Abstract
Ten microsatellite markers were used to investigate genetic diversity and genetic structure among 32 accessions of Jatropha curcas. Low levels of average genetic diversity were observed (H E = 0.160). A dendrogram produced by the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) based on Nei’s genetic distances revealed 3 groups among 32 accessions. The genetic differentiation (F ST ) among two groups was significant (P < 0.01). The model-based Bayesian clustering method indicated that a population structure (ΔK) was separated into two groups. The analysis of molecular variance (AMOVA) showed higher variability (63.753%) among groups than within groups (36.247%). These findings could assist in defining the best method of genetic conservation and studies in breeding programs for genetic improvement of J. curcas.
