Narrative
The Agricultural Research Service (ARS) announces the release of `USDA 21267M', a new high alpha content male hop (Humulus lupulus L.) germplasm. The defining characteristics of USDA 21267M are its high alpha acid levels observed in lupulin glands as well as good breeding value for yield, alpha and beta acid levels and high xanthohumol levels. It is expected that hop breeders will utilize this germplasm as a parent for high-yielding, high-alpha hop breeding material. USDA 21267M originated as a cross performed by USDA at Corvallis, OR in 1973 between `Comet? x USDA 21110M. The pedigree for this cross is: Comet/3/Bullion//Halletauer/OP. Thus, the genetic composition of USDA 21267M is 1/2 Comet, 1/4th Bullion, 1/8th Halletauer, and 1/8th unknown. This germplasm produces abundant pollen, is vigorous, and matures early in comparison to other male germplasm. Heritability studies performed in 1999-2000 under replicated field studies identified this accession as having the highest breeding value for yield, alpha acid levels, beta acid levels and xanthohumol levels when compared to 5 other important USDA male hop germplasm lines. Chemical analyses of USDA 21267M lupulin glands indicate its primary use as a breeding parent for aroma-type hop varieties where higher levels of beta acids in offspring are desired. Phenotypic measurements of 21267M showed alpha acids averaged 53.2% (v/v) in while beta acids averaged 18.1% (v/v) with alpha acids comprising 74% of the total bittering acids (v/v). This germplasm also exhibited low cohumulone levels of 28% and has good storage capabilities with a hop storage index of 0.259. No controlled experiments have been done on USDA 21267M for resistance to powdery mildew infection [caused by Pseudoperonospora humuli (Miyabe. and Takah.) G.W. Wilson] or downy mildew infection [caused by Pseudoperonospora humuli (Miyabe. and Takah.) G.W. Wilson] found in the Pacific Northwest. Field-based observations practicing normal fungicidal applications indicated no serious infections of either disease. Under normal growing conditions, early downy mildew infections are easily controlled with fungicides registered for use on hop. No cases of Verticillium wilt (caused by Verticillium albo-atrum) were observed in nursery plots. Growers are cautioned against growing USDA 21267M in known verticillium-infested fields due to the potential susceptibility of this variety based upon its parentage. No information is available on USDA 21267M 's susceptibility to hop aphids (Phorodon humuli Schank) and spider mites (Tetranychus urticae Koch) although infestations of these pests have not caused losses in test plots. The release of USDA 21267M provides a new hop germplasm exhibiting good breeding value, resistance to powdery mildew and intermediate resistance to downy mildew and potential for excellent storagabilty in offspring. Genetic material of this release has been deposited in the National Germplasm System at the USDA-Pacific Northwest Clonal Repository near Corvallis, OR. This material will be available for research purposes including the development and commercialization of new cultivars. It is requested that appropriate recognition be given if this germplasm contributes to the development of a new breeding line or cultivar.
