Methods of evaluation, effects of intermating and results of one cycle of S₁ family recurrent selection in barley

Creator:: Mareck, James
Abstract:: The focus of this study was to determine if S₁ family recurrent selection might be successfully used for barley improvement. Objectives were: 1) to identify suitable methods of evaluating grain yield in small plots, 2) to study the effects of intermating on mean values and variances of selected agronomic characters,...

Gluten protein polymeric composition and allelic variation as related to bread-making quality in durum wheat (Triticum turgidum L. var. durum)

Creator:: Ammar, Karim
Abstract:: Attempts to develop dual-purpose durum wheat cultivars for both pasta and bread-making have been unsuccessful. To better understand this limitation, thirty durum genotypes, selected based on their diverse geographical origin, and five bread wheat cultivars were compared as to their flour mixing properties, dough physical characteristics and baking performance. The...

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...

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...

Genetic variability for kernel hardness in two soft winter wheat (Triticum aestivum L.) cultivators

Creator:: Albahouh, Muhammed S.
Abstract:: To remain competitive in the international marketplace, soft white wheat cultivars grown in the Pacific Northwest must have consistent and predictable flour properties including kernel texture. As a consequence, there is a need to develop wheat cultivars for specific end uses. Wheat cultivars with very soft kernels are used largely...

A study of methods of parental evaluation using testers to predict subsequent progeny performance in winter wheat (Triticum aestivum L.)

Creator:: Alexander, William Larry
Abstract:: The major objective of this study was to determine why certain winter wheat cultivars, when hybridized, will produce a greater proportion of desirable plants in subsequent, segregating generations. Three winter wheat parents were chosen as the experimental material, based on their known performance as parents. Yamhill and Pullman Selection 101...

Agronomic performance of six winter wheat dwarfing sources when crossed to isogenic lines for Norin 10 Rht loci

Creator:: Pedretti, Ricardo
Abstract:: Six genetically diverse dwarfing sources of winter wheat were compared to four isogenic lines for the height reducing genes Rht₁ and Rht₂. Parents and generations through the F₃ including backcrosses to the respective parents were analyzed. Seedling response to gibberellic acid and tests for allelism for plant height were employed...

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;...

Genotype-environment interaction in winter wheat F₁ progeny

Creator:: Peterson, C. J.
Abstract:: Seven winter wheats were evaluated for plant height, the components of yield and yield in a diallel cross at Pendleton, Oregon and Lind, Washington. An additional parent was added to the diallel cross at Pullman, Washington. Two levels of nitrogen and five replications were utilized at each of the locations....
