Project Number: 5302-21220-004-09
Project Type: Specific C/A

Start Date: Sep 27, 2002
End Date: Jul 31, 2004

Objective:
1) Determine if molecular markers for Pierce's disease (PD) and Xylella Fastidiosa (Xf) resistance in family 9621 are linked to PD and Xf resistance in families 0023 and 501; 2) Develop additional markers for flower and fruit traits; 3) Introgress PD and Xf resistance into table and raisin grape quality.

Approach:
1) Resistant and susceptible individuals from families 0023 and 501 = [V. vinifera x (V. rupestris x M. rotundifolia)] will be tested with markers developed for Pd and Xf resistance in family 9621 = (V. rupestris x M. rotundifolia); 2) Fruit and flower characteristics will be scored and linkages with molecular markers determined; 3) Resistant individuals from families 0023 and 501 will be backcrossed to advanced breeding selections with the best table and raisin grape quality to develop table and raisin grape germplasm with PD and Xf resistance.
