Genetic engineering will be utilized to improve traits that have been either impossible or too time consuming to approach through traditional techniques. These traits include the development of dwarfing rootstocks for Pyrus (pear) and Prunus (stone fruits), the development of Plum pox virus resistant stone fruits, the improvement of fruit quality traits including the development of stoneless stone fruits, and the production of early flowering lines for speeding the fruit breeding process. We have developed a rapid high throughput transformation system in plum and a technology for early flowering and fruiting. We will use this system to rapidly test genes of interest. Those of interest will be applied for the improvement of stone fruits, particularly plum, and also pear. The genetically engineered plants developed at EPCOT will be further evaluated at Kearneysville in the greenhouse and field (with appropriate permits). The work at EPCOT is critical to us achieving our research project plan's milestones. The ARS staff at EPCOT is competent, motivated, and experienced. The facilities are good. We feel that achieving the objectives of the five-year-plan will provide not only good scientific information but also will lead us to the development of exciting new products for the pear and stone fruit industries.
