OIL CONTENT AND FATTY ACID PROFILE IN SEEDS OF POLISH BREEDING LINES AND CULTIVARS OF LEGUMES
Journal Title: Acta Scientiarum Polonorum – Agricultura - Year 2016, Vol 15, Issue 2
Abstract
Current studies aimed at replacing soya bean meal with other legumes should take into consideration not only protein content and quality, but also the content and quality of oil. The aim of this study was to assess the Polish breeding lines and cultivars of yellow, blue and white lupine, faba bean as well as hairy and common vetch with regard to their raw oil (crude fat) content and fatty acid profile. The study involved 9 lines and cultivars of yellow lupine and 8 of blue lupine, 2 cultivars of white lupine, 2 cultivars of faba bean, 1 cultivar of hairy vetch and 1 cultivar of common vetch. The content of oil in seeds of the yellow lupine lines and cultivars was within the range 5.1-6.6%, blue lupine 6.2-6.9%, white lupine 9.3-10.6%, faba bean 1.7-1.8%, hairy vetch 1.2% and common vetch 1.1%. Linoleic acid was the main fatty acid in the faba bean, hairy and common vetch and in most of the yellow lupine genotypes oils. Oleic acid dominated in the white lupine oil, whereas in the blue lupine oil linoleic and oleic acids occurred usually in similar quantities. The highest content of α-linolenic acid was in the two vetch species (8.4-8.5%), the next highest in white lupine (6.8-7.6%) and yellow lupine (5.4- -9.0%) with the lowest in faba bean (3.2-5.8%) and blue lupine (3.2-5.2%). Yellow lupine genotypes were more differentiated in respect of their oil content, α-linolenic acid and the value of the n-6/n-3 acids ratio than were the blue lupine genotypes.
