NOTICE OF RELEASE OF HARD KERNEL PUROINDOLINE ALLELE NEAR-ISOGENIC LINE HEXAPLOID WHEAT GENETIC STOCKS. USDA, Agricultural Research Service, Cultivar Release.

Interpretive Summary: These genetic stocks were developed by Dr. Craig F. Morris at the USDA-ARS Western Wheat Quality Laboratory, Pullman, Washington. These genetic stocks were released by the USDA-ARS in 2006 and will have direct benefit to the development of hard spring wheat cultivars in the Pacific Northwest and elsewhere. 'Alpowa' germplasm was used in the crossings. Alpowa is a publically-available USDA germplasm collection. It was cooperatively developed by Dr. Calvin Konzak, then spring wheat breeder at WSU, the USDA ARS Western Wheat Quality Laboratory, and others; it was released in 1994. The germplasm are indistinguishable from Alpowa. Further, they are expected to carry the Yr39 gene for high temperature adult plant resistance to stripe (yellow) rust (Puccinia striiformis West. f. sp. tritici) from Alpowa. Genetic material of this release has been deposited in the USDA National Plant Germplasm System (http://www.ars grin.gov/npgs/) where it will be available for research purposes, including development and commercialization of new cultivars.

Technical Abstract: The Agricultural Research Service, U.S. Department of Agriculture announces the release of seven hard kernel puroindoline allele near-isogenic line (NIL) hexaploid wheat (Triticum aestivum L.) genetic stocks (PI xxxxxx – PI xxxxxx) developed by Dr. Craig F. Morris at the USDA-ARS Western Wheat Quality Laboratory, Pullman, Washington. These genetic stocks were released by the USDA-ARS in 2006 due to the utility of such NILs in researching the effects of these puroindoline alleles on kernel texture and wheat grain end-use quality. Further, these NILs, being developed in the ‘Alpowa’ soft white spring wheat cultivar background, will have direct benefit to the development of hard spring wheat cultivars in the Pacific Northwest and elsewhere. A homozygous hard plant was selected for backcrossing using Alpowa as the recurrent parent and the aforementioned process was repeated. In addition to hard kernel texture, at each cycle the progeny were selected for the morphological and developmental characteristics of Alpowa. In all, seven backcrosses were conducted such that the general pedigree of each NIL is: Alpowa/donor parent/7*Alpowa. All crossing and propagation through the BC7F2 plant stage was conducted under glasshouse environments in the Washington State University (WSU) Plant Growth Facilities. The contribution of Alpowa (PI 566596) is hereby gratefully acknowledged. Alpowa is publically-available from the USDA germ plasm collection with no PVP restrictions. It was cooperatively developed by Dr. Calvin Konzak, then spring wheat breeder at WSU, the USDA ARS Western Wheat Quality Laboratory, and others; it was released in 1994. Morphologically and developmentally, these NILs are indistinguishable from Alpowa. Further, they are expected to carry the Yr39 gene for high temperature adult plant resistance to stripe (yellow) rust (Puccinia striiformis West. f. sp. tritici) from Alpowa. Genetic material of this release has been deposited in the USDA National Plant Germplasm System (http://www.ars grin.gov/npgs/) where it will be available for research purposes, including development and commercialization of new cultivars. It is requested that appropriate recognition be made if these genetic stocks contribute to research or the development of a new breeding line or cultivar.
