Somaclonal variation has become common for many plant species including soybean (Glycine max (L.) Merr). The objective of this study was to test the presence of tissue culture derived morphological and yield variation in CO3 (Coimbatore 3) soybean cultivar. When compared with unregenerated parent or field grown plants, statistically significant variation was found in morphological characters and some yield characters like length of roots, shoots, petioles, internodal region and pods. The number of leaf nodes, number of flowers/ node, number of pods/ node, number of pods/ plant, number of seed aborted fruits, number of seeds/ pod, leaf area, fresh and dry weight of leaves and roots were also significant statistically (p0.05) except seed yield. Since the differences were not large, the results indicate that the tissue culture process is not necessarily detrimental to plant performance, which is an important consideration since tissue culture techniques are used in many genetic engineering methods.
