Drought and salinity are considered the most challenging environmental constraints limiting crop productivity globally. Furthermore, the effect of global warming and climate changes forces plants in open cultivation to endure more severe climatic conditions.
While in past decades breeding programs have largely concentrated on developing cultivars with high yield potential under non-stress conditions, a decrease of natural resources and arable lands, have forced breeders to concentrate on increased crop production in stressful agricultural environments.
In contrast to related wild species of tomato, cultivated tomato has a limited variation to abiotic stress tolerance. Therefore, new genetic variation is urgently needed to support introgression of agronomically important traits between Solanaceous species.
The project aims to:
- identify genomic organization of economically important traits including drought and salt stress tolerance, and pathogen resistances within cultivated and related wild species of Solanum and Capsicum crops;
- reveal synteny between donor species and recipient crops.
