Research Project: ENHANCEMENT OF SMALL FRUIT GERMPLASM THROUGH GENOMIC CHARACTERIZATION AND GENETIC IMPROVEMENT WITH EMPHASIS ON DISEASE RESISTANCE

Location: Genetic Improvement of Fruits and Vegetables

Project Number: 1245-21220-189-00
Project Type: Appropriated

Start Date: Mar 20, 2008
End Date: Mar 19, 2013

Objective:
Develop improved cultivars and enhanced germplasm of strawberry, blueberry, and black raspberry that possess desirable horticultural traits, including broad environmental adaptation, disease resistance, longer fruiting season, high yield, and excellent fruit and plant quality characteristics. Develop methodologies to more effectively and precisely identify and select disease-resistant small-fruit genotypes.

Approach:
Small fruit germplasm from established cultivar materials to wild types will be evaluated using both classical and molecular techniques. Scientists will develop improved disease screening methods, identify and evaluate disease resistant germplasm, and develop improved methods of incorporating the resistance into superior germplasm. Genetic aspects of both pathogen and host variation will be studied. Concurrent with selection for disease resistance, breeding will emphasize selection for other factors necessary to the development of successful cultivars, with particular emphasis on fruit quality and phytonutrients, environmental adaptation, and adaptation to mechanization. Vaccinium (blueberry and cranberry) breeding and disease work will be carried out at Chatsworth, New Jersey, and Fragaria (strawberry) and Rubus (blackberry and raspberry equals brambles) work will be carried out at Beltsville, Maryland.
