Abstract

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 genebanks in contributing to global food security can only be realized if collections are effectively managed. Examination of the historical viability monitoring data from seven CGIAR genebanks confirmed that high seed viability was maintained for many decades for the various crops and forage species. However, departures from optimum management procedures were revealed, and there were insufficient data gathered to derive reliable estimates of longevity needed to better forecast regeneration requirements, estimate the size of seed lots that should be stored, and optimize accession monitoring intervals.

CGIAR基因库活力数据揭示了种子收集管理中的不一致性

基因库支撑着全球粮食安全，保护和分配农业生物多样性，以供研究和育种使用。国际农业研究磋商小组的藏品包括70万份种子，作为全球公共产品委托保管。然而，只有在有效管理基因库的情况下，才能实现基因库在促进全球粮食安全方面的作用。对来自7个CGIAR基因库的历史活力监测数据的检查证实，各种作物和饲料物种的种子活力保持了几十年。然而，与最佳管理程序的偏离被揭示出来，并且收集的数据不足，无法获得可靠的寿命估计，从而更好地预测更新需求，估计应该储存的种子批次的大小，并优化加入监测间隔。

期刊介绍： Global Food Security plays a vital role in addressing food security challenges from local to global levels. To secure food systems, it emphasizes multifaceted actions considering technological, biophysical, institutional, economic, social, and political factors. The goal is to foster food systems that meet nutritional needs, preserve the environment, support livelihoods, tackle climate change, and diminish inequalities. This journal serves as a platform for researchers, policymakers, and practitioners to access and engage with recent, diverse research and perspectives on achieving sustainable food security globally. It aspires to be an internationally recognized resource presenting cutting-edge insights in an accessible manner to a broad audience.
