Abstract

  Tainan ASVEG No.2 is a new variety of vegetable soybean, which was released by The Tainan District Agricultural Research and Extension Station and Asian Vegetable Research and Development Center in November, 2005. This variety was selected from the cross between GC91036-P and TVB-5 in 1994. The generation was propagated by single seed descent method. Tainan ASVEG No.2 was selected in F5 generation in the fall crop of 1996. The variety was evaluated in a series of new lines yield trials and regional yield trials. There are many good characteristics such as excellent flavor, high graded pod yield, superior resistance to major diseases and insects, large pod size and fresh green pod color. Therefore, it was released under the agreement of The New Crop Cultivar Naming, Registration and Inspection Committee Organized by the Council of Agriculture of the Executive-Yuan, R.O.C. The main characteristics of Tainan ASVEG No.2 were as fallows: Tainan ASVEG No.2 is a medium maturing cultivar and required approximately 82-91 days and 66-78 days in the spring and the fall crop, respectively. Plant height is about 43.0-48.1 centimeters in the spring crop and 37.3-43.0 centimeters in the fall crop. It has white flower and trifoliolate oval leaflets. The seed coat and hilum are yellow. The 100-seed dry weight is 36-42 grams. Average graded pod yield of Tainan ASVEG No.2 is 7850-13160 kg/ha, 119-171 pods per 500 grams, 43.9-55.3% with shelling rate in the spring crop and 5700-10552 kg/ha, 149-191 pods per 500 grams, 46.5-59.0% with shelling rate in the fall crop.

Key words; Vegetable soybean, Crossbreeding, Flavour, Disease resistance
