KERAGAMAN GENETIK KAYU KUKU (Pericopsis mooniana Thw) PROVENANS SULAWESI TENGGARA PADA TINGKAT SEMAI

High demand of kayu kuku (Pericopsis mooniana Thw) has threatened existence of its populations in natural distribution. Ex situ conservation need to be carried out to protect them from extinction. Preparation genetic materials in nursery (seedlings) in term of seedlings was very important to support success of establishment of ex situ conservation plot. This research has objective to know the role of genetic factor to growth caharacteritics of kayu kuku seedlings from South East Sulawesi provenance. This research was arranged in Completely Randomized Complete Bock Design with 40 families as a treatment and 3 replications. The result showed that genetic diversity was observed affecting the growth characteristics such as height, diameter and sturdiness index among families. Estimation of family heritability (h 2 f) for height, diameter and sturdiness index were 0,94; 0,91 dan 0,91 respectively. Genetic correlation between height and diameter was found high positive namely 0,95. High genetic diversity found among families of kayu kuku seedlings was important to support success of genetic conservation and tree improvement activities.
