Evaluation of four quality factors in a selected winter x spring wheat cross (Triticum aestivum Vill., Host)

Creator:: Schumaker, Karen Sue
Abstract:: The nature of the genetic variation associated with a cross involving winter and spring wheat parents for four quality factors was evaluated. Yamhill, a soft white winter wheat, and Inia 66, a hard red spring wheat, were selected as parents for this study. They represented distinctly different phenotypes for the...

A comparison of two methods of divergent mass selection for heading date in two winter wheat (Triticum aestivum L. em Thell) crosses

Creator:: Frederickson, Leslie John
Abstract:: Responses to two cycles of mass selection for heading date, followed by selfing or intermating, were studied in two diverse winter wheat (Triticum aestivum L. em. Thell) crosses. Selection was bidirectional, resulting in early and late populations for each mating system, cycle, and cross. The influence of mass selection for...

Tissue culture and plant regeneration from immature embryo explants of twenty-two genotypes of barley, Hordeum vulgare L.

Creator:: Goldstein, Cindy S.
Abstract:: Immature embryo explants taken eight days after anthesis were used to establish callus cultures of spring barley. Two types of calli were observed. A soft watery callus which produced a limited number of shoots and a harder yellowish callus that gave rise to numerous green primordia and shoots. Gamborg's B5...

Association and inheritance of earliness and winterhardiness in four winter x spring wheat crosses (Triticum aestivum Vill., Host)

Creator:: Yakar, Kamil
Abstract:: The purpose of this study was to determine the nature and amountof genetic variation and possible associations between winterhardinessand earliness in winter x spring wheat crosses.Four winter wheat cultivars selected for differences in earlinessand winterhardiness were crossed with a nonhardy, day length insensitivespring wheat cultivar. The following year, experiments containing...

Prediction of kernel hardness and grain protein based on the performance of F₃ and F₄ populations derived from ten wheat crosses (Triticum aestivum L. em Thell)

Creator:: Hazar, Necati
Abstract:: Ten wheat crosses (four winter x spring and six winter x winter) involving F₃ and F₄ generations and their respective winter parents were used to determine whether the early generation selection would be effective for kernel hardness and grain protein content. In 1980, twenty individual F₂ plants were selected with...

Adaptability of winter wheat cultivars to dryland conditions and their response to water stress

Creator:: Keim, Don Lee
Abstract:: Winter wheat cultivars (Triticum aestivum) were evaluated for their response to water stress and adaptability to a wide range of moisture limited environments. Grain yield was analyzed for ten cultivars at six locations across four years. Regression of the cultivar mean on the year-location mean was used as a measure...

The influence of plant densities on gene action estimates and associations in seven winter wheat parents and their F₂ progeny

Creator:: Saini, Surinder Kumar
Abstract:: The F₂ progeny from a diallel cross involving seven winter wheat parents along with the parents were grown at the Hyslop Agronomy Farm near Corvallis, Oregon to determine the influence of three plant densities on gene action estimates for yield and its primary components. The plant densities were designed to...

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;...

Influence of different nitrogen and moisture levels on the expression of grain yield and protein content in selected wheat (Triticum aestivum, L. em Thell) and barley (Hordeum vulagre, L. em Lam.) cultivars

Creator:: Gomez-Pando, Luz
Abstract:: This investigation was conducted to provide information regarding 1) the relationship between the nitrogen percentage in the vegetative tissue of wheat and barley at various growth stages with grain protein and 2) to evaluate the possible association between grain yield and grain protein as influenced by different cultivars, nitrogen levels...
