- Protein, oil and fatty acid composition ere determined on seed samples of Lupinus albus L cultivars gron in to different locations, Villafranca and Córdoba. Seeds planted in the latter location ere inoculated ith Rhizobium leguminosarum f lupini as soil pH as 7·5‐7·9. Locations clearly caused differences in both protein and oil contents. Interactions beteen localities and genotypes ere not significant. Environmental effects ere much greater than the genotypic factors except for oleic and linoleic acids. Both locality and genotype effects ere clearly significant for all fatty acids studied except for palmitic acid. A negative correlation as found beteen protein and oil content. Oil and oleic acid contents ere positively correlated to each other. Linoleic acid content seemed not to be correlated ith any other fatty acid except oleic. Linolenic acid content as also negatively correlated ith that of oleic acid. Covariance analysis shoed a strong positive genetic correlation beteen oil and oleic acid contents; the genetic correlation as higher than the environmental one. Oil content is strongly negatively correlated ith both linoleic and linolenic acid contents at the genotypic level.
