Identification of dominan maternal and paternal line characters influence to new find sahang durian plant morphological characters as nature cross-pollination result

Abstract

There are two types of durian that are commonly consumed and grow in Kalimantan. Two of the bestknown edible durians in East Kalimantan are Durian (Durio zibenthinus) and Lai (Durio kutejensis).

However, as a plant with a cross pollination mechanism, there are many character results of natural

crosses between the two in nature. Sahang durian trees were found grow in Kutai Kertanegara, East

Kalimantan, Indonesia. There is a question whether this variety is a new species of durio plant or this

is the result of a nature cross-pollination between D. zibenthinus and D. kutejensis. The aim of this

research is to know and identify morphological character of sahang durian from East Kalimantan,

Indonesia. This research was carried out by exploration information by interviews with the durian tree

owner

farmers, then characterization of durian plant used International Plant Genetic Resources Institute (IPGRI) morphological characteristics. This study successfully identified the character of sahang durian as descendants of both durian species with combination character from its parents (D. zibenthinus and D. kutejensis). Sahang durian has some superior characters like medium-sized fruit, orange color aril, odorless like D. kutejensis, but has a green color fruit skin, sweet taste, soft and creamy aril like D. zibenthinus. Sahang durian character is more dominantly influenced by D.kutejensis character, its indicate maternal line has dominant influence compare to paternal parent. Therefore, it can be stated that the Sahang durian is a plant derived from the natural cross between D.zibenthinus and D.kutejensis.
