بررسی پایداری عملکرد ارقام و لاین‌های سویا

In order to detect stable and high yielding cultivars for soybean cultivation areas, 17 cultivars and elite lines evaluated in form RCB design with 4 replication in six regions: Karaj, Khoram-abad, Moghan, Gorgan, Share-kord and Zaghan. Combined analysis of variance and satability analysis conducted by Eberhart and Rusell method. Result of this experiment showed: location , genotype and location × genotype interaction effects are significant in 1% level. Genotype 7 (Essex × Hamilton) is the most stable genotype and high general adaptability in across all locations. Genotype 13 (Linford) contains lower general adaptability in across all locations and Genotypes: No. 1 (DI74) and No.17 (L.17) contain specific adaptability for favorable regions
