Abstract

In order to identify important sources of germplasm that can be used in the hybridization process to obtain specific soybeans, 140 genotypes from Asia and Europe were analyzed. The chemical analyses were performed using spectrophotometry, besides the protein and oil content, one unsatured fatty acid (stearic) and three saturated fatty acids (oleic, linoleic, linolenic) were determinated. In general, a higher protein content has been identified in Asian material. In terms of fatty acid profile, similar results were obtained in both types of germplasm. ES Indicator and Suinong 35 varieties were identified with the highest values for protein content, while for fat content NS-L50101 genotype and Hefeng 54 varieties were noted. The strong negative relationship identified between protein and oil hightlights that it is difficult to create genotypes that are rich in both parameters. The regression exemplified for the fat and protein content shows that varieties with a protein content of more than 35% and fat higher than 21.75% have not been identified within the European or Asian biological material.
