    Two varieties of bambara groundnut (Vigna subterranean L. Verdc) were evaluated for seed quality under different seed moisture contents between 8, 10 and 12%, and the seeds were stored under ambient condition for six months. Songkhla 1 maintained high germination percentage (91.11%) and high germination index (24.43) after storage for six months, whereas TVsu 1221 showed low germination percentage (54.67%) and germination index (14.83) in two months after storage. Differences among seed moisture contents were low and seed moisture content of 12% was better than seed moisture content of 8% for germination percentage and germination index. Variations between bambara groundnut varieties and seed moisture contents were low for shoot length and seedling dry weight. These parameters seemed to be not suitable for evaluation of seed quality of bambara groundnut.

    Result showed that the days to 50% flowering among four bambara groundnut genotypes ranged from 31.75 days to 34.25 days and days to harvest ranged from 93 days to 125 days. TVsu 89 had the lowest days to 50% flowering of 31.75 days and days to harvest of 93 days. TVsu 89 had lower agronomic traits than check variety (Songkhla 1), but it was not different from check variety for fresh pod yield and dry pod yield. Correlation analysis indicated that harvest index was positively and significantly associated with fresh pod yield and dry pod yield.
