Abstract :Double crop agriculture is a great advantage for the coastal Mediterranean climate. Although a number of soybean varieties have been recommended for cultivation, the information on the stability for double cropping is lacking for the agro-climatic conditions of Mediterranean coastal zone. Ten high-yielding advanced soybean [Glycine max insert ignore into journalissuearticles values(L.); Merr] lines and four registered soybean varieties having maturity group III and IV insert ignore into journalissuearticles values(ARISOY, ATAEM7, BRAVO and NOVA); were evaluated for double cropping in different regions and years insert ignore into journalissuearticles values(2014, 2015 and 2016 in Izmir-Bornova, 2015 and 2016 in Antalya-Aksu);. The F test was first applied to check differences of the deviation variances from the zero. In addition, statistics of ecovalance insert ignore into journalissuearticles values(W i 2 ); and stability variance insert ignore into journalissuearticles values(σ i 2 );, estimating the contribution of a genotype to total Genotype x Environmental interaction insert ignore into journalissuearticles values(GxE);, were estimated. As a result of this research, two different conclusions were determined. If sufficient water is provide insert ignore into journalissuearticles values(500-700 mm); BATEM 306 and BATEM 317 lines can be grown, otherwise, the other two insert ignore into journalissuearticles values(BATEM 207 and BATEM 223); can be suitable to grow in the regional conditions.
