Sesame (Sesamum indicum L.) is a tropical oilseed found growing in the mid-altitude (<1700 m.a.s.l.) regions of Ethiopia. Recently, there has been an attempt by settler farmers from the Ethiopian plateau to expand sesame cultivation in the low altitude areas (<800 m.a.s.l.). A genotype-environment interaction study on sesame lines developed through progeny selection originating from a bulk of landraces was carried out at six environments in Ethiopia. The environments selected were believed to provide a wide variation in temperature (altitude), moisture and soil. The objective of the study was, therefore, to select a line or lines widely adaptable over these environments for variables seed yield, oil and protein content as well as fatty acid composition. Two statistical methods, namely, the regression model and the procedural approach of superiority measure were used to estimate line adaptability. Several lines were identified which were adapted over the six environments while others were specifically adapted to low- or high-yielding environments. Lines showing wide adaptation for one variable were not always widely adapted for others. In addition, the two parametric statistics used to analyze the data did not always agree for each variable.
