大豆是世界上重要的農作物之一。培育優良大豆品種，選擇性狀優良的親代和鑑定優良後代是關鍵因素。分子標記輔助育種已被證明可以有效降低育種成本、縮短育種週期。
本研究使用並記錄了 23個大豆品種，其中包括 14個外國大豆品種和 9個台灣品種。 應用 50個已發表的簡單序列重複 (SSR) 標記來研究它們與 23個大豆品種性狀的關聯。 本研究的目的是鑑定與 23個大豆品種性狀相關的標記。在與性狀相關的35個SSR標記中，有7個與先前的研究結果一致。由於這些品種的譜系未知，這些SSR標記也被用來評估23個大豆品種之間的遺傳相似性。 結果表明，12號VI014685與其他22個品種差異最大。可以進行額外的研究和開發來完善這些標記，以識別 23 個大豆品種。
本研究提供了23個大豆品種的性狀和分子標記的基本資訊。這23個大豆品種的資訊將有助於後續大豆育種和其他分子標記相關研究的利用。

Soybean is one of the important crops in the world. To cultivate superior soybean varieties, the selection of parent plants with desirable traits and the identification of excellent offspring are crucial factors. Molecular marker-assisted breeding has been proven effective in reducing breeding costs and shortening the breeding cycle.
Twenty-three soybean were used and documented their traits in this study, including 14 foreign soybean varieties and 9 cultivars in Taiwan. Fifty published simple sequence repeats (SSR) markers were applied to investigate their association with the traits of the 23 soybeans cultivars. The purpose of this study is to identify markers that are associated with the traits of 23 soybean varieties. Among the 35 SSR markers associated with the trait, seven of them are consistent with the findings from previous studies. Due to the unknown pedigree of these varieties, these SSR markers were also employed to assess the genetic similarity among the 23 soybeans. The results indicated that No.12 VI014685 differs the most from the other 22 soybeans. Additional research and development can be carried out to refine these markers for the identification of the 23 soybeans.
This study provides basic information on the traits and molecular markers of 23 soybean varieties. The information of the 23 soybean will contribute to subsequent soybean breeding and other molecular marker-related research.
