英文摘要 | 直鏈澱粉含量與澱粉黏度測定值為白米主要之化學與物理特性,更是稻米食用與 加工品質之重要指標性狀,屬胚乳性狀。本研究利用水稻六親本全互交以進行該等性狀之遺 傳分析。由於直鏈澱粉含量與澱粉糊黏度測定值之測定無法以單粒法進行,本研究以混合同 組合諸遺傳異質 F �善_株所得諸遺傳異質 F �祕戽优馬挬�樣品, 數據經以 Griffing 與 Hayman 兩套方法分析, 並按直鏈澱粉含量、澱粉糊高峰黏度、熱糊黏度、冷糊黏度、崩解 黏度、回饋黏度與膠體黏度等分別討論。數據顯示七個品質性狀之顯性效應雖存在,但主要 受累加性基因所控制。 Griffing 與 Hayman 兩套分析顯示七個品質性狀正反交差異均不顯 著之事實指出,本研究參試親本符合 Hayman 氏正反交無差異之第二前題。受測各品質性狀 之顯性效應除熱糊黏度外,均肇因於單向顯性、基因分布未勻稱所呈之顯性與殘餘顯性等三 成份,而熱糊黏度之三類顯性成份中,基因分布未勻稱所呈之顯性值未具統計意義。 ively presented. It was evident that gene action in the parents studied was mainly additive for all evaluated endosperm characteristics, although dominance effects were also involved. The fact that reciprocal differences in both Griffing's and Hayman's diallel analyses were not significant indicated that Hayman's assumption (2) no differences between reciprocal crosses was met in this study. Date indicated that significant dominance gene effects were due to a directional dominance effect, an asymmetry of the gene distribution, and a residual dominance effect for all studied quality parameters except for hot-past viscosity, in which the effect of an asymmetry of the gene distribution was not significant. |
