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...

Kernel hardness, protein, and viscosity as predictors of udon-noodle quality

Creator:: Ruddenklau, Helle G.
Abstract:: The Asian noodle market is responsible for the increased volume of wheat imported to that region in recent years. Soft white wheat produced in the Pacific Northwest is mainly used for baked products, whereas an Australian wheat, Australian Standard White, is preferred for noodles. To enter this market soft white-wheat...

Nature of inheritance, genotype-environment interaction and association of selected agronomic characters in crosses of winter X spring wheats (triticum aestivum L. em Thell)

Creator:: Brajcich, P.
Abstract:: This investigation was motivated by the apparent increase in genetic variability resulting from the systematic combining of gene pools represented by winter and spring types of wheats. It was the objective of this study to provide information regarding the nature of this genetic variability for nine agronomic characters in populations...

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....

The inheritance of stem rust (Puccinia graminis graminicola) resistance in perennial ryegrass (Lolium perenne)

Creator:: Rose, Crystal A.
Abstract:: Three stem rust Puccinia graminis graminicola, resistant sources of perennial ryegrass, Lolium perenne, 4A, 48A, and 77A, were crossed in a partial diallel design with one susceptible source, MP-2, resulting in six crosses excluding reciprocals. The F1's and cloned parental populations were inoculated in the field and rated on a...

Chemically induced pollen supression and subsequent natural outcrossing in selected wheat cultivars (Tritcum aestivum L. en Thell)

Creator:: Lewis, Hal A.
Abstract:: Effective chemical control of pollination would provide an alternative to the cytoplasmic male-sterile system in hybrid wheat (Triticum aestivum L.) production. The objective of this study was to determine concentration, formulation, growth stage of application and genotypic effects on levels of induced pollen suppression and subsequent natural out-crossing from foliar...

Genotype-environment interaction and phenotypic stability of selected winter wheats (Triticum aestivium L. em Thell)

Creator:: Larson, Mark J., 1962-
Abstract:: Extensive research has been devoted to evaluating potential genotype-environment interactions. However, plant breeders are still in need of a simple way to describe how genotypes respond to different locations and years. In an environmentally diverse state like Oregon, significant genotype-environment interactions do occur The resulting lack of association between actual...

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 expression of embryo maturation genes in wheat and the role of abscisic acid

Creator:: Berge-Chandler, Sonja Kay
Abstract:: A set of genes which show developmental and tissue specificity are expressed late in embryo maturation during grain formation in wheat (Triticum aestivum). Two members of this maturation gene set (MGS) are Em and triticin, a 7S globulin. Results presented here show that during embryogenesis, the expression of Em mRNA...
