Research Project: Advanced Testing of Hop Germplasm

Location: Forage Seed and Cereal Research Unit

Project Number: 2072-21000-051-016-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Aug 1, 2020
End Date: Oct 31, 2023

Develop new hop germplasm with resistance to powdery and downy mildew.

Experimental germplasm will be provided for distribution to commercial hop growers. The lines will be planted in large scale blocks and managed under commercial conditions. Lines will be evaluated for: yield/vigor; susceptibility to powdery mildew, aphids and spider mites when they occur; bittering acid composition; storage-ability; and essential oil composition. Experimental lines will be harvested and used for pilot brewing. Germplasm will be provided for greenhouse pre-screening and a “pot-in-pot” low trellis field for sex, powdery and downy mildew resistance/tolerance and vigor. Data will be used for selection of clones for advancement into field experiments.
