This study was conducted to determine the genetic variation and relationships between American accessions
of Jatropha curcas from different origins. The accessions from El Salvador showed the lowest plant
proportions, while two of the Mexican accessions (MCT10 and MCE06) showed the highest values in oil
yield. The principal component analysis explained 75.99% of the total variation in three components.
Repeatability analysis showed a low effect of the environment on the characters associated with oil
yield (R = 0.99), 100-seed weight (R = 0.98) and seed volume (R = 0.97), indicating a high level of diversity
among accessions and the feasibility of finding desirable characters in each collection, while offering
useful information for the selection of parental plants for use in crop improvement programs.
