Objective of this study was to compare the composite population, selection cycle 4, with some hybrid varieties. Three methods of stability analysis described by Francis and Kannenberg (1978), Finlay and Wilkindon (1963) and Eberhart and Russell (1966) were used. Seven varieties of sunflower were selected to study 11 characteristics. They were grown in 5 environments which represented as two different groups of significant G x E interactions. Each environment consisted of 4 replications arranged in a RCB design. The experiments were conducted from August 1990 to May 1991. The composite population had the highest stability and adaptation for all the 3 methods of analysis in all characteristics. The hybrid variety HYSUN 44 gave the highest yields in all environments (ranging from 120 to 439 kg/rai). The XF-452 variety showed the highest oil content (47 %). However, this was found only under the optimum environment. The HYSUN 33 variety gave the highest oil contents in all environments studied (ranging from 35 to 46 %).
