While the short-term goal is to find information on average performance and predictive value of genetic parameters of agronomic traits Jatropha. This research was conducted at the experimental farm of agriculture faculty unsyiah which began in March 2013 to June 2013.This research used a randomized block design with 10 patterns of non-factorial treatment that G1, G2, G3 genotypes of Jatropha is derived from ecotype Tebingtinggi, G4, G5, G6 genotypes of Jatropha is derived from ecotype Dolok Merawan, G7, G8, G9, and G10 genotpes of Jatropha is derived from ecotypes Abdya with each henotype were repeated three replications in order to obtain 30 units of experimental units. The parameters measured were the growth of plant height, number of leaves, leaf lengt, leaf width, stem diameter, age 30, 45, 60, 75 and 90 days after planting and crop canopy age 90 days after planting. The result of this research indicated that there is no significant effect between the appearance of the growth of Jatropha as a result of treatment of different genotypes. The coefficient of genetic diversity in Jatropha relatively low criterion, whereas in the broad sense heritability values belonging to the low and moderate criteria. Highly significant genetic correlations between character growth occurs in plant height and stem diameter age 90 days after planting with r = 0.82.
