- Observation The three backcross populations had wild relative genome coverage of 58.8%, 46.3%, and 99.2%, respectively.
- Intervention effect Low nitrogen reduced chlorophyll content traits in eggplant parents.
- Intervention effect Low nitrogen reduced aerial biomass and stem diameter in eggplant parents.
- Intervention effect Low nitrogen increased nitrogen use efficiency, uptake efficiency and utilization efficiency in eggplant parents.
- Observation Each backcross set had high phenotypic variation under low nitrogen, with some transgressive individuals.
- Observation Recurrent parent genome recovery in the backcrosses was variable but high.
- Method / resource Genotyping identified 16 quantitative trait loci.
- Observation Introgressed QTL alleles showed different allelic effects.
- Observation Candidate genes were found in QTL regions associated with growth, yield, fruit size and nitrogen efficiency.
