Narrative

Genotypic variance is necessary for trait improvement as limited diversity can reduce genetic gain in crop improvement. To maintain genetic diversity, a wealth of germplasm exists in the USDA-ARS sorghum [Sorghum bicolor (L.) Moench] collection, but most of the accessions are not adapted to temperate climates. To address this issue, the Reinstated Sorghum Conversion program (RSC, circa 2009-2014) converted 155 tropical accessions to combine height, early maturing F3 and BC1 F3 families. Herein the identification of 11 germplasm lines (Reg. No. GS-###, Tx3429 to Reg. No. GS-###, Tx3439) released by Texas A&M Agrilife Research in 2019 and derived from the RSC program are described. This germplasm was derived from F3, BC1 F3, and BC1 F4 RSC families that was selected based on testcross hybrid performance for either grain or silage production. Seven lines (Tx3429-Tx3435) are grain sorghum pollinators, one line is a seed parent, and four lines (Tx3436-Tx3439) are silage pollinators. These lines combined agronomic productivity with greater genetic diversity as confirmed via genotyping-by-sequencing. These eleven parental germplasms are being released to provide new genetic diversity for forage and grain hybrid improvement programs.
