Determination of Stability and Genotype X Environment Interactions of Some Agronomic Properties in the Different Soybean (Glycine Max. (L) Merrill) Cultivars
Özet
It was aimed to determine the genotype x environment interactions and stability of seed yield and some agronomic characteristics of soybean in different ecogeographical locations of Turkey. In this study, field experiments were conducted at 8 locations in Turkey (Bafra, Carsamba, Turhal, Erbaa, Gokhoyuk, Suluova, Kabali, Boyabat) during two years. The eight soybean cultivars (Flint, Apollo, Savoy, Amsoy 71, Macon, Ap2292, SA88, A3127) were used in this study. The effect of genotype (G), environment (E) and GxE interactions on pod number per plant, plant height, seed yield and 1000-seed weight were found significantly (p<0.01). Among the experiment locations, the pod number per plant ranged between 87.34 and 33.87 units; plant height between 100.41 and 68.71 cm; seed yield between 379.49 and 211.85 kg dad; 1000-seed weight between 210.06 and 133.66 g. The highest seed yield was obtained from Flint cultivar. Besides, Flint and Apollo cultivars were good performance in all environments for seed yield. SA88 cultivar in terms of pod number per plant, and Macon cultivar in terms of plant height was found to be stable in all environments. A stable cultivar for seed yield could not be found among the cultivars.
