Interpretive Summary: As future advances in transformation technology allow insertion of useful genes into a broader array of target genotypes, the choice of targets will become more important. Targets should be genotypes that will pass to their progeny other useful characteristics, such as sensory quality characteristics, while improving agronomic performance or pest resistance. We have found that the use of certain lines as parents in peanut breeding resulted in decreased flavor quality and have identified specific lines which when used as parents will result in improved rather than decreased flavor quality. This information is particularly important if flavor quality is to be maintained or improved as the transgene is moved into breeding populations via sexual transfer.

Technical Abstract: As future advances in transformation technology allow insertion of useful genes into a broader array of target genotypes, the choice of targets will become more important. Targets should be genotypes that will pass to their progeny other useful characteristics, such as sensory quality characteristics, while improving agronomic performance or pest resistance. This is particularly important if flavor quality is to be maintained or improved as the transgene is moved into breeding populations via sexual transfer. Selection of genotypes with superior breeding values through the use of Best Linear Unbiased Prediction procedures (BLUPs) is discussed. Using a database of sensory attributes on 250 peanut cultivars and breeding lines, the application of BLUP procedures to the selection of parents for improvement of roasted peanut and sweet attributes in breeding of peanut cultivars is illustrated.
