Pollination and therefore fruit set in tomato ( Solanum lycopersicum ) is very sensitive to temperature. Parthenocarpy can be a useful trait breeding sustainable agriculture faced with global warming. Within collection of Moneymaker mutants monogenic recessive mutant high number was identified heat stress conditions named under hfs ). No morphological alterations vegetative reproductive organs were observed except the bigger size ovary. parthenocarpic, pollination not being required for set, although this absolute since it produced some under‐seeded fruit. When plants grown extreme temperatures (higher than 35°C), exhibits higher yield wild‐type (WT) due increased number. Another interesting characteristic its improved quality stress, exhibiting better sweetness/acidity balance WT. Interestingly, also tolerant combination salt positive effect on production both components yield, weight. The generation mostly seedless productivity make obtain new high‐yield lines adverse environmental conditions.
