查。結果顯示,所選留的自交系其發芽面果皮厚度之變域介於48 ~ 313 μm,總平均為132.4 μm,呈現非常態分佈;非發芽面果皮厚度之變域介於57 ~ 299 μm,總平均為140.1 μm,呈現非常態分佈;平均果皮厚度之變域介於53~ 298 μm,總平均為136.4 μm,呈現非常態分佈;果皮含量之變域介於3% ~ 14.88%,總平均為7.39%,呈現非常態分佈,可知不同的自交系間果皮性狀之變異極大。所選留自交系由嘉義、雲林、花蓮族群分離者具有較薄之果皮,而由屏東與台東族群分離者則具有較厚的果皮。性狀間之相關分析顯示自交系籽粒重與果皮厚度及含量間無相關性存在;發芽面果皮厚度、非發芽面果皮厚度、平均果皮厚度及果皮含量等性狀間呈極顯著正相關。 |
英文摘要 | 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 48-313 μm, 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. |
