“…There was a strong cultivar and storage temperature interaction: Festien and Innovator stored at 17 °C, 10 °C, and in some cases 7 °C passed their maximum, while Agria and Lady Claire did so only when stored at 17 °C (Fig. S1, Zou et al 2024).…”

“…The study was conducted over three cycles (2019/2020, 2020/2021, 2021/2022), each consisting of a seed production season, a storage season, and a crop production (field) season. Seed performance during the storage seasons has been analysed and reported by Zou et al (2024). The present paper focuses specifically on the crop production seasons, during which in total eight field experiments were carried out: two in Cycle 1 and three in Cycles 2 and 3.…”

“…In Cycle 3, the storage temperatures were 4, 10, and 17 °C to create a wider range. Storage T-sums of each temperature treatment across cycles are listed in Table 2 after "Storage" (for details, see Zou et al 2024). During the storage periods of the three cycles, no instances of rotten tubers, moulded tubers, visual symptoms of diseases, or formation of 'little potatoes' were observed.…”

“…T-sum is the accumulated daily temperature (mean hourly air temperature above a base temperature of 0 °C). Values shown in parentheses were estimated based on the average daily temperature in the corresponding periods in other cycles (for Cycle 1) or at other sites (for Cycle 3) Sprouting behaviours during storage and in sprouting tests were reported by Zou et al (2024). At the end of each storage season, all seed tubers had broken endo-dormancy.…”

“…Different storage temperatures were applied as the sole treatment to create variations in physiological age. Our previous work has quantified the ageing process of seed tubers during storage through sprouting behaviour analysis, where storage temperatures induced varying sprouting patterns in cultivars characterised by different rates of ageing (Zou et al 2024). In this study, these seed tubers were planted at three sites and during three cycles, and crop performance was phenotyped in great detail, including emergence, number of stems, canopy development, number of tubers, tuber yield, and quality (including tuber size distribution and tuber dry matter concentration).…”

The physiological age of potato seed tubers influences the subsequent field performance of the crop, conditioning its growth and development. This study investigates the effects of the physiological age of seed tubers on the field performance of four contrasting, currently widely grown cultivars (Agria, Festien, Innovator, Lady Claire) across three sites in the Netherlands over 3 years (Cycles 1—3). Seed tubers were produced annually at a single site under uniform conditions, with variations in physiological age induced by applying different storage temperatures (4, 7, 10, and/or 17 °C). Our previous study revealed varying effects of storage temperature on sprouting behaviour among cultivars, suggesting different rates of ageing. After completing the storage season, in the current study these seed tubers were planted in the field and subsequent crop performance was thoroughly phenotyped. Cultivar-specific effects of storage temperature were evident during early growth stages and when seed tubers were stored at 17 °C in Cycle 3. However, within the storage temperature range of 4 to 10 °C, the influence of storage temperatures was small or inconsistent. Overall, effects on canopy cover, stem and tuber number, yield and quality, and tuber yield explanatory variables were limited. The outcomes suggest that while very high storage temperatures should be avoided in regions with long crop cycles, stringent cold storage regimes are unnecessary to achieve optimal growth vigour in potato seed tubers of the studied cultivars in a temperate climate.

For potato, diploid hybrid breeding is a novel breeding technique that speeds up the development of new varieties. A consequence of hybrid breeding is the introduction of hybrid true potato seeds as starting material. From these seeds, seedling tubers can be produced in one field season, to use as starting material for a seed or a ware crop in the following year. For breeding purposes as well as for seed crop and ware crop production, it is essential to produce seedling tubers of high quality. The production of seedling tubers is a new step in the potato production chain; therefore, we investigated the effect of tuber quality traits on plant development and yield. With similar seedling tuber weight, more eyes per seedling tuber led to more stems per plant. This was compensated by a lower number of tubers per stem resulting in an equal total tuber number and weight per plant at the end of the growing season. A higher seedling tuber weight led to a higher soil cover in the field. Hybrid potato plants grown from larger seedling tubers produced a greater total tuber weight per plant than plants grown from smaller tubers, while number of eyes and stems per tuber had no effect on final yield when using equal seedling tuber weight.
