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....

Yield loss assessment in nonprotected winter wheat varieties (Triticum aestivum, L. em Thell)

Creator:: Camacho Casas, Miguel Alfonso
Abstract:: The effects of some soil- and foliar-borne biotic factors on grain yield and the components of yield were evaluated using five winter wheat varieties sown at two dates. Within each planting date, varieties were grown under four different combinations of two soil treatments (fumigation and nonfumigation) and two foliar treatments...

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...

Combining ability and associations of agronomic traits involving three sources of dwarfism in wheat (Triticum aestivum, L. em Thell)

Creator:: Maya de Leon, Jose Luis
Abstract:: Three genetically different dwarf cultivars of spring wheat were evaluated as potential sources of short stature to use in a wheat improvement program. The study involved a five parent diallel cross which included a semidwarf, a standard height and three dwarf cultivars. The genetic sources of dwarfism included a Norma...

Assessment of resistance and inheritance to Barley Yellow Dwarf Virus disease (BYDV) in five wheat cultivars (Triticum aestivum L.)

Creator:: Tola, Jaime
Abstract:: Barley Yellow Dwarf Virus (BYDV) is a major disease of wheat. Unfortunately, unlike barley where the Yd2 gene provides adequate levels of resistance, the situation in wheat is more complex. This study was designed to provide information regarding: 1) evaluation of methods of measuring resistance among selected cultivars; 2) identification...

Inheritance and association of earliness and grain yield in four winter x spring wheat crosses (Triticum aestivum L. em Thell.)

Creator:: Firat, Ahmet Ertug
Abstract:: Parental and segregating populations derived from four winter x spring wheat crosses were investigated to obtain information concerning the inheritance and association of earliness, grain yield and yieldrelated traits. Feasibility of selecting in early generations for these characteristics was also evaluated. Four winter wheat cultivars (Hyslop, Yamhill, Bezostaia 1, and...

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...

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...
