AbstractAdaptability of Plant species (crops) cultivars could be characterized using their performance via certain trait over given environment. Thus, multi methods were applied to investigate this adaptability ofv10 cultiraj from caraway. Therefore, ternary plot conducted out at first time in middleeast especially in Iraq to test ten cultivars of caraway adaptation via carvone% and its yield (kg.ha-1) across two locations, Fallujah and Ramadi for two successive seasons, 2011/2012 and 2012/2013 to become four environments. AMMI biplot laid out to support ternary plot. Past software used to construct ternary plot graphs. Also cropstat 7.2 software to extract cultivars and envirronments biplots. Results reveald that ternary plot method sorted cutlivars into three categories relied on carvone% viz non-adaptable cultivars included G4. While the other two categories involved cultivars those had two behavors once adaptable again non-adaptable that located on straight line between Ibottom and Itop the last one included cultivars that once behad near to Itop again to Imiddle that located on mid of triangle. According to carvone yield, G3 is semi-adaptable across four environments, whereas, AMMI Biplot precisely showed that G3 and G7 were most adaptable over most evnvironments. Thus, G7 was the most adaptable genotype.
