Sapodilla is a fruit plant developed potentially in Indonesia because in addition to being consumed as fruit, it can serve as medicinal plant as well. Genetic information particularly on the chromosome of sapodilla is still limited. This study aims to get morphological information on its chromosome such as number, size, form, and karyotype of sapodilla from Bojonegoro and Wonogiri. This research was conducted in the Laboratory of Biotechnology and Plant Physiology, Faculty of Agriculture, University of Sebelas Maret Surakarta. The chromosome number of sapodilla from Bojonegoro and Wonogiri had similarity: 2n = 26, metacentric in shape. The chromosome size of sapodilla from Bojonegoro ranged between 1.46 ± 0.38 µm and 3.06 ± 0.48 µm, while that of Sapodilla from Wonogiri ranged between 1.49 ± 0.19 µm and 3.58 ± 0.27 µm. The karyotype formula of Sapodilla from Bojonegoro and Wonogiri was 2n=26m consisting of 13 metacentric chromosome pairs.

Key words: chromosome; karyotype; mitotic; Achras zapota
