Inter relationship of some Lai (Durio kutejensis Hassk.Becc.) cultivars originated from Indonesia, based on fruit morphology and nutrition content

Abstract

Lai is kind of fruit, which is originated from East Kalimantan Province, Indonesia. We found that some different cultivars of Lai were cultivated by farmers in Batuah Subdistrict of Kutai Kartanegara Regency. According to sensory evaluation of the fruit flesh and morphological characteristic of the fruit, we found that the cultivars have different respond and characteristic. In this report, we described inter‐relationship between the cultivars using cluster analysis based on morphological characteristic, nutritional content and sensory test. The fruits observed were harvested as they were commercially ripe and were kept for three days to get the ripen fruits. Based on fruit morphology, it was found that there were varieties among the observed Lai cultivars, except on number of its segments. The most significant similarity of morphological characteristics was found between Lai Hijau and Lai Semangka, which was about 44.1%. Based on nutritional content, it revealed that the most significant similarity was found between Lai Hijau, Lai Durian, Lai Belimbing and Lai Semangka of about 34.6%.
