An investigation was carried out at the experimental field of the Department of Agronomy of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during January 2012 through April 2012, to characterize different plant parameters of thirteen dwarf soybean (Glycine max L.) genotypes. A wide diversity among the genotypes in their physio-morphological characters including yield was recorded. Genotypes varied from days 36 in G00221 to 40 days in G00197 to initiation of 50% flowering. Genotypes G00042 took the longer time (80.7 days) for maturity, where G00351 took the shortest time (68.67 days). Pods number per plant was the highest (60.67) in G00207, while the lowest (15.04) in G00041. The highest number of seeds per pod (2.087) was obtained from G00046, while G00207 had the least (1.657). Weight of 100-seed was the maximum (16.34 g) in G00041and that was the minimum (10.55 g) in G00166.Among all the genotypes, G00207 produced the highest seed yield (4.23 t/ha). Contrary genotypes G00046 produced the lowest seed yield (1.43t/ha). The germination percentage of the thirteen soybean genotypes varied from 76.00% (G00042) to 86.66% (G00166). The terazolium-test showed that the highest viable seed (91.67%) was in the genotype G00166 and the lowest (85.67%) was in G00042. Electrical conductivity test showed that genotype G00204 had the minimum (18.84mS cm-1g-1) conductivity value, where G00343 had the maximum value (29.89mS cm-1g-1), which was followed by G00053 and G00221. It was concluded that variation in physio-morphology of the 13 genotypes would be useful in developing short duration high yielding soybean verities through genetic manipulation.
