Abstract: The aim of this investigation was to identify suitable parental lines of vetch (Vicia sativa spp.) from Turkish and ICARDA germplasm, with appropriate morphological and phenological characters, for generating low %w w^{-1} \gamma-L-Glutamyl-\beta-cyano-L-alanine toxin cultivars, using infrared nitrile screening, dendrogram clustering, and Pearson correlations. A significant inverse relationship between seed-mass and %w w^{-1} \gamma-L-Glutamyl-\beta-cyano-L-alanine was observed in 13 semiprostrate lines of V. sativa. No corresponding seed-toxin, seed-mass relationship was observable in 41 lines of V. sativa subsp. sativa of erect habit. Accordingly, the possibilities for the incorporation of the low toxic compound in small-seeded semiprostrate V. sativa lines into larger seeded erect V. sativa lines, via a Mendelian crossing program, was investigated. The limitations to this conclusion are also discussed.
