Research results indicated that: All varieties in the collection were growed and developed well in Spring season. Almost of the varieties revealed their characters in medium levels of evaluation scales, and it had medium duration. There was a diversification in the groundnut collection. And, two promising varieties were selected for test experiment at multilocation such at Thanh Ba district, Phu Thọ province and Hiep Hoa district, Bac Giang province.
