Narrative
The sorghum germplasm lines R.LBK1 and R.LBK2 were developed and released by the United States Department of Agriculture in Lubbock, TX, in 2017 because of their high degree of resistance to the sugarcane aphid (SCA) [Melanaphis Sachari (Zehntner) (Hemiptera: Aphidae)]. Both lines were developed using the pedigree method of plant breeding and are confirmed to be restorer lines. Evaluation for SCA resistance was conducted in two field locations in Texas in 2016, as well as a greenhouse experiment at the USDA-ARS lab in Lubbock TX. Both lines express strong resistance to SCA pressures at both seedling and mature plant stages. Preliminary hybrids using highly susceptible seed parents (A-lines) have also shown strong resistance to the SCA, indicating that the resistance is dominantly expressed in F1 hybrids using these two lines. R.LBK1 and R.LBK2 are not completely immune to the SCA, but damage is greatly reduced and resistance is drastically apparent when compared to other susceptible sorghum lines and hybrids.
