| Summary: | ABSTRACT Storage can reduce seed germination potential and viability, especially in high-lipid species, such as peanuts. This study evaluated the physiological quality of stored peanut seeds from different lineages under long-term storage conditions. The experiment followed a completely randomized design, including ten peanut lines, comprising four commercial cultivars and six genotypes from the Peanut Improvement Program (PMA) of EMBRAPA, with five replications. Seeds were evaluated at two time points: before storage (time zero) and after 12 months of storage. Assessments included moisture content, seed germination percentage, seedling emergence, and seedling development. Data were analyzed using analysis of variance (ANOVA), and means were compared using Tukey's test (p < 0.05). Results indicated that storage time reduced the physiological potential of peanut seeds. However, seeds from lines 5, 10, 4, and 9 maintained viabilities over 12 months, whereas lineage 8 exhibited low germination and seedling emergence after storage. The substrate emergence test proved to be a more sensitive indicator of physiological seed quality among peanut lines. |
