Evaluation of Advanced Backcrosses of Eggplant with Solanum elaeagnifolium Introgressions under Low N Conditions

Selection and breeding of eggplant (Solanum melongena) materials with good performance under low nitrogen (N) fertilization inputs is a major objective to reduce environmental degradation, risks for human health, production costs. Solanum elaeagnifolium, an wild relative, potential source variation introgression in eggplant. We evaluated 24 plant, fruit, composition traits set genotyped advanced backcrosses (BC2 BC3) S. elaeagnifolium introgressions N conditions. Significant differences were found between the two parents most traits, wide phenotypic diversity was observed backcrosses, some individuals much higher yield, use efficiency (NUE), phenolics content than melongena parent. In general, lower proportion genome introgressed general resemblance melongena. Putative QTLs detected stem diameter (pd4), presence prickles (ps6), leaf (pl6) fruit calyx (pc6), width (fw7), chlorogenic acid (cg5), total phenolic peaks area (ph6), peak (ca1), acids pattern (cp1). Our results reveal that has great interest breeding, particularly adaptation These can potentially contribute development improved varieties more sustainable agriculture.
