The ripening of Porang compound fruit (Amorphophallus muelleri Blume) in one cob does not occur simultaneously but moves forward from the distal region to proximal. The ripe fruit is red, almost ripe is yellow and unripe is green. The study aimed to examine the growth potential and polyembryonic properties of Porang seeds derived from red, yellow and green fruits. These seeds were grown in different media with the expectation the best plant growth can be obtained. This research was a factorial experiment which was arranged in a completely random design and each unit observation has three replication. The factor I was the source of seeds. Seeds came from various fruit colors. Each of them is red (R), yellow (Y) and green (G). Factor II is a planting medium which had 4 types, M1, M2, M3, and M4.  M1 is combination of soil and husk charcoal (70%: 30%), M2 = soil: cocopeat (70%: 30%), M3 = soil: husk charcoal: cocopeat (70%: 15%: 15%) and M4 = just soil (100%). The results showed that the seeds derived from red fruit and planted on medium 2 (soil: cocopeat = 70%: 25%) potentially producing the best plant. The seeds also showed 100% polyembryony at 182 days after planting. In addition, the first, second and third shoots (originating from one seed) have different in height, canopy diameters, and petiole diameter.
