Morphological Characteristics of Jackfruit at Pasar Manna District of South Bengkulu, Indonesia
Jackfruit (Artocarpus heterophyllus Lamk) is a plant species with high potential to develop. This species is commonly found in home gardens and adaptive to various environmental conditions. The use of jackfruit as a table fruit, vegetable, and medicine has remained limited. This study aims to assess the genetic diversity of local jackfruit in Pasar Manna District, South Bengkulu Regency, Indonesia, based on morphological traits and soluble solids concentration. Field observations and purposive sampling were employed, and plant morphology was identified using both qualitative and quantitative data based on the descriptors published by the International Plant Genetic Resources Institute (IPGRI, 2000). Morphological analysis of 10 jackfruit trees from five sub-districts in Pasar Manna District revealed 35 distinct traits, highlighting both differences and similarities among genotypes. The identified accessions—Tanjung Mulia1 (TM1), Tanjung Mulia2 (TM2), Ketapang Besar1 (KB1), Ketapang Besar2 (KB2), Padang Sialang1 (PS1), Padang Sialang2 (PS2), Pasar Bawah1 (PB1), Pasar Bawah2 (PB2), Pasar Mulia1 (PM1), and Pasar Mulia2 (PM2)—exhibited variations in plant morphology. TM1, TM2, and PS1 produced fruits with spheroid and ellipsoid shapes, weighing between 5.8 kg and 8.9 kg, with sugar content ranging from 11 Brix to 17 Brix. These findings indicate significant variation in fruit, stem, and seed morphology, suggesting adaptation to the local environment. This study contributes to the advancement of enhanced jackfruit germplasm in South Bengkulu, Indonesia.
