Abstract

Seed size and protein and tannin contents were determined on 25 accessions of bambara groundnut currently available in Ghana, using dried seeds 8-10 weeks after harvesting. The 100-seed weight varied from 34 to 63 g. The protein and tannin contents were 14.1 to 23.1% and 0.25 to 2.27% (dmb) respectively. Tannin concentration increased with increase in testa colour and eye pattern colour. Selecting accessions with high protein and low tannin, with large or medium seed size should improve the quality of bambara groundnut.
