Dataset for: At least ten advanced clones of the LBHTXLTVR population selected with low glycoalkaloid content in contrasting environments. In addition to high levels of late blight resistance, high tuber yield, heat tolerance, adapted to midland and highland in San Ramon.

Total glycoalkaloids analysis was performed using the method described by Burgos et al. (2014) in which the extraction of glycoalkaloids was executed using methanol and chloroform prior to concentration at 60 ° C in a rotary evaporator. The extract was transferred to 2% acetic acid solution and then purified using ammonium hydroxide at 85 ° C and ultracentrifugation at 27,000 rpm. The pellet was reacted with 85% orthophosphoric acid and read at 408 nm in a spectrophotometer.

The determination of total glycoalkaloids was performed against a standard curve of α-chaconine as a reference. This parameter was used as a criterion to select the clones to be further evaluated in the next season. Only clones with a total glycoalkaloid concentration below the safety limit for human consumption (20 mg / 100 g fresh weight) were selected.
