Jatropha ( Jatropha curcas L.) has been considered a promising species for biofuel production. However, jatropha is still considered undomesticated and breeding and genetic improvement programs are needed. In this context, germplasm collection and

impact on fruit growth, nut size, and kernel size in macadamia. According to Fattahi et al. (2014) , hazelnut nut weight was significantly affected by pollen source, whereas self-pollination reduced its nut and kernel trait values and increased the
