Implication

Experimental study demonstrates that wild Solanum incanum introgressions improve water stress tolerance in eggplant, indicating strong potential for breeding climate-resilient crops.

Key Points

To evaluate drought tolerance and agronomic performance in eggplant introgression lines carrying genomic segments from the wild relative Solanum incanum under restricted irrigation.
Assessed nine Solanum melongena introgression lines representing 71.6% of the donor wild parent S. incanum genome.
Grew plants to the five true leaves stage and subjected them to either 100% field capacity (control) or 30% field capacity (water stress) for 14 days to measure growth and physiological parameters.
Water deficit reduced vegetative growth and increased physiological stress markers, including proline and malondialdehyde, with most introgression lines exhibiting lower biomass than the cultivated control.
Wild alleles at two quantitative trait loci, dwt8 (stem dry weight) and dwr6% (root dry weight), significantly enhanced tolerance under water-limited conditions.
Specific S. incanum alleles positively regulated key drought-response traits, including leaf water content (lwc12%), water use efficiency (wue1%), and chlorophyll content (chl2 and chl8%).
