Some genetic and environmental factors affecting performance and carcass measurements in swine

Creator:: Spurr, David Tupper, 1938-
Abstract:: Data from 592 litters of pigs farrowed and raised at the Oregon Agricultural Experiment Station at Corvallis from the spring of 1961 through the spring of 1968 were analyzed for effects of year and season of birth, breed, sex, inbreeding and age of dam on measures of fecundity, growth rate...

Exogenous and endogenous factors related to seed germination and vigor in certain varieties of sugarbeet Beta vulgaris L.

Creator:: Kim, Syng Chul
Abstract:: Studies were conducted on the causes of low germination of monogerm sugarbeet seed grown in western Oregon. Emphasis was placed on the identification and measurement of endogenous inhibitors as related to the germination and vigor. Both qualitative and quantitative analytical methods were applied to examine the organic substances in the...

Seed development and germination of monogerm sugar beets (Beta vulgaris L.) as affected by maturity

Creator:: TeKrony, Dennis M.
Abstract:: Maturation rates of monogerm sugar beet seed grown in Western Oregon were measured quantitatively to determine attainment of maximum seed development and germination. Seed was collected at various intervals after anthesis from two hybrid varieties representing the extremes in resistance (hard bolting) and susceptibility (easy bolting) to seedstalk development. The...

Heritability estimates and associations for protein content and grain yield involving four winter wheat crosses (Triticum aestivum Vill., Host)

Creator:: Solen, Polat
Abstract:: Four agronomically and genetically diverse winter wheat parents were utilized as the experimental organisms. Atlas 66 and NB 68513 were selected as cultivars with a high and stable protein content when grown under different environmental condidtions. They are intermediate for grain yield when grown in the Pacific Northwest. Yamhill and...

Genetics of sheep transferrins as determined by disc electrophoresis

Creator:: Nix, Carroll Eugene
Abstract:: A total of 902 plasma samples from the Rambouillet, Targhee, Columbia, Lincoln, and Suffolk breeds of sheep were analyzed for transferrin type by disc electrophoresis. Six transferrin types, Tf[superscript A], Tf[superscript B], Tf[superscript C], Tf[superscript p], Tf[superscript E], and Tf[superscript P], were found in the Rambouillet, Targhee, and Columbia breeds...

Chemical and genetic evaluation of high lysine and protein in selected barley crosses

Creator:: Helm, James Henry, 1944-
Abstract:: Four agronomically and genetically diverse spring barleys were used in a crossing program to study the inheritance of lysine in barley and to determine its possible association with certain agronomic and morphological characters. The cultivar Hiproly was used as the source of high protein and lysine. Characters measured included plant...

Influence of post-harvest management practices on plant growth and seed yield of cool season grasses

Creator:: Stanwood, Phillip Charles
Abstract:: Field and controlled environment chamber studies were carried out to evaluate modes of action of post-harvest treatments on the development and seed yield of cool season grasses. Red fescue (Festuca rubra L.) was used as the primary test species. There was no difference in total biomass production of red fescue...
Resource Type:: Masters Thesis

Influence of post-harvest burning, thinning, shading and residue management on the subsequent growth and seed yield of Festuca rubra L.

Creator:: Kim, Syng Chul
Abstract:: The effects of post-harvest burning of red fescue on production of shoots, roots and inflorescences as well as seed yield were determined at the clonal and community level by comparing fescue plants in a burned area with those in unburned plots within the same field. Studies were also conducted to...
Resource Type:: Dissertation

Nitrate reductase activity and inheritance of grain protein in six barley cultivars (Hordeum vulgare L. and Hordeum distichum)

Creator:: Samphantharak, Krisda
Resource Type:: Dissertation

Genetic variability and association between agronomic and quality characteristics in twenty-nine female genotypes of Humulus lupulus L.

Creator:: Roberts, Donald Day
Abstract:: The genetic variability in and association between 14 traits that affect maturity, yield, and chemical properties of its product. The plant characters measured were: vigor, flowering date, harvest date, yield, lateral length, nodes per lateral, cones per lateral, cones per vine, cone weight. Alpha-acid and beta-acid content of the cone,...
