植物基因用以延續後代，不同基因表現不同的性狀，而基因在某些狀況下會轉移突變成重組，然隨著人類的需求，育種者將某些野生植物馴化為栽培種，其基因質因而狹窄化，對於病蟲害的抵抗性及耐旱性皆有減弱的趨勢，故擴大種原收集及保存為極重要的工作，以利時導入所需基因供品種改良用。有鑑於此，本所在行政院農委會及農林廳補助下建立牧草品種區，陸續收集牧草草種，並觀察登錄各草種之性狀，而為亦能提供農業界學者及植物愛好者認識及鑑定用，將常用草種包括禾本科五十四種及豆科三十九種之資料編輯成“台灣禾豆科牧草種原”專集中英文對照，此專集大部份以屬的形態特徵來整理，而屬下不同種亞種或品種間性狀之變異仍很大，因限於篇幅無法一一列出，此種遺漏或沒交代清楚，誠盼學者專家指正賜教，將感激不盡。

“台灣禾豆科牧草種原”編輯其間承屏東技術學院謝教授清祥台大農學院附設山地農場蔡副場長牧起台大農學院附設農場張技士聖顯恆春分所范主任基南及新竹分所卜主任瑞雄等賜稿，農委會林技正俊臣李技正春進農林廳林股長路拾及台大農藝系張教授新軒等提供寶貴意見，初稿又承台大植物系標本館黃博士星凡及成功大學生物系部教授長生分別審定豆科及禾木科資料，謹此致萬分謝意，而封面承本所技術服務系李夢熊先生設計，文稿承飼作系許秀碧小姐、陳富淑小姐及同仁等協助整理及校對，亦於此一併致謝。

Plant populations can keep descending for generations depending on genes. Different genes express different phenotypes. In certain cases, trangenosis, mutation and recombination might happen. To meet the requirement of humanbeings, some native species are selected and acclimatized to become cultivatedspecies. Thus, the genetic backgrounds might be narrowed and the resistances to diseases and insects and drought tolerance might be reduced. It becomes very important for germplasm collection and conservation to facilitate to introduce the desirable genes for breeding. The conservation of forage germplasms conducted at the Taiwan Livestock Research Institute has been financially supported by Council of Agriculture, Executive Yuan and Department of Agriculture and Forest, Taiwan Province for many years. The aims of the work are to maintainand enlarge the genetic diversity of forage species and evaluate them for utilization or for breeding materials. The monograph of "Forage Germplasms of Grasses and Legumes in Taiwan" including Gramineae 54 species and Leguminosae 39 species widely grown in Taiwan is written in both Chinese and English. Itcan provide information for agricultural workers, scientists and botanic interesters to learn and identify the forang species. There are still some limitations in the text of the book, more advices are highly appreciated.

We greatly appreciate the following scientists and researchers to help write and provide informations: Mr. R. H. Buu, Mr. S. H. Chang, Dr. Y. K. Cheng, Dr. C. N. Fan, Dr. C. H. Hsieh, Mr. C. C. Lin and Mr. M. C. Tsai and extend thanks to Drs. H. F. Huang and C. S. Kuo for reviewing the contents. We also sincerely appreciate Mr. M. H. Lee designing the cover and Ms. S. P. Hsu, Ms. F. S. Chen and the other colleagues helping compile and prove reading.
