中文摘要 | 為探討臺灣及中國大陸在來種大豆之遺傳變異。於1993年夏作及秋作,將臺灣及 中國大陸各地區收集的 178 個在來品種種植於臺中中興大學農場。 調查株高、主莖節數、 分枝數、主莖數、主莖莢數、分枝莢數、總莢數、不稔莢數、單株粒數、單株粒重、百粒重 、開花期及成熟期等 12 個農藝性狀,種皮顏色、種臍顏色、花色、莖之生長習性、茸毛顏 色、成熟莢色及子葉顏色等 9 個質的性狀,及分析 5 種同功�t。參試種依地緣關係分成 7 個族群(東北族群、黃河上游族群、黃河下游族群、長江上游族群、長江下游族群、華南族 群及臺灣族群),調查不同族群大豆外表形態及同功�t的變異。 由逐步判別分析得知,夏、秋兩作最重要之判別性狀皆為開花期,兩作之族群形心在第一及 第二判別函數所構成的判別空間呈現族群間高緯度至低緯度的地理傾斜分化現象。黃河上游 、東北及長江下游族群之遺傳多樣性較大,臺灣族群較小。綜合上述得知,臺灣與中國大陸 各族群在來種大豆之外表形態有顯著差異,各族群間已有生態型分化。 |
英文摘要 | The objective of this study was to explore the genotypic variation of local soybean varieties (Glycine max (L.) Merr.) in Taiwan and the Mainland China. A total of 178 local varieties collected from Taiwan and various regions of the Mainland China were grown in the summer and the autumn crop seasons of 1993 in the Experimental Farm of Chung-Hsing University at Taichung. 12 agronomic traits, 9 qualitative traits were measured and polymorphism at 5 isozyme loci were analyzed. The test varieties were divided into 7 geographical populations thus the variations within each population and among the 7 populations were investigated. The results from discriminant analysis showed that days to flowering was the most important trait in separating these variety populations grown in the summer crop as well as the autumn crop. On the discriminant plane defined by the 1 st and the 2nd dicriminant functions, the distribution of the centroids of the 7 populations seemed to be well related to the latitudes of their collection regions. It revealed from the 9 qualitative traits there were higher genetic diversities in populations of Upperstream of Yellow River, North East and Downstream of Yangtze River. Taiwan population shown less genetic diversity. In conclusion, the morphological traits investigated were significantly different among the 7 geographical populations of local varieties of soybean in Taiwan and the Mainland China. Morphological variation among the 7 populations is attributed to different genetic materials. Different ecotypes of local varieties of soybean in Taiwan and the Mainland China had differentiated. |
