“…The effect of higher altitude on shortening dormancy was contrary to expectation because of delay in maturity and lower temperature accumulation. The importance of temperature during the growing season on dormancy has been reported earlier (van Ittersum 1992;Struik and Wiersema 1999;Visse-Mansiaux et al 2022). These findings partly agree with those of Visse-Mansiaux et al (2022) where variety explained the majority of the dormancy variability (60.3%) compared with other factors outside the tropics.…”

The study was conducted to determine the dormancy and physiological age characteristics of diverse potato genotypes as influenced by growing altitudes and seasons for future breeding strategies and optimal patterns of use. Dormancy and sprouting characteristics have an impact on tuber production, storability and seed quality for planting and ware for consumption and the market. This study presents the results of dormancy and physiological age measurements conducted on 47 potato genotypes grown at three altitudes with three replications at each location and in two contrasting growing seasons. The seed tubers were evaluated at low altitude under darkness on moist sand storage conditions to assess their dormancy release, number of sprouts, sprout weight, sprout length and percentage tuber weight loss. Results showed significant (p < 0.001) differences among genotypes, locations and seasons, and significant interactions between these factors for days to dormancy release, number of sprouts per tuber at dormancy release and at 45 days after dormancy release, length of longest sprout, weight loss percentage of unsprouted and sprouted tubers at dormancy release and at 45 days after dormancy release, respectively. There was a wide variation in time to dormancy release (54 to 136 days); most genotypes showed medium to long dormancy. Seed tubers grown at low altitude showed longer dormancy than those grown at higher altitudes, while genotypic differences in dormancy were very consistent across environments. Genotypes strongly differed in sprouting characteristics and weight loss. There were highly significant interactions between altitude and season for all variables assessed, except for the number of sprouts 45 days after dormancy release and the weight loss after sprouting. Generally, the genotypic effects were larger than those of altitude, season and the interaction effects for all variables evaluated. This paper will allow variety selection to optimize seed quality at planting and minimize storage losses while providing new targets for breeders.

“…In greenhouse trials, high temperatures during the growing season resulted in less dormancy and significantly shorter bud length (Bintje variety) (Visse-Mansiaux et al, 2022). Generally, tubers sprout easily when stored at 8-12 • C for 5-9 months (Murigi et al, 2021;Knowles et al, 2009).…”

“…The length of dormancy can be increased at low temperatures, whereas premature sprouting may begin at high temperatures (Sonnewald & Sonnewald, 2014). In greenhouse trials, high temperatures during the growing season resulted in less dormancy and significantly shorter bud length (Bintje variety) (Visse‐Mansiaux et al., 2022). Generally, tubers sprout easily when stored at 8–12°C for 5–9 months (Murigi et al., 2021; Knowles et al., 2009).…”

“…After harvest, the composition of the atmosphere during storage has a crucial impact on the duration of dormancy (Visse‐Mansiaux et al., 2022). Short durations of low oxygen or hypoxic conditions will rapidly break tuber dormancy, which is completely terminated in high CO 2 /O 2 (60% CO 2 /40% O 2 ), regardless of potato variety (Coleman, 1998).…”

The potato (Solanum tuberosum L.) is one of the most important food crops worldwide. Nevertheless, due to food safety concerns, substantial amounts of potatoes are not utilized, resulting in losses. Dormancy development is affected by potato variety, temperature, light, humidity, and so forth. Traditional and novel techniques to detect potato dormancy have been developed based on infrared spectroscopy, hyperspectral, and multispectral imaging systems in combination with simulation verification. This review describes the ability of novel approaches to address the uncertain hazardous issue and delay or inhibit potato dormancy incidence and development. Further, this review describes the role of carbohydrate metabolism and phytohormone regulation involved in potato dormancy, the mechanism of action to address dormancy, and challenges and recommendations moving forward. More work is needed to develop novel approaches toward addressing the problem of potato germination after harvest.
