Interpretive Summary: Soybean varieties are grouped according to the length of growing season. Some are short season, and some are long season, and then there are groups in between. These differ and move according to latitude, north to south zones. In this study, soybeans were tested in two widely different east to west zones, Serbia and Japan. Results showed that longer season varieties had higher yields in high yield environments. The soybean variety that performed best in Serbia did not perform best in Japan.

Technical Abstract: In the present paper, we studied the adaptability of northern soybean genotypes (maturity groups 00-II) to two very distant locations with similar latitudes. One is Novi Sad, Serbia and Montenegro, where the varieties have been developed, while the other is Memuro on the island of Hokkaido in Japan. We therefore wanted to determine the soybean genotypes’ adaptability to conditions different from those they are usually grown in—different in terms of climate, soil and agronomic practices. The results of the study showed there were differences among environments for all traits except plant height and seed weight. Although there was an overall positive correlation between the growth period and yield, we also found a difference in yield due to an interaction between environment and variety. The varieties with a longer growing season had higher average yields in favourable years. Plant height and seed weight were generally greater in Japan due to higher rainfall in Japan. The coefficients of correlation among the traits varied depending on the environment.
