Adaptability and stability of new soybean cultivars under double cropped conditions of Turkey

摘要

A two-year field study was conducted at six distinct locations of Turkey, Adana, Antalya, and Diyarbak?r to determine yield performance and yield stability of new soybean cultivar candidates for double cropping systems. The standard cultivars were A 3935, Umut 2002, Nazl?can and Turksoy. The newly developed soybean cultivars?Ataem 6, Ataem 7, 1530, 527, SxW11, SxW-7, SxW-3 and Nova?were tested over five locations in the Mediterranean and Southeastern Anatolia regions for double cropping systems.Experimental design was randomized complete block with three replications. Comparison of cultivar means in the?double cropping system, A 3935 had the highest seed yield with 3313 kg/ha followed by Umut 2002, Nazlican and Turksoy. According to results obtained, specially the bi?value, cultivars?A3935,SxW-7, and Ataem 7 were found more stable cultivars for the double?cropping systems.
