Assessment of genetic variability and multivariate analysis for yield and quality improvement in an interspecific F₂ population of tomato (Solanum lycopersicum L.) under high-temperature stress
Heat stress is one of the major abiotic constraints limiting the productivity of tomato, especially at the reproductive stage. An interspecific F2 population developed from the cross PKM 1 × Solanum pimpinellifolium L. was evaluated at the Vegetable Research Station, Palur, Tamil Nadu, India, to identify important trai...
