“…Some of the field sites that reported heat stress on potatoes are San Ramón, Peru, and Lavras, Brazil. San Ramón frequently experiences heat stress ( Khan et al., 2015 ; Benavides et al., 2017 ; Raymundo et al., 2018 ; Muñoa et al., 2022 ) with an average day/night temperature of 28/23°C ( Benavides et al., 2017 ) but fluctuating between 16 to 36°C ( Muñoa et al., 2022 ). In Lavras, Brazil, the mean maximum and minimum temperatures are 28.5 and 16.5°C, respectively ( Lambert et al., 2006 ).…”

“…Of the 156 countries worldwide that plant potatoes ( FAO, 2019 ), heat stress is reported in various places, including tropical highlands. Lavras in Brazil ( Lambert et al., 2006 ); San Ramón in Peru ( Khan et al., 2015 ; Benavides et al., 2017 ; Raymundo et al., 2018 ; Muñoa et al., 2022 ); Jalandhar in India ( Bhardwaj et al., 2022 ), Western Australia in Australia ( Obiero et al., 2022 ) are considered heat stress sites for the selection of heat-tolerant potatoes. Some unexpected areas, like Ontario, Canada, have also been reported to experience heat during the potato growing season.…”

In recent years, heat stress has affected potato production more frequently, resulting in lower marketable yields and reduced tuber quality. In order to develop heat-tolerant potatoes, it is necessary to select under heat-stress conditions and consider traits affected by heat stress. The Texas A&M Potato Breeding Program has selected potatoes under high-temperature stress for several decades. Ten potato cultivars, representing heat tolerant and sensitive clones based on past performance in Texas, were included in field trials for three years at the two main locations used by the Texas Breeding Program (Dalhart and Springlake, TX) to assess if the Texas field locations are suitable for heat tolerance screening. Both locations were confirmed as appropriate for heat stress screening. However, Springlake was a more stressful location since it had significantly lower yields of marketable tubers and increased percentages of tuber defects. Planting time did not have a significant effect at the most stressful location. The same ten potato clones were included in greenhouse experiments with contrasting temperatures (normal versus heat stress). There was confirmation that heat stress conditions resulted in significantly lower marketable yields, specific gravity, dormancy, and significantly higher percentages of tuber defects; however, significant differences existed between potato clones. Under heat stress conditions, Russet Burbank had a high percent of tubers with external defects, whereas Atlantic showed the highest percentage of internal defects (mainly internal heat necrosis). Vanguard Russet produced the highest marketable yield while maintaining a low percentage of external and internal defects. Russet Burbank and Atlantic were heat-sensitive controls for external and internal tuber defects, respectively. In contrast, Vanguard Russet can be used as a reliable heat-tolerant control. Including appropriate controls in heat stress studies will help identify clones with heat tolerance.

“…Potato tubers in targeted tropical areas tend to add in the glycoalkaloid concentration due to high temperature. These toxic substances cause bitterness and have harmful effects on human health (Friedman 2006;Gastelo et al 2017). A glycoalkaloid level less than 7 mg/100 g is considered safe in warmer area than the acceptable level of 20 mg/100 g in traditional areas (van Dam 2002; Gastelo et al 2017).…”

The process to develop potato cultivars is complex and lengthy due to numerous reasons, viz., tetrasomic inheritance with heterozygous nature, large number of phenotypic recurrent selections, low efficiency of selections in early generations, slow multiplication rate of selected clones, and others. In Southeast Asia, varieties are primarily developed by public sector having poor seed multiplication facilities, and the complexity is further aggravated by the presence of few commercial seed multipliers. To speed up the breeding and selection processes and ensure the adoption of developed varieties by strengthening the seed value chain, a public–private partnership has been established between International Potato Center and HZPC, a leading private potato seed company. The adopted integrated breeding approach is a blend of modern and traditional breeding techniques involving shuttle breeding and stringent selection of disease-resistant cultivars through marker-assisted selection at early stage, followed by parallel evaluation in several environments and rapid disease-free multiplication of the elite material. This study simultaneously addresses the issues related to the extensive and complex variety registration process in the region by initiating discussion with the local authorities. The collaboration is likely to set norms for licensing and benefit-sharing between public and private partners in future alliances.

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.
