Abstract

Tamarillo (Chypomandra betacea Sent.) is a high land plant, that has been grown and developed in several regions in Indonesia, including in Toraja. However, the fruit that has a slightly sour sweet taste has not been widely used as nutritious food. The study aimed to characterize tamarillo plants that grow in the three developing areas. Data and information obtained from this activity can be used as an important information to determine the characters and to distinguish cultivars tamarillo plants in the area. The research was conducted using survey methods and direct observation in the field from March-September 2014 in three areas, namely Sapan and Kantun Poya District, North Toraja Regency, and Sangalla District, in Tana Toraja Regency, South Sulawesi Province. Data were collected for morphological characters of stems, leaves, flowers, fruits, and fruit nutrient content. Data were analyzed by simple statistical analysis and genetic relationship analysis using NTSys Program 2.1. The results showed that the toraja tamarillo had erect stems, round shape, height 2–5 meters, the leaves were dark green, flat type, slippery surface, facing upward. Purple flowers, the number of 10–12 fruits per cluster, with five stamens. Fruit type flat, oval, raw green color and when ripe striped maroon, production of 10–15 kg fruit/tree/year. The content of vitamin C was 30 mg/100 g, 2.6% of sugar, 85% of fruit juice content, 1.4% of total acid content, the amount of dissolved solids in the juice was 12.35%. The result of genetic relationship analysis using a 45 character traits showed that the cultivars Sangalla and Kantun Poya, as well as Sapan and Sangalla cultivars had a closed genetic relationship. Meanwhile, Sapan and Kantun Poya cultivars had much genetic relationship with different genetic trait.
