In the light of mutual technical assistance, six soybean varieties, namely 'Bon minori' (2 lines), 'Enrei' (2 lines), 'Akiyoshi' and 'Hyuuga', were forwarded by registered mail from Japan to Vietnam in May, 1981. Due to its long postal course, soybean seed was only received in November 1981. A month later, seeds were planted on December 10, 1981, at the provincial seed farm of Kien Giang province and then harvested on February 26, 1982.
