Experimental studies on species relationships in T. turgidum ssp. carthlicum and T. aestivum ssp. carthlicoides

Creator:: Vieira, Luiz Gonzaga E.
Abstract:: A study of populations characteristics of T. turgidum ssp. carthlicum and T. aestivum ssp. carthlicoides was completed using numerical analysis. A sample of 74 accessions of ssp. carthlicum and 20 of ssp. carthlicoides were scored for 46 characters. It was established that three morphological distinguishable groups of ssp. carthlicum can...

Feasibility of developing bread wheat cultivars with acceptable protein content for non-traditional areas

Creator:: Lorenzo, Ariel
Abstract:: The objective of this investigation was to evaluate the possibility of developing high yielding wheat cultivars whose flour would result in acceptable loaf volumes for non-traditional bread wheat growing areas. Spring wheat germplasm employed included high protein hexaploid derivatives from Triticum dicoccoides, and selections from Argentina with good bread milling...

Yield loss assessment in nonprotected winter wheat varieties (Triticum aestivum, L. em Thell)

Creator:: Camacho Casas, Miguel Alfonso
Abstract:: The effects of some soil- and foliar-borne biotic factors on grain yield and the components of yield were evaluated using five winter wheat varieties sown at two dates. Within each planting date, varieties were grown under four different combinations of two soil treatments (fumigation and nonfumigation) and two foliar treatments...

Nitrogen management and variety selection for dryland production of hard red winter wheat in northeastern Oregon

Creator:: Jepsen, Daniel R.
Abstract:: Proper nitrogen (N) management and variety selection are important for profitable hard red winter (HRW) wheat production in the dryland growing regions of northeastern Oregon. In these dryland systems, N management for grain yield and grain protein concentration (GPC) is challenging due to climatic and year-to-year variation in production environments....

From germplasm development to variety release : the Oregon State University food barley experience

Creator:: Meints, Brigid M. A.
Abstract:: Barley (Hordeum vulgare L.) is one of the oldest known domesticated crops. Originally cultivated for human consumption, other end-uses have gained importance over the millennia. Barley is the fourth most important cereal crop in the world (FAO-STAT, 2011), and today it is mainly used as animal feed or malted for...

Seedling recruitment of hairy nightshade and other summer annual weeds in irrigated row crops

Creator:: Peachey, Ronald Edward
Abstract:: This study evaluated the effects of tillage system, rotational tillage sequences, and winter seed burial depth on weed seedling recruitment in irrigated cropping systems. Notill (NT) planting of vegetable crops reduced emergence of hairy nightshade by 77 to 99% and Powell amaranth emergence from 50 to 87% compared to conventional...

Continued exploration of barley genotype contribution to beer flavor and the application of this knowledge to variety development and release

Creator:: Morrissy, Campbell P.
Abstract:: Investigation on barley genotype contribution to beer flavor is a relatively new area of research but has interest from members of the malting barley supply chain. This body of work builds upon previous studies by approaching it from new angles that further supports the malting and brewing industries’ interests around...

Annual Forages Differ in Response to Partial-Season Irrigation Deficit in Both Spring Seeded and Summer Seeded Cropping Systems

Creator:: Fan, Qianqian
Abstract:: Water scarcity during summer becomes a serious problem in the Pacific Northwest, threatening forage production provided to livestock. Annual forages show great potential in handling drought because of their flexibility in seeding date and short growing season, and can shift the production to periods of feed shortage and fill the...

Assessment of genetic resistance to strawbreaker foot-rot (Pseudocercosporella Herpotrichoides) in selected winter wheat (Triticum aestivum L.) cultivars

Creator:: Encinas-Mungarro, Andres
Abstract:: Strawbreaker foot-rot is a major limiting factor to cost efficient winter wheat production in the Pacific Northwest. Development of resistant cultivars has been hindered by the lack of adequate levels of genetic resistance and screening techniques which can consistently detect desired genotypes. Studies were conducted to determine if the reported...
