Abstract: Eight wild Solanum namely, S. sisymbriifolium, S. torvum, S. sanitwongsei, S. indicum, S. integrifolium, S. khasianum, S. surattense, S. insanum and three Solanum amphidiploids of S. melongena "Uttara" x S. integrifolium, S. melongena "Dingaras Multiple Purple" (DMP) x S. integrifolium and S. integrifolium x S. melongena "Uttara" were tested using GA3 pretreatment for their seed dormancy and seed germination rate along with their potentiality as rootstock of tomato at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh. Influence of GA3 treatment for germinating seed in most of the wild Solanum was not found effective except S. sanitwongsei, S. surattense and S. integrifolium. Among the rootstocks, S. sisymbriifolium performed better for yield and yield contributing characters in tomato that those of other wild relatives, their amphidiploids, and non-grafted plants.
