| Abstrak/Abstract |
Jackfruit (Artocarpus heterophyllus L.) is one of the most widely cultivated fruits in
Indonesia. This study was carried out during 2011–12 on the jackfruit germplasm planted at
the forestry and plantation area of Gunungkidul Regency, Yogyakarta Province, Indonesia.
The germplasm comprised a large collection of jackfruit accessions with 11 different origins,
i.e., East Java, Central Java, West Java, Bali, Medan, Pekanbaru, Lampung, East
Kalimantan, South Kalimantan, Kendari, and Lombok. This study aimed to assess the
variation in jackfruit provenances on the basis of morphological characters. Overall, 71
morphological characters were used to score and standardize the jackfruit land races. The Indonesian jackfruit provenances with different origins showed morphological variations in terms of fruit shape, fruit skin color, spike sharpness, spike density, and fruit flesh. UPGMA revealed that jackfruit provenances divided into two clusters with similarity coefficients ranging from 49.25% to 76.12%. The jackfruit genotypes collected from South Kalimantan Selatan and Lombok had the highest similarity index (76.12%). Thus, this finding might be useful for future jackfruit breeding programs and germplam conservation for future generations. |
