How Physicochemical and Nutritional Traits of Potatoes May Vary Under Field Conditions Over Long Periods
The Institute of BioEconomics at the National Research Council (CNR-IBE) and the University of Catania, Italy, conducted a study to identify potato quality traits that are stable over time. The study analyzed the physicochemical and nutritional variation of these traits in different seasons and locations. This summary presents the results of the study.
In the vast field of agricultural research, the study of potatoes — one of the world’s most important non-grain staple crops — is gaining prominence due to its significant role in food security. The need to maintain the consistent quality of this important crop as global production escalates is paramount. This research delves into potato cultivation, specifically examining the physicochemical and nutritional properties of two early genotypes, Arizona and Vogue, over five consecutive growing seasons in the Mediterranean Basin, a major potato-producing area.

This study is characterized by a meticulous analysis of how temporal and spatial variations affect potato tuber quality. It aims to determine which potato quality traits stand the test of time, providing predictability under fluctuating climatic conditions. Conducted at two closely located sites with different soil characteristics, the study will investigate the resilience of specific potato traits to environmental variation.
From 2018 to 2022, the study will consistently monitor the physicochemical and nutritional attributes of tubers, revealing patterns of quality variability across seasons and locations. Despite this variability, traits such as pH, dry matter content, and starch content showed remarkable stability, suggesting them as reliable quality indicators over time. In contrast, variables such as total soluble solids, reducing sugars, citric acid, vitamin C, total phenolics, and antioxidant capacity varied significantly with changing climate, illustrating the complex relationship between genotype, environment, and potato quality.
The results highlight the critical influence of environmental conditions on potato tuber quality traits. The mild winters and warm, dry summers of the Mediterranean provide a unique setting to study how different seasons affect quality traits, highlighting the complexities and opportunities for maintaining potato quality.
By identifying stable quality traits, this study provides invaluable insights for agricultural scientists and farmers and has significant implications for the agricultural sector. It suggests directions for breeding programs to develop potato varieties with consistent quality traits, thereby increasing consumer and producer reliability. Furthermore, this research could influence establishing criteria for Protected Geographical Indications, thus protecting the reputation of regional potato varieties.
In conclusion, this study highlights the variable nature of potato quality traits under different environmental conditions. It emphasizes the importance of continued research to understand and counteract the effects of climate variability on crop quality. The consistent stability of pH, dry matter content, and starch content across seasons provides optimism for the future of potato production and indicates that achieving consistent crop quality is an achievable goal. This research not only advances our knowledge of potato physiology, but also sets the stage for future agricultural innovation and food security.
