  大豆新品種台南8號(黑珍)、9號(黑寶)係台南區農業改良場於2009年6月育成,採用雜交育種法,於2000年春作進行人工雜交,大豆台南8號(黑珍)之母本為黑豆台南5號,父本為丹波黑大豆。大豆台南9號(黑寶)之母本為毛豆高雄7號,而父本為黑豆台南5號。F2∼F6培育選拔採混合法,F6族群成熟期選拔優良單株,經品系試驗、區域試驗及一系列栽培試驗。結果顯示大豆新品種台南8號(黑珍)、9號(黑寶)具子實粒大、產量較現有推廣品種高、耐病蟲害,於2010年1月取得品種權。大豆台南8號(黑珍)生育日數春作106∼115天,秋作93∼98天。植株屬有限生長型。春作株高為約36.6~44.5公分,秋作為34~58.6公分。花紫色,葉為三小葉卵圓形。種皮及臍均為黑色,乾種子百粒重41.4∼49公克。春作子實產量每公頃2,833∼3,870公斤,秋作2,469∼3,372公斤,適合製作蜜黑豆、甘納豆或開發保健產品用。大豆台南9號(黑寶)生育日數春作106∼115天,秋作93∼98天。植株屬有限生長型。春作株高為36.6∼46公分,秋作為30.3∼62.8公分。花紫色,葉為三小葉卵圓形。種皮及臍均為黑色,乾種子百粒重36.5∼44.1公克。春作子實產量每公頃2,877∼3,947公斤,秋作2,616∼3,354公斤,適合開發各種加工產品,且耐露菌病及白粉病,有利於有機栽培。

Breeding of New Soybean Varieties “Tainan No.8” and “Tainan No.9”

Wu, C.H. and C.M. Wu

Abstract

  Tainan no.8 and no.9 are new soybean varieties developed by The Tainan District Agricultural Research and Extension Station in June, 2009. Tainan no.8 was selected from the cross between black soybean Tainan no.5 and Tamba black soybean. Tainan no.9 was selectied from the cross between vegetable soybean Kaohsiung no.7 and black soybean Tainan no.5. The generations from F2 to F6 were propagated by bulk method. These two varieties were selected in F6 generation and went through a series of standard field evaluations followed the official protocols. There are many good characteristics sush as large seed size, high yield and superior resistance to major diseases and insects. The main characteristics of Tainan no.8 were as fallows: Tainan no.8 is a medium maturing variety and required approximately 106-115 days and 93-98 days in the spring and the fall crop, respectively. Plant height is about 36.6-44.5 centimeters in the spring crop and 34-58.6 centimeters in the fall crop. It has purple flower and trifoliolate oval leaflets. The seed coat and hilum are black. The 100-seed dry weight is 41.4 to 49 grams. Average yield of Tainan no.8 is 2,833-3,870 kg/ha and 2,469-3,372 kg/ha in the spring and the fall crop, respectively. The main characteristics of Tainan no.9 were as fallows: Tainan no.9 is a medium maturing variety and required approximately 106-115 days and 93-98 days in the spring and the fall crop, respectively. Plant height is about 36.6-46 centimeters in the spring crop and 30.3-62.8 centimeters in the fall crop. It has purple flower and trifoliolate oval leaflets. The seed coat and hilum are black. The 100-seed dry weight is 36.5 to 44.1 grams. Average yield of Tainan no.9 is 2,877-3,947 kg/ha and 2,616-3,354 kg/ha in the spring and the fall crop, respectively.
