“…The sub-theme focused on healthier, sustainable diets, with one keynote presenting findings on the bioavailability study of high-iron potatoes (Burgos et al, 2023), whose 29% absorption rate of iron is higher than that for high-iron millet and high-iron beans. The other keynote focused on longitudinal findings from an integrated orange-fleshed sweetpotatobehavior change intervention in southern Ethiopia, which examined the added value of using a "Healthy Baby Toolkit."…”

“…While iron concentrations in potato are lower than those reported for cereals and legumes, potato iron bioavailability has proved to be significantly higher due to the presence of high levels of vitamin C, which promotes iron absorption in the human body, combined with low levels of phytic acid, an inhibitor of iron and zinc absorption. Yellow-fleshed potato bred at CIP for high Fe content had a remarkably high level of bioavailable iron ranging from 16% in Peruvian women with moderate iron stores (Burgos et al 2023 ) to 29% in Peruvian women with low iron stores (Jongstra et al 2020 ). Sweetpotato iron bioavailability has been reported between 5 and 8% in women from Malawi (Jongstra et al 2020 ).…”

Root and tuber crop breeding is at the front and center of CIP’s science program, which seeks to develop and disseminate sustainable agri-food technologies, information and practices to serve objectives including poverty alleviation, income generation, food security and the sustainable use of natural resources. CIP was established in 1971 in Peru, which is part of potato’s center of origin and diversity, with an initial mandate on potato and expanding to include sweetpotato in 1986. Potato and sweetpotato are among the top 10 most consumed food staples globally and provide some of the most affordable sources of energy and vital nutrients. Sweetpotato plays a key role in securing food for many households in Africa and South Asia, while potato is important worldwide. Both crops grow in a range of conditions with relatively few inputs and simple agronomic techniques. Potato is adapted to the cooler environments, while sweetpotato grows well in hot climates, and hence, the two crops complement each other. Germplasm enhancement (pre-breeding), the development of new varieties and building capacity for breeding and variety testing in changing climates with emphasis on adaptation, resistance, nutritional quality and resource-use efficiency are CIP’s central activities with significant benefits to the poor. Investments in potato and sweetpotato breeding and allied disciplines at CIP have resulted in the release of many varieties some of which have had documented impact in the release countries. Partnership with diverse types of organizations has been key to the centers way of working toward improving livelihoods through crop production in the global South.

“…Fe found in potato is very well absorbed by the human body. According to recent Fe absorption studies in women using stable isotopes, the Fe from yellow-fleshed biofortified potatoes has a remarkably high absorption (14–29%); this is greater than that reported for other biofortified crops such as pearl millet and beans (4 to 8%, respectively) [ 10 , 11 ]. In another related research, the higher bioavailability of minerals in potato tuber and other major food crops is reported owing to the high concentrations of promoter chemicals such as ascorbic acid that promote micronutrient absorption by the body [ 12 ] and low level of inhibitor chemicals [ 13 ].…”

Malnutrition is one of the global issues of public health concern, and iron and zinc deficiencies are at the top of the list. Iron deficiency affects more than 2 billion people in the world and is a major cause of anemia. Potato has the potential to be an important source of iron and zinc. This study assessed the nature and magnitude of genetic variability in Fe and Zn concentrations, tuber yield, and quality traits among biofortified tetraploid potato clones and their relationships through correlation and path analysis. A total of 45 potato genotypes, including the variety Gudanie, were grown in field trials in a 9 × 5 alpha lattice design with three replications. Significant differences in mineral, tuber quality, and yield traits were observed among the genotypes, and high broad-sense heritability was obtained for most traits, suggesting that progress through breeding can be achieved. However, negative correlations and direct effects on most of the traits with Fe and Zn contents are found both at genotypic and phenotypic levels. Therefore, attaining simultaneous genetic gain for yield and enhanced Fe and Zn concentrations will be challenging. Cluster analysis assembled them into five groups. Cluster II contained the most prominent genotypes, having better mean values compared to all other genotypes for micronutrient traits, viz., Fe (23.80 mg kg−1) and Zn (17.07 mg kg−1). The results of this study confirm the presence of sufficient genetic variation for iron and zinc mineral concentration and the possibility to make significant progress through breeding.
