Pear Genomics Project: Marker-Based Breeding Technologies for Pear Improvement

Traditional pear breeding, like most woody perennial crops, takes a long time due to the breeding cycle time and time to trait evaluation and can be quite expensive due to large land and labor requirements. Marker-based breeding technologies, as are routinely used in nearly all agricultural systems now, can potentially increase pear breeding efficiency. This funding request proposes to obtain a genome-wide genetic variation data from the entire Pyrus germplasm collection maintained by the ARS in Corvallis, OR. The primary goal and deliverable is to develop a database of the genetic variation in the Pyrus collection. In the jargon, this is called a “resequencing project”. In a subsequent funding cycle, these data will be used in combination with phenotypic trait variation toward development of marker-based breeding approaches in pear. Such a community-based project builds on the ongoing efforts to bringing together all US pear genetics researchers, and even foreign researchers, working toward a common goal and resource.
