Tannia (Xanthosoma sagittifolium) is perennial plant cultivated for its edible corm, cormel and leaves. One of the major problems associated with its cultivation is planting material scarcity. So two propagation methods was examined: conventional and invitro. In the conventional propagation, corm pieces with 5g, 15g, 25g, 35g, 45g, 55g, 65g, 75g, 85g, and 95g were evaluated. In the in vitro propagation, shoot tip, leaf, petiole and corm explant types and different plant growth regulator types, concentration and combinations were used. In the conventional propagation, the optimum weight was...
