Fruit Composition of Eggplant Lines with Introgressions from the Wild Relative S. incanum: Interest for Breeding and Safety for Consumption

The wild species Solanum incanum has been used as a donor parent for the development of set eggplant introgression lines (ILs), which are interest breeding stress tolerances and relevant morpho-agronomic traits but could also be useful fruit quality, due to generally higher content in health-promoting compounds S. incanum. use ILs with introgressions from requires ensuring that glycoalkaloids levels below safety limits. We evaluated 25 composition traits, including proximate composition, sugars, acids, phenolics, glycoalkaloids, minerals 16 incanum, both parents F1, grown under two environments (open field screenhouse). results demonstrated were significantly different regarding most traits. Large variation was found among all analyzed strong influence environment accounted 17 out evaluated. Although produced fruits high showed mean values total currently accepted limit human consumption (200 mg kg−1 fresh weight). Overall, safe consumption, nutritional functional quality similar recipient parent. Furthermore, six putative QTLs detected spread over chromosomes 3 crude protein, 5 malic 7 chlorogenic acid solamargine, potential candidate genes spotted them, provide new information breeding.
