CHARACTERIZATION OF THE INDUSTRIAL QUALITY OF SEED SOYBEAN: THROUGH MULTIDIMENSIONAL ANALYSIS

Abstract

Little information is available in Mexico relatad to quality characteristics of soybean (Glycine max L.) seeds of different genotypes grown in diverse environments. Therefore seeds from soybean genotypes grown in Tapachula and Mazatan, Chis.; Ebano, S.L.P.; Huastecas, Tam.; and Valles Centrales, Oax., were evaluated at the INIFAP Oil Seeds Laboratory. Oil, protein and crude fiber mean
contents were 24, 36 and 6%, reapectively; oleic and linoleic acids levels ranged from 16 to 37%, and 40 to 63%, respectivaly. Linolenic acid mean content (7%) was low, which insure a good oil stability during storage. Seed weight and oil values showed a 0.59•• correlation; outstanding genotypes for these two variables were H-79-1030, H-90-0918 and Mineira, when they were grown in
Mazatan, Chiapas; Tropicana, UFV-1 and H-80-0892 were the best genotypes for protein, lisine and tryptophan; Ebano, Tam. was the location where the highest protein and aminoacid contents were found. On the other hand, linoleic acid synthesis was promoted at Huastecas, and genotypes F-76-7233-1 , H-80-0892 and H-78-0319 had the highest contents. In this study it was corroborated the value of multivariate analysis to integrate locations and/or groups of genotypes according to common quality characters.
