Based upon the approach outlined in Objective 2 of the CRIS project 5358-21000-046-00D, experimental germplasm will be provided to Washington State University after being pre-screened in a greenhouse and a “Pot-in-pot” low trellis field for sex, powdery and downy mildew resistance/tolerance and vigor. Washington State University will be responsible for screening selected subset of individuals from this experimental germplasm for the following traits: 1) Yield/vigor 2) Susceptibility to powdery mildew, aphids and spider mites 3) Bittering acid composition 4) Storage-ability 5) Essential oil composition Washington State University has the right to work with a grower or growers to produce USDA-ARS germplasm as long as an appropriate USDA-ARS Material Transfer Agreement (MTA) is in place with said grower(s). Advanced experimental lines identified by USDA-ARS, for additional observation under semi-commercial production, will be increased and grown out by Washington State University using grower(s) for commercial multi-hill plots where data for two years subsequent to the baby year (year of establishment) on the above traits will be collected and recorded. As is the case with experimental germplasm, all necessary USDA-ARS MTA’s must be in place prior to releasing advance germplasm to grower(s) for off-station Advance Germplasm observations. New advanced experimental lines developed by Washington State University that have been pre-screened in single hill plots for at least 3 years will be provided to the USDA-ARS for inclusion in multi-hill plots sponsored by Hop Research Council and the Oregon Hop Commission. It is expected that experimental lines will be delivered in replicates of 2 – 5 clones per genotype. These lines will be screened for the same traits listed above if determined appropriate for such tests by the USDA-ARS. Data on all experimental germplasm will be provided to USDA-ARS in a timely fashion but no later than December 1st of the fiscal year.
