Comparison between “Dinamo” and “T-2012” lines.
**
Comparisons between each of the GM lines and their parental relatives (i.e., “Kuras” vs. “T-8003,” “Dinamo” vs. “T-2012”).

Comparison between the oil and amylose potato lines.
UN, N uptake efficiency; EN,yield, yield specific N efficiency; CN,yield, yield N concentration; NAE, N accumulation efficiency; N', plant mean N content during the entire growth period. Dry tuber biomass (DBTuber) at final harvest (H3) was used for the calculations.
