We have collected and introduced 198 accessions of winged bean seeds from Thailand and 48 accessions from Sri Lanka.One cracked seed variety(SLS-84)which is suitable for industrial purpose,and 4 varieties of which the seed coat color is light yellow(TIS-141,-145,148 and -172)as that of soybean have been selected.Almost varieties were the shortday plants for flowering,but 41 varieties of them showed the insensetivity to the daylength.TIS-240 was thought to be one of the best varieties of all, that showed not only the insensitivity to the daylength,higy yield of young pods during summer but also somewhat the cold resistance.

收集引进泰国翅豆种子198份，斯里兰卡翅豆种子48份。选择了一个适合工业用途的裂种品种（SLS-84）和4个种皮颜色与大豆相同的淡黄色品种（TIS-141、-145,148和-172）。大部分品种均为短日照植物，但有41个品种对日照不敏感。TIS-240不仅对日照不敏感，夏季幼荚产量高，而且具有一定的抗寒性，是所有品种中最好的品种之一。
