Type: article
Abstract: The Katokkon pepper, an indigenous variety from Tana Toraja, Indonesia is found to be hold a significant local value and is recognized for its antioxidant potential. This research presented the first cytogenetic analysis of the Katokkon pepper which revealed a diploid chromosome number of 2n = 24, with predominantly metacentric chromosomes. The karyotype formula was determined to be 2n = 2x = 24 = 12m. The highest mitotic index (34.24%) was recorded at 07:00 a.m., indicating the peak of mitotic activity. These findings provided essential insights into the chromosomal structure and evolution of the Katokkon pepper, laying the groundwork for future breeding programs which enhances this unique variety.
