大豆「台南2號」係台南區農業改良場自亞洲蔬菜研究發展中心引進的優良品系中選出,並經品系試驗、區域試驗、品系試作、病害檢定及機械收穫性等試驗,顯示其具有豐產、質佳、抗倒伏、抗或中抗露菌病、蚽f及葉燒病,株型適合機械栽培收穫等特性,於民國82年5月經台灣省政府農林廳召集之作物新品種登記命名審查小組審查通過,予以登記。本品種採用雜交育種法育成,母本為SRF400,父本為PI181569,於70年春作雜交,而後代繁殖與選拔以混合法實施,至F7世代選出品系,代號台南育1號。在76年至78年間之品系試驗,其產量與對照品種台南選1號及高雄選10號之差異顯著,增產指數分別為12∼59%及11.5∼35.8%。在79及80年兩年區域試驗,春作及夏作的平均產量均較參試品種系高且穩定,表示對栽培環境適應性極佳。隨後進行地方性試作,春作更達2,866∼3,744公斤/公頃的平均產量。本品種屬於窄葉有限型品種,種子百粒重18∼21公克,生育日數春作需105天,夏作約95天,較對照品種高雄選10號提早2∼6天成熟,推廣後可納入本區春作或夏作輪作體系將有利於地力的增進與調整。

關鍵詞:大豆、雜交育種、區域試驗、適應性、抗病性。

Summary

Yun-Chia-Nan area is a major soybean production area in Taiwan, which occupies 83% of the provincial total.  Soybean is grown in this region both in spring and summer seasons for adjustment of paddy field utilization, increased soil fertility and farmers income.  Consequently, soybean cultivars suitable for grown in this region should be high yielding with early maturity and could be mechanically harvested.  The cultivar Tainan 2, a cultivar recently released by Tainan DAIS was developed under this goal.  Tainan 2 was developed and released in 1993 nder the cooperation of Tainan DAIS and Asian Vegetable Research and Development Center (AVRDC).  The variety was originated from the cross between SRF400 and PI181569 in 1981, the generations from F2 to F6 were advanced with bulk method and the superior line Tainan Yu 1 was selected in the summer crop of 1985.  Tainan Yu 1 had been recommended to join in advanced yield trial, regional yield trial and yield stability trial, as well as screening tests for resistance to the key pests and evaluation of agronomic characteristics were conducted between 1987 and 1993.  Finally, “Tainan Yu 1” was registered as “Tainan 2 “ in May, 1993.  The variety is characterized with the merits of high yielding, resistance to lodging, determinate type and suitable for machine harvesting.  The variety matured 2 to 6 days earlier than Kaohsiung san 10 and resistance to downy mildew, rust and bacterial pustule.  Anyway, its performance is adapted to spring crop and summer crop of Yun-Chia-Nan area.

Keywords: soybean, breeding, regional yield trial, adaptation, disease resistance.
