Comprehensive Understanding of Selecting Traits for Heat Tolerance during Vegetative and Reproductive Growth Stages in Tomato

Climate change is an important emerging issue worldwide; the surface temperature of earth anticipated to increase by 0.3 °C in every decade. This elevated causes adverse impact heat stress (HS) on vegetable crops; this has been considered as a crucial limiting factor for global food security well crop production. In tomato plants, HS also changes physiological, morphological, biochemical, and molecular responses during all vegetative reproductive growth stages, resulting poor fruit quality low yield. Thus, select genotypes develop cultivars with tolerance, feasible reliable screening strategies are required that can be adopted breeding programs both open-field greenhouse conditions. review, we discuss previous recent studies describing attempts screen heat-tolerant under have different regimes threshold temperatures, association tolerance physiological biochemical traits stages. addition, examined wide variety parameters evaluate tomato’s HS, including growth, such leaf parameters, plant height stem, terms flower number, set yield, pollen ovule development, thereby proposing development response high temperature.
