Genetic stock collections have played an important role in shaping breeding strategies in many crops. With the advance in genomics, they are now essential tools for identifying genes underlying important agronomic traits. The objective of this work is to formally register and document the release of historical sorghum [ Sorghum bicolor (L.) Moench] genetic stocks originally collected and curated by the late USDA‐ARS sorghum geneticist Keith Schertz. The seeds from the original collection were revitalized at the USDA‐ARS Experiment Station at Lubbock, TX in 2004 and 2006, and evaluated for phenotypic variations in 2009. The collection consists of 507 lines and accessions (Reg. No. GS‐144, PI 663217 through Reg. No. GS‐650, PI 663723). This collection displays significant variation in growth, developmental, and agronomic traits, such as seedling vigor, leaf/vegetative organs, reproduction, maturity, height, and grain quality. Combined with advanced genomic tools, these genetic stocks are vital resources for elucidating the fundamental pathways that make sorghum and other related grasses unusually tolerant to drought and heat stress, have moderate to low requirements for fertilizer, and highly productive under diverse environmental conditions.
