Registration of Tx3440 through Tx3482 sorghum germplasm

The sorghum [Sorghum bicolor (L.) Moench] germplasm lines Tx3440–Tx3482 (Reg. no. GP‐900–GP‐942, PI 695271–PI 695313) were developed and released by Texas A&M AgriLife Research, Lubbock, TX, in 2020. Breeding crosses from these lines were made in Lubbock, TX, with grow‐out and selection of subsequent generations completed in breeding nurseries throughout Texas over a period of years. Once selected, these lines were test for agronomic performance in replicated trials across multiple locations and years. Within the set, Tx3340–Tx3482 represent diverse pedigrees and an array of combinations of grain color, plant color, and other agronomic traits. The lines are individually resistant to selected abiotic (pre‐ and/or post‐flowering drought) stress and biotic stress (grain weathering caused by diverse genera that include Fusarium spp., Curvularia spp., and Alternaria spp.; and anthracnose caused by Colletotrichum sublineola). These lines provide the sorghum industry with sources of drought tolerance, grain weathering, and anthracnose resistance in a diverse array of elite genetic backgrounds for use as seed parent lines for hybrid production and for new line development.
