<![CDATA[ABSTRACT Identification using morphological characters has time consuming. Currently, identification using molecular markers has now been popular due to rapid, saving time and more precisely. Superjohn potato variety has been cultivated in North Sulawesi. However, the Superjohn potato variety has not been characterized using molecular markers. This research was aiming to identify “Superjohn†potato based on RAPD (Random Amplified Polymorphic DNA) markers. The research was conducted in field and laboratory. Field research was performed by taking some young leaves from “Superjohnâ€, Granola, and Atlantic variety from the field. Identification using molecular marker was conducted at laboratory. Nine RAPD primers were used to identify the superjohn variety. The nine primers were OPA-1, OPA-2, OPA-3, OPA-4, OPA-5, OPA-7, OPA-9, OPA-10, and OPO-1. The molecular identification revealed that “Superjohn†variety was different with Granola and Atlantic. OPA-9700 primer could be used for identification “Superjohn†variety while OPA-101000 primer was suitable for identification Granola variety. Keywords: Potatoes, variety, “Superjohnâ€, Granola, Atlantic, and RAPD ABSTRAK Penelitian ini dilakukan untuk mengidentikasi kentang “Superjohn†berdasarkan penanda RAPD (Random Amplified Polymorphic DNA). Penelitian dilakukan di lapangan dan laboratorium. Penelitian lapangan dilakukan dengan mengambil beberapa daun muda dari varietas kentang “Superjohnâ€, Atlantik dan Granola. Kemudian analisis DNA dilakukan di laboratorium menggunakan analisis RAPD. Berdasarkan penanda RAPD ternyata kentang “Superjohn†berbeda dari kentang Granola dan kentang Atlantik. Penanda RAPD OPA-9700 dapat digunakan untuk mengidentifikasi kentang“Superjohn†dan penanda RAPD OPA-101000 dapat digunakan untuk mengidentifikasi kentang Granola.
