Abstract:
Coconut belongs to the Palmae family which is a versatile plant and has high economic
value. Bandar Laksamana Sub-district, Bengkalis Regency is one of the largest potential
coconut producing districts in Riau. Coconut diversity based on agronomic characters
has not been supported by scientific data. The purpose of this study was to characterize
the diversity of coconut based on agronomic characters in Bandar Laksamana District,
Bengkalis Regency and analyze their kinship relationships. This research was conducted
using the exploration method. Kinship relationships of coconut species were analyzed
using the NTSys pc 2.02 application. Data obtained were presented in tables, figures,
and analyzed descriptively. Results of this study obtained 12 variations of coconut
which are classified into 10 types of coconut (Cocos nucifera Linn. var. macrocorpu),
(Cocos nucifera Linn. var. viridis), (Cocos nucifera Linn. var. eburnea), (Cocos
nucifera Linn. var. nana), (Cocos nucifera Linn. var. pumila), (Cocos nucifera Linn.
var. pretiosa), (Cocos nucifera Linn. var. saccharina), (Cocos nucifera Linn.
"Hybrid"), (Cocos nucifera Linn. var. regia), (Cocos nucifera Linn. var. alba). Based on
28 agronomic characters, coconuts were divided into two main groups with similarity
coefficient values of 0.03-0.50.
