The rapidly growing global population emphasises the need for high-yielding, sustainable, yet nutritious food crops, which produce consistent yields under varying agricultural conditions. There are various critical research hypotheses that propose solutions for this scenario with some of the main focus areas being crop management and precision farm...

... Overall, the great variability found over the years in nutritional traits, contrary to the relative stability found in physicochemical traits, is not surprising, since, as is known, the formation of potato organic nutrients is influenced by the interaction of multiple agricultural meteorological factors. 24,[56][57] These factors include sunshine duration, temperature, water resources, atmospheric resources and wind resources, which collectively influence the growth and development of potato plants and the subsequent formation of nutrients in potato tubers. Sunshine duration, for instance, plays a crucial role in regulating the photosynthesis of potato plants and affecting enzyme activities in potato tubers. ...
BACKGROUND
Potato is the most important non‐grain crop worldwide, whose quality characteristics are always affected by temporal and spatial variability. Knowledge of the performance consistency of quality characteristics over long periods could prove very important to identify which quality traits are less variable over time, and therefore provide greater guarantees of stability. In this research, variations in physicochemical and nutritional traits of tubers over five consecutive growing seasons of two potato genotypes (Arizona and Vogue) were monitored in two locations.
RESULTS
Although qualitative performances of genotypes fluctuated across the seasons in both locations, two physicochemical traits (pH and dry matter content) and starch content showed less variability throughout the five seasons compared to total soluble solids and most of the nutritional traits (namely reducing sugars, citric acid, vitamin C, total phenolics and antioxidant capacity), which were considerably influenced by weather conditions.
CONCLUSION
The results suggest that pH, dry matter content and starch content traits could be used advantageously in studies of temporal stability in potatoes. This approach could prove useful in providing scientific support for the setup of potato protected geographical identifications. © 2024 Society of Chemical Industry.
