Starch and sugar content of potato tubers are quantitative traits, which are models for the candidate gene approach for identifying the molecular basis of quantitative trait loci (QTL) in noninbred plants. Starch and sugar content are also important for the quality of processed products such as potato chips and French fries. A high content of the reducing sugars glucose and fructose results in ...

In addition to common vegetative multiplication, potato crop can be reproduced by true potato seed (TPS). Only the limited number of pests and diseases, which are the most important causes of a decrease in potato production, can be transmitted by true potato seed. Hence, to evaluate the potential of true potato seed in comparison to potato seed tuber and mini tuber, an experiment was conducted ...
