A randomized complete block design with fifteen genotypes in three ecoregions (dry Caribbean, Inter-Andean Valley and Orinoquia) was established. The AMMI model and its biplot graph were used to determine phenotypic stability of the fruit yield and with the oil yield the net benefit and the benefit-cost ratio were determined. <strong><span class="CharOverride-9">Results.</span></strong> In two of the three ecoregions used; dry Caribbean and Inter-Andean Valley, <span class="CharOverride-10">J. curcas</span> presented an accumulated fruit yield of 3.6 t ha<span class="CharOverride-6">-1 </span>and 6.7 t ha<span class="CharOverride-6">-1</span>, respectively; in the Orinoquia region the yield was less than 0.1 t ha<span class="CharOverride-6">-1</span>. The cost of a liter of <span class="CharOverride-10">J. curcas</span> oil was US$1.07 for Albania (dry Caribbean) and US$1.24 for Espinal (Inter-Andean Valley), higher than that of African palm oil (<span class="CharOverride-10">Elaeis guineensis</span>) of US$0.89. <strong><span class="CharOverride-9">Conclusion. </span></strong>The fifteen<span class="CharOverride-10"> J. curcas </span>genotypes used in this study showed the best productive performance in Albania (dry Caribbean) and Espinal (Inter-Andean Valley), and the CJC3 genotype was the one with the best fruits and oil production.</p> ER -
