Interpretive Summary:

Technical Abstract: Genebanks systematically house and safeguard world-wide crops and wild species genetic diversity. The accessions are maintained in ex situ and can be used to improve productivity, nutritional quality, disease resistance, value and sustainable agriculture by current and future plant breeders, and researchers. The USDA -ARS National Small Grains Collection (NSGC) and the Genetic Stocks Oryza (GSOR) collection maintain about 19,000 and 38,000 accessions, respectively. These accessions provide rice breeders and researchers with genetic diversity and require careful and timely rejuvenation and characterization to ensure that they continue to live on for future generations to combat the mounting global challenges associated with an ever-changing environment. To address some of the challenges faced by genebanks such as misidentification, seed mixtures, duplication, and lack of resources, a handbook of standard procedures and operations was developed. The handbook details the processes that occur when seeds are received from NSGC and GSOR to packing of seed after harvest. The handbook provides details on trait descriptors for which data is collected, information on diseases, plant growth stages to collect images and leaf sample collection for genotyping. This document ensures that the germplasm is effectively, consistently, and efficiently characterized from year to year. It will also provide rice breeders, researchers and educators with a template when evaluating their own research and seeking to submit rice varieties to the collection.
