$138,424for <strong>2012</strong>-2014 for both raspberry and strawberry breeding<br />

Description: The program will develop new red raspberry cultivars for use by commercial growers<br />

in <strong>Washington</strong>. Using traditional breeding methods, the program will produce seedling populations,<br />

make selections from the populations and evaluate the selections. Selections will be evaluated for<br />

adaptation to machine harvestability by planting selections with cooperating growers. Promising<br />

selections will be propagated for grower trials and superior selections will be released as new<br />

cultivars. Specific traits to incorporate into new cultivars are high yield, machine harvestability,<br />

raspberry bushy dwarf virus (RBDV) resistance and root rot tolerance with superior processed fruit<br />

quality.<br />

Justification and Background: The Pacific Northwest (PNW) breeding programs have been<br />

important in developing cultivars that are the basis for the industry in the PNW. New cultivars are<br />

needed that are more productive, machine harvestable, RBDV resistant and tolerant to root rot while<br />

maintaining fruit quality. Replacement cultivars for 'Willamette' and 'Meeker' and new cultivars<br />

that extend the season are needed. With 99% of the <strong>Washington</strong> production used for processing,<br />

new cultivars need to be machine harvestable.<br />

There has been a history of cooperation between the breeding programs in Oregon, British<br />

Columbia, and <strong>Washington</strong> and material from other programs evaluated. This cooperation needs to<br />

continue as cultivars developed by these programs will be of value to the entire PNW raspberry<br />

industry.<br />

Relationship to WRRC Research Priorities: This project addresses a first-tier priority of the<br />

WRRC: Develop cultivars that are summer bearing, high yielding, winter hardy, machineharvestable,<br />

disease resistant, virus resistant and have superior processed fruit quality<br />

OBJECTIVE: Develop summer fruiting red raspberry cultivars with improved yields and fruit<br />

quality, and resistance to root rot and raspberry bushy dwarf virus. Selections adapted to machine<br />

harvesting or fresh marketing will be identified and tested further.<br />

Procedures: This is an ongoing project that depends on continuity of effort. New crosses will be<br />

made each year, new seedling plantings established, new selections made among previously<br />
