Anatomical profile and genetic variability of sweet potato (Ipomoea batatas) cultivars in Banyumas, Central Java, based on RAPD markers

Samiyarsih S, Fitrianto N, Azizah E, Herawati W, Rochmatino. 2020. Anatomical profile and genetic variability of sweet potato (Ipomoea batatas) cultivars in Banyumas, Central Java, based on RAPD markers. Biodiversitas 21: 1755-1766. Indonesia has developed a food consumption diversification based on local sources. Sweet potato (Ipomoea batatas) is one of the tubers of carbohydrate sources in addition to wheat, rice, corn, potatoes, and cassava. It has a wide distribution, and high cultivars diversity produces a high variation on its morphology, anatomy, and genetic modification. The objectives of this research were to investigate the anatomical profile and genetic variability of eight sweet potatoes (Ipomoea batatas) cultivars found in Banyumas, Central Java, Indonesia. Anatomical profile was observed by the embedding method and subjected to analysis of variance. DNA amplification using Random Amplified Polymorphic DNA (RAPD) method with 10 primers, namely OPA-1, OPA-2, OPA-3, OPA-4, OPA-9, OPA-11, OPA-13, OPA-15, OPA-16, and OPA-18. The result of the anatomical study showed that eight sweet potato cultivars have significantly different (p
