Abstract

Kalimantan Island is rich in genetic resources and species diversity of Durio spp. plant. The large number of Durio species that grow in Kalimantan illustrates that this area is the most important distribution center for durian relatives. The best-known edible durians are Durian (Durio zibethinus). However, Kalimantan also has various types of Durian that are not yet widely known and have superior potential. One of the unique and exotic plants is the red flesh Durian in East Kalimantan, Indonesia. The fruit of this plant is unique because it has red flesh. At present, there is no morphological identification of this East Kalimantan Durio graveolens plant. The study aimed to identify the morphological character of Batuah D. graveolens from East Kalimantan, Indonesia. This research was carried out by collecting data and information about the morphological characteristics of the plant and fruits. The results of the study successfully identified Batuah D. graveolens from East Kalimantan as a plant diverts from another Durio spp. plant known like D. zibethinus and D. kutejensis especially for red flesh character.

Abstract

Kalimantan Island is rich in genetic resources and species diversity of Durio spp. Of the 27 durian species in the world, 18 species are found in Borneo. The large number of Durio species that grow in Kalimantan illustrates that this area is the most important distribution center for durian relatives. Two of the best-known edible durians in East Kalimantan are Durian (Duriozibethinus) and Lai (Durio kutejensis). However, as a plant with a cross-pollination mechanism, there are many results of natural crosses between the two. The study aimed to identify Durian x Lai plants in Loa Kulu, Kutai Kertanegara, East Kalimantan Province, Indonesia as the superior local fruit crops potentially agribusiness industry. This research was carried out by collecting data and information about the morphological characteristics of the plants and fruits from D. Zibenthinus x D. Kutejensis. The results of the study successfully identified 6 potentially superior plants that are believed to be the result of a cross between D. Zibenthinus x D. kutenjensis. The 6 potential superior plants were found to have different morphological characters. This is the initial identification and being a basis of the next research phase, which is to identify the morphology of trees, flowers, and fruit to obtain new cultivars crossing D.zibenthinus and D. Kutejensis which have superior potential as superior commodities from East Kalimantan.

Abstract

The large number of Durio species that grow in Kalimantan illustrates that this area is the most important distribution center for durian relatives. Two of the best-known edible durians in East Kalimantan are Durian (Durio zibethinus) and Lai (Durio Kutejensis). Several studies have been conducted to determine the effect of calcium on the quality of fruits. However, very little information was obtained regarding the effect of Ca on the quality of lai-durian fruit. This research was carried out by collecting data and information about Fruit performance and edible part nutritional value three D. zibenthinus x D. kutejensis plants. The five potential superior plants have some similar in rind moisture factor, ash content, water content, total fat, crude protein, and total dissolved solids. However, there is a difference in flesh thickness which indicates that LK4 has the thickest flesh thickness with an average of 9mm, while LK5 shows the thinnest average flesh thickness of 4mm. Meanwhile, when viewed from total carbohydrates, LK3 fruit has the highest total carbohydrate content compared to other fruits, which is 37.477 and energy is 180.357 kcal. This study indicates that there is a negative correlation between fruit peel size and calcium content. In large Lai-durian fruits such as LK4 fruit there is a lower amount of calcium than other fruits.
