This article presents the scientific and theoretical basis for the comprehensive evaluation of tomato (Solanum lycopersicum L.) genotypes under protected cultivation according to phenological and biometric traits, fruit-quality indicators, and biofortification potential. The research direction is focused on assessing gene-bank accessions and hybrids for Fe, Zn, Ca, Se, lycopene, beta-carotene, ascorbic acid, and antioxidant activity; identifying donor genotypes with high nutritional value; and developing a breeding-genetic model suitable for protected cultivation. The article substantiates the scientific importance of creating biofortified tomato varieties through the integrated use of phenological, morphological, biometric, biochemical, mineral, and statistical analyses.
