Resumen:
The ratio of oleic to linoleic acids (O/L) and the tocopherol content are important features in determining
peanut (Arachis hypogaea) seed shelf life. Soluble carbohydrates are known to be important precursors
in roasted peanut flavor. The chemical qualities of Argentine grain are different from those of other
countries, but no previous studies that associate grain quality and environmental parameters have
been performed. Relationships were determined between O/L, tocopherol and sugar contents, and
variations in temperature and rainfall during the grain filling period of Florman INTA peanuts. Dry
seed yield was used as another explanatory variable. Multiple regression procedure gave mean
temperature (positive coefficient) and total precipitation (negative coefficient) as the explanatory
variables for variations in O/L. Total precipitation and dry seed yield (both negative coefficients) were
found to be predictor variables for tocopherol and sugar contents. Total precipitation was an
explanatory variable included in all of the linear regression models obtained in this study.(O/L) and the tocopherol content are important features in determining
