Assessment of Tomato (Solanum lycopersicum) Landraces for Their Agronomic, Biochemical Characteristics and Resistance to Phytophthora infestans

Genetic diversity in crop plants is the conditio sine qua non for sustainable agriculture and long-term food security. Our research carried out morphological, agronomic, physico-chemical characterization resistance to late blight of 35 tomato landraces from seven countries. These have been approved appear Official Catalog Varieties. The International Plant Resources Institute (IPGRI) descriptors used describe tomato’s morphological agronomic characteristics. For characteristics, dry matter, pH, carotenoid content (lycopene, lutein, β-carotene)) were analyzed. Carotenoids monitored by high-performance liquid chromatography (HPLC). results showed that was very high. Three remarkable commercial value shown increased caused Phytophthora infestans, one most damaging diseases tomato. Also, six had a lycopene exceeding 100 µg/g sample. ranged between 0.769 (Marmande-FR 166) 140.328 mg kg−1 FW (Răscruci). landrace with highest β carotene PT 308 65.499 FW, while lowest values registered Marmande-FR 166 0.105 FW. present study provides essential information on qualities these their other content. are discussed light importance meeting preferences different producers consumers, choice suitable specific pedoclimatic conditions, supply pigment sources pharmaceutical industry. responds humanity’s great global challenges: preserving agricultural biodiversity, protecting environment identifying pest-resistant varieties, also consumer health finding important antioxidants.
