This study assessed the feasibility of providing a regular supply of locally produced potatoes during landlocked winter months in Ladakh region. Potato tubers were stored (January–May) in semi-underground stores where conditions were between 0.2–13.6 °C and 87–96% relative humidity. Periodical sample analysis was carried out on sensory attributes and the physicochemical attributes firmness, sprouting, pulp temperature, total soluble solutes, sugar level, vitamin B6, dry matter, weight loss and CIPC residue level, to evaluate the quality of the stored potatoes. Pearson’s correlation analysis measured the relationship between various physicochemical attributes that helped improve understanding of potato variability. CIPC residue concentration was within the recommended limit of 30 mg/kg tuber in peeled and unpeeled tubers ranging from 0.02 to 0.12 mg/kg and 0.04 to 3.90 mg/kg, respectively. Tubers stored during extreme winter conditions showed the highest level of total sugar 927 ± 8.54 mg/100 g after 5 months of storage. Vitamin B6 was 0.276 mg/100 g in CIPC treated potato and 0.190 mg/100 g in non-treated potato which is approximately 15% of recommended daily vitamin B6 intake. Based on the results of this study, potatoes stored in zero energy–based semi-underground stores were in good quality after a period of 5 months and suitable for consumption.

这项研究评估了在拉达克地区内陆冬季，定期提供本地生产的马铃薯的可行性。马铃薯块茎（1月至5月）存储在条件介于0.2-13.6°C和87-96％相对湿度之间的半地下存储中。定期对感官属性和理化属性（硬度，发芽，果肉温度，总可溶性溶质，糖水平，维生素B6，干物质，失重和CIPC残留物水平）进行理化分析，以评估马铃薯的品质。皮尔森的相关分析测量了各种物理化学属性之间的关系，这些属性有助于增进对马铃薯变异性的了解。在去皮和未去皮的块茎中，CIPC残留物浓度在建议的30 mg / kg块茎极限内，范围为0.02至0。分别为12 mg / kg和0.04至3.90 mg / kg。在极端冬季条件下储存的块茎在储存5个月后显示出最高的总糖含量927±8.54 mg / 100 g。CIPC处理的马铃薯中的维生素B6为0.276 mg / 100 g，未经处理的马铃薯中的维生素B6为0.190 mg / 100 g，约占建议每日维生素B6摄入量的15％。根据这项研究的结果，在零能耗的半地下仓库中存储的马铃薯经过5个月的使用后质量良好，可以食用。
