Influence of phosphorous and lime application on root growth and grain yield of two winter wheat cultivars (Triticum Aestivum, L em thell)

Creator:: Boulger, Mary Caroline
Abstract:: Differential grain yield response of two winter wheat cultivars ('Yamhill' and'McDermid) when grown on acid soils prompted this investigation. Root samples were taken at two soil depths at late tillering and anthesis from plots established on an acid nonpareil soil in Douglas County, Oregon. The soil pH was 5.2-5.3 and...

Possible associations between three procedures to measure noodle starch quality in winter wheat (Triticum aestivum L.)

Creator:: Weight, Chris (Christopher Thompson)
Abstract:: Until recently, the viscoamylograph had been the primary method for measuring starch as it relates to noodle quality in wheat. This method requires a large sample of flour and is time consuming. With the introduction of the rapid visco-analyser (RVA) in 1986 and the more recent flour swelling volume procedure,...

Performance of five winter wheat cultivars when grown in composite and pure stand populations under different environmental stresses

Creator:: Indelen, Erdogan
Abstract:: Five genetically and morphologically different winter wheat cultivars, Hyslop (H), Yamhill (Y), Paha (P), Luke (L), and Sprague (5) were blended in all possible combinations. These composites plus the five pure stands were planted in the fall of 1973 at three environmentally diverse locations in Oregon: Hyslop Agronomy Farm, Corvallis;...

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...

A comparison of three systems of phenotypic selection for grain yield in three spring barley populations

Creator:: Hayes, Patrick M.
Abstract:: Concerns regarding the most effective means of evaluating segregating generations of spring barley prompted this investigation. Three methods of selection were considered: bulk, pedigree, and single seed descent. F₆ lines derived by each method were grown in a replicated yield trial. The effectiveness of each method was measured in terms...

Potential reciprocal differences for selected traits in six different F₁ wheat populations

Creator:: Stein, Ira Steven
Abstract:: Concerns about the possible reciprocal differences resulting from systematic crossings of winter and spring wheat gene pools prompted this investigation. If traits can be improved by simply reversing the direction of a cross, then identification of the best female parent in a cross would be helpful for breeding programs. Two...

Possible associations of soluble carbohydrates with chemical desiccation and drought resistance in winter wheat

Creator:: Cerono, Julio Cesar
Abstract:: Drought is a major limiting abiotic stress influencing wheat production in many parts of the world. The erratic nature of water deficits makes breeding and selection for drought resistance deficient. In environments with late season drought stress, yield losses are usually associated with kernel abortion or reduction in kernel growth....

Duration and rate of the grain filling period and subsequent grain yield in crosses between facultative and winter wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Mou, Beiquan
Abstract:: Concerns about the genetic control and environmental influence of various stages of development including the grain filling period, and the relationship between early maturity and grain yield prompted this study. The experimental material consisted of two facultative and two winter wheat cultivars. A dial!el cross, excluding reciprocals, was also developed...

Inheritance of Septoria leaf blotch resistance and the possible influence of heading date and plant height on the disease expression in a winter wheat cross

Creator:: Camacho Casas, Miguel Alfonso
Abstract:: Parental lines, Fi's and segregating populations (F₂, F₃ and BC's) including reciprocals were evaluated under field conditions to determine if genetic resistance per se exists for Septoria Leaf Blotch in a selected winter wheat cross. The experiment was conducted over a three year period with both natural infection and artificial...

Compensating effects and gene action estimates for the components of grain yield in winter wheat (Triticum aestivum, L. em Thell)

Creator:: Abi-Antoun, Michel
Abstract:: Five winter wheat cultivars and their diallel crosses were evaluated for plant height, harvest index, deading-maturity duration, the components of yield, (spikes per plant, spikelets per spike, kernel weight and kernels per spikelet)and total plant yield. Two diverse locations, Moro, a dryland site (250 mm annually) located in central Oregon...
