The objective of this study was to determine the seed viability and growth of porang from several variations of cob parts. This study used a completely randomized design. Three replications were conducted with three treatments (cob section: tip, centre, and base). The percentage of sprouted seeds determines seed viability. Growth parameters measured were plant height, petiole cross-section, crown cross-section, tuber thickness, tuber cross-section, and tuber weight. Variation of seeds from the fruit cob did not affect the viability of porang seeds, but affected the size of plant height, petiole cross-section, crown cross-section, thickness, cross-section, and tuber weight. Seeds from the centre and base produced the best growth parameters than the tip, especially in harvested tubers. The heaviest tubers were 1.79±1.15 g (from the base), followed by 1.72±1.08 g (centre), and 1.09±0.77 g (tip). The seeds extracted from the centre and base are the best to use as seed sources.
