【 摘 要 】

Soybean is the most important legumes crop and source of protein for Indonesia society. The aim of the research was to evaluate the morpho-chemical characters of soybean genotypes across environments. A total of 16 soybean genotypes were evaluated in four different agro-ecosystems from February to May 2015. The experiment at each agro-ecosystem was arranged in a randomized block design with 16 treatments and four replicates. . The result showed that the morpho-chemical characters of 16 genotypes were significantly affected by genotype by environment interaction. The average of protein contents in four locations were 39.30%, 38.76%, 39.06%, and 38.14%, respectively; and the oil contents were 19.52%, 19.66%, 19.15%, and 20.54%, respectively. There was an indication that a higher protein content resulted in a lower oil content. The highest protein content was GRRR-12-15 (39.96%), and followed by Anjasmoro (39.84%) and GA-1-4 (39.46%). Genotypes with high oil content were GAAA-6-3 (21.36%), GAA-5-1 (20.72%), and GRRRR-19-7 (20.38%). A drier agro-ecosystem affected to the decrease in protein content. Stability analysis of protein content showed that GA-1-6 as the most stable genotype, followed by Anjasmoro and GA-1-4. Meanwhile, the most stable genotype for its oil content was Grobogan, and followed by GAAA-6-3 and GA-1-6. The high yield productivities were showed by GAAA-6-7 (3.06 t/ha), GA-1-4-2 (2.91 t/ha), and GA-1-4 (2.82 t/ha). The two top yielding genotypes, GAAA-6-7 and GA-1-4, were showed specific adaption, hence they can be recommended to be developed at relatively dry environment to obtain high yield, protein and oil contents.
