Identification of morphological characters and kinship of coconut genotypes (Cocos nucifera L.) in Aceh Tamiang District, Aceh

Abstract

Coconut productivity in Indonesia was relatively low, whereas the potential for coconut production can reach 3-5 tons of copra/ha/yr. Collection of genetic material or sources of genetic diversity of coconuts that are indispensable to plant breeders. This research was conducted using a descriptive survey method based on books IPGRI (International Plant Genetic Resources Institute) coconut descriptor guide with sampling technique by accidental sampling. Cultivation of coconuts in Tenggulun, Seruway and Rantau Districts consists of land and yard coconut with monoculture or polyculture cropping patterns. The research conducted on 27 genotypes of coconut, which research showed that all of the genotype coconut identified were genotypes of coconut Dwarf. Morphological characterization results were found for canopy shape (round, half round, X-shaped silhouette, V-shaped), flowers (normal and still covered with leaf sheaths), fruit (oval, ovate, angled, round), shell (pointed, ovate almost spherical, oblate). From the 27 genotypes, there are genotypes that are good as a source of parents, namely AS26 with the character of heavy and thick flesh and AS4 with a large number of fruits.
