黑豆新品種台南3號之育成
Development of New Black Soybean Variety Tainan 3
摘要
黑豆新品種台南3號係台南區農業改良場於民國87年5月育成，本品種的育成採用雜交育種法，於78年秋季進行人工雜交，親本母本為黑豆本地種，父本為恒春黑豆。雜交後代F2～F5的分離以混合法實施，F6世代選出優良品系代號TS81-125B（台南育3號），品系試驗、區域試驗及栽培試驗之結果成績優異，經台灣省農林廳新品種命名登記審查委員審查通過命名推廣。黑豆台南3號屬於中晚熟，生育期春作需116～126天，夏作需100～110天；籽實產量春作每公頃2,800～3,310公斤，夏作約2,485公斤，都較黑豆本地種顯著增產。台南3號種皮黑色，子葉綠色，百粒重10～13公克，植株高度45～77公分，主莖節數14～16個，豆粒的品質優良，適合豆粉加工，外觀色澤、香味及食味均優於進口黑豆。台南3號對光敏感，由於粒小及生草產量高，亦適合作為夏季綠肥作物。

Tainan 3 is a new variety of black soybean, which was developed by Tainan DAIS in May, 1998. This variety was selected from the cross between Ching-Ren-Udow ×Hengchun-Udow in 1989. The generations from F2 to F5 were using bulk method. The breeding line named ”Tainan yu 3” was selected in F6 generation in the fall crop of 1992. Tainan yu 3 was evaluated in a series of preliminary yield trials during 1993~1995 at the experimental field of Tainan DAIS, Yen-suei, Pu-tzu and Yen-chang. Tainan yu 3 which performed best was approved by the examination committe to register as Tainan 3.The main characteristics of Tainan 3 were as follows:Tainan 3 is medium to late maturing black soybean cultivar and required approximately 116~126 days and 100~110 days to mature respectively, in the spring and the summer cropping seasons in Yun-Chia-Nan area.Average seed yield of Tainan 3 is 2,800~3,310 kg/ha in the spring crop and is 2,485 kg/ha in the summer crop that outyields than the local black soybean variety.The color of seed coat is light black and cotyledon was green. Plant height is about 45~77 cm with 14~16 nodes along main stem. Hundred-seed weight is 10~13 g. The seed quality is better than imported black soybean for processing powder.Tainan 3 is photosensitive is small in seed size, high yielding biomass. Therefore it is also suitable for green manure at summer crop.
