The adaptability of shortseason soybean genotypes to varying longitudinal regions

Abstract

In the present paper, we 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. We therefore studied the adaptability of northern soybean genotypes (maturity groups 00-II) to two very distant locations with similar latitudes. One is Novi Sad, Serbia, where the varieties have been developed, while the other is Memuro on the island of Hokkaido in Japan. 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 favorable years. Plant height and seed weight were generally greater in Japan than in their country of origin due to higher rainfall in Japan. The coefficients of correlation among the traits varied depending on the environment.
