Karakteristik dan Pemanfaatan Plasma Nutfah Ubi Jalar (Ipomoea batatas (L.) Lam) di Pulau Moa, Kabupaten Maluku Barat Daya
Characteristics and Utilization of Sweet Potato Germplasm (Ipomoea batatas (L.) Lam) on Moa Island, Southwestern Maluku Regency
Abstract
Genetic resources exploration and conservation of sweet potato germplasm is very important to respond to the increased food
demand in the future. Therefore, the use of superior varieties with high yields represents one of the solutions. To produce superior
varieties, gene sources are needed that are suitable for the breeding targets. As an initial step, this study was conducted to characterize
sweet potato germplasms and to collect accessions or local varieties in Moa Island. Using the purposive sampling method observation
and description were conducted based on characters of vine and root parts of the plants, and eleven accessions were found, those were
Patatas Kuning A Patatas Kuning B, Patatas Madu A, Patatas Madu B, Patatas Maroke A, Patatas Maroke B, Patatas Maroke C,
Patatas Gila-gila A, Patatas Gila-gila B, Patatas Gila-gila C, and Patatas Telor. Cluster analysis was performed using 20
morphological characters, and a dendogram was generated which showed the degrees of similarities among the accessions. The
results of this study showed that sweet potato in Moa Island diverse based on shoot and tuber morphological characteristics. Based
on observations of morphological and other visual characteristics, preliminary descriptions of the eleven accessions found were
produced.
