Abstract
臺農四號大豆是經由雜交育成的新品種。母本為早熟、豐產的農試H-11，父本為對銹病抵抗性強之PI 2004920於民國49年（1960）夏季交配，50年至53年（1961~1964）進行分離及選拔試驗，53年（1964）夏季固定，其品系代號為農試64～104，隨後參加初級、中級及高級品系試驗，並於民國55年（1966）起參加區域試驗之同時，加入地方試作。鑒於該品系在歷年各季作試驗中成績優異，深得好評，有推廣之價值，乃於民國59年(1970) 3月申請臺灣省政府農林廳雜糧作物新品種命名審查委員會，通過准予命名為臺農四號，並繁殖種子予以推廣。
“Tainung 4” soybean (Glycinc mzx (L) merr.) originated as an F8 plant selection from the cross (Nung-shih H-11 X PI 200492) in 1964. Hybridization, selection was made at Taiwan Agricultural research Institute. It was evaluated in regional uniform tests beginning in 1966 by Kaohsuing District Agricultural Station and cooperating Agricultural Station in Taipei, Hsinchu, Tainan, Taitung and Hualian. Before release, it was designated Nung-shih 64-104.
It has purple flowers, brown pubescence, yellow seed with light brown hila, and large seed (190-206 grams per 1000 seeds). It is resistant to lodging, and has determined with upright and breeder habit.
Tainung 4 was registesregistered in March 1970, and will be released in 1971. Taiwan Agricultural Research Institute will maintain breeder seeds.
Tainung 4 was developed because of its high production and resistant to rust disease (Phskopsora pachyrhizi, Syd.) It yields over 59.9% more than Tai-ta-Kaohsung 5 in the spring crop, and 8% in the summer crop, throughout the country. In the winter crop, it yields equal to above to Tai-ta-Kaohsuing 5 in southern area where is the main production area in Taiwan. And the more severe the rust disease, the bigger difference was found in yield.
