    Abstract

    Twenty-nine soybean genotypes were evaluated on the tidal swamp to obtain information of diversity response of soybean to the environment and to obtain adaptive genotypes that can be used to develop soybean genotypes for the land. This study was conducted from July to October 2014 in a type-B overflow tidal swamp at 2°38'40.8"S 104°45'10.0"E, Indonesia. The experiment was arranged in a randomized complete block design with 3 replications. Diverse genetic backgrounds, countries and climatic regions of the 29 soybean genotypes were responsible for the difference responses among the genotypes to the environment. All temperate and sub-tropical genotypes were able to produce seeds in the tropical type-B overflow tidal swamp. Adaptability based on seed yield resulted in 2 highly adaptive, 16 adaptive, 5 moderately adaptive and 6 non-adaptive genotypes. Adaptive and highly adaptive genotypes produced 1.56-2.58 t ha-1 of seeds. Karasumame (Naihou), a subtropical genotype, produced the highest seed yield which was 65% higher than Indonesian average soybean productivity and 225% higher than soybean productivity with non-saturated soil culture technology on the tidal swamp. This study concluded that the temperate and subtropical genotypes can be used as germplasm sources for soybean development in the tropical type-B overflow tidal swamp in Indonesia.
