Survey of the Genus Lycopersicon for Variability in α-Tomatine Content1

Abstract
Twenty-seven accessions from 6 species of the genus Lycopersicon and 1 accession of Solanum pennellii were surveyed for content of the glycoalkaloid, α-to-matine. Significant variation in alkaloid content was found to exist among the accessions. L. esculentum cultivars were found to contain much lower concentrations of α-tomatine than accessions of L. esculentum var. cerasiforme, L. pimpinellifolium, and the L. peruvianum accession, LA 462.
