Abstract excerpt

BACKGROUND: Drought stress is a major constraint limiting tomato (Solanum lycopersicum L.) productivity worldwide. In vitro selection using polyethylene glycol (PEG)-induced osmotic stress provides a controlled approach for identifying stress-responsive genotypes. METHODS: This study aimed to select local tomato varieties using an in vitro selection system based on PEG 6000-induced osmotic stress (0-8%). Callus...
