Optimizing the accession-level quantity of seeds to put into storage to minimize seed (gene)bank regeneration or re-collection Open
Seed (gene)banking is an effective way to conserve cultivated and wild plant diversity. However, long-term funding is not always consistently sufficient, and there is a need to both strengthen the effectiveness of genebank operations and m…

Digital image analysis for automated seed germination assessment in genebank viability testing Open
Genebanks play a vital role in conserving the world’s plant genetic resources. However, the capacity of seeds to germinate declines over time and culminates in the loss of viability even under the best long-term storage conditions. Geneban…

Evaluating seed longevity: use of RNA integrity to characterize variation within species of legume grains Open
Seed genebanks must maintain collections of healthy seeds and regenerate accessions before seed viability declines. Seed shelf life is often characterized at the species level; however, large, unexplained variation among genetic lines with…

Estimation of seed viability constants (<i>K</i><sub>E</sub>,<i>C</i><sub>W</sub>) for lentil (<i>Lens culinaris</i>) Open
Orthodox seed longevity systematically increases with reduction in temperature and moisture content, as described by the Ellis and Roberts viability equations. These equations have species-specific parameters which quantify the inherent lo…

CGIAR genebank viability data reveal inconsistencies in seed collection management Open
Genebanks underpin global food security, conserving and distributing agrobiodiversity for use in research and breeding. The CGIAR collections include >700,000 seed accessions, held in trust as global public goods. However, the role of gene…

Why Seed Physiology Is Important for Genebanking Open
Genebank management is a field in its own right; it is multifaceted, requiring a diverse set of skills and knowledge. Seed physiology is one area that is critical to the successful operation of seed genebanks, requiring understanding of se…

Further Evidence That the Genebank Standards for Drying Orthodox Seeds May Not Be Optimal for Subsequent Seed Longevity Open
Maximizing seed longevity is important for genebanks to efficiently manage their accessions, reducing the frequency of costly regeneration cycles and the loss of genetic integrity. Research on rice seeds has shown that subsequent longevity…

High-temperature stress during drying improves subsequent rice (<i>Oryza sativa</i> L.) seed longevity Open
Post-harvest drying prolongs seed survival in air-dry storage; previous research has shown a benefit of drying moist rice seeds at temperatures greater than recommended for genebanks (5–20°C). The aim of this study was to determine whether…

Rethinking the approach to viability monitoring in seed genebanks Open
Seed viability monitoring, usually through a germination test, is a key aspect of genebank management; a low viability result triggers the regeneration of an accession in order to ensure that the genetic diversity of the accession is conse…

Seed drying regime and subsequent longevity in rice (Oryza sativa L.) genebank accessions Open
Maximising potential seed longevity during harvesting and drying will minimise later testing and regeneration, accumulation of genetic damage, and depletion of seed accessions in genebanks. Experiments with freshly-harvested seeds at the I…

Increases in the longevity of desiccation-phase developing rice seeds: response to high-temperature drying depends on harvest moisture content Open
Seeds harvested at a moisture content where, according to the moisture desorption isotherm, they could still be metabolically active (>16·2 %) may be in the first stage of the post-mass maturity, desiccation phase of seed development and t…
