The sorghum [Sorghum bicolor (L.) Moench] germplasm Tx3361 (Reg. No. GP-661, PI 659454) was developed and released by the Texas Agrilife Research sorghum breeding program in January 2010. This germplasm is unique because it lacks a key factor that represses alien-pollen growth on the stigma. The inability to repress alien pollen-tube growth increases the frequency of interspecific and intergeneric fertilization in sorghum. This increase is influenced by both the specific species and particular cultivars being tested. The line was developed using pedigree-breeding approaches in breeding nurseries in College Station and Weslaco, TX. Selection was based on agronomic adaptability and the presence of alien-pollen-tube growth (detected via fluorescence microscopy). This line provides sorghum improvement programs with a unique opportunity to create interspecific and intergeneric sorghum hybrids for use as introgression parents. © Crop Science Society of America.
