Estimates of genetic variance and heterosis in F₁ winter x spring barley crosses (Hordeum vulgare, L.)

Creator:: Harrabi, Moncef Mohamed
Abstract:: Four winter and four spring barley cultivars along with their F₁ hybrids were grown on the Hyslop Agronomy Farm near Corvallis, Oregon, a high rainfall site (over 1000 mm annually) located in the Willamette Valley. The experiment consisted of four replications. Ten seeds of each F₁ and parents were seeded...

Association of selected traits with visual selection for yield in wheat (Triticum aestivum, L. em Thell.)

Creator:: Marciniak, Michael E.
Abstract:: Visual selection for grain yield may be a limiting factor in identifying superior yielding genotypes in a breeding program. This investigation was conducted (1) to compare the effectiveness of visual selection for grain yield by three selector groups representing different levels of plant breeding experience, and (2) to examine the...

Habitat Selection by Greater Sage-Grouse During Winter in Southeastern Oregon

Creator:: Hagen, Christian A., Willis, Mitchell J., Glenn, Elizabeth M., and Anthony, Robert G.
Abstract:: The distribution and geographic range of Greater Sage-Grouse (Centrocercus urophasianus) have been reduced by 56% since European settlement. Although loss and fragmentation of sagebrush (Artemisia spp.) habitats have been cited as the primary causes for the decline of the species, degradation of existing habitat also has been considered an important...

Effects of three herbicides on yields of five cultivars of winter wheat (Triticum aestivum L. em Thell)

Creator:: Yahyaoui, Amor
Abstract:: With the development of new selective herbicides and the frequent change in commercial wheat cultivars, information is needed as to the possible interaction between cultivars and herbicides. The responses of five genotypically diverse wheat cultivars (Bezostaya, Daws, Maris Hobbit, Stephens and Yamhill) to diuron [3-(3,4-dichloropheny1)-1,1- dimethylurea], diclofop methyl 2-[4-(2,4-dichlorophenoxy)phenoxy] propanoate...

Effect of late foliar applications of urea on protein, hardness, and yield of winter wheat cultivars (Triticum aestivum L.)

Creator:: Altman, David W.
Abstract:: The response of cultivars of winter wheat to foliar applications of urea was examined for grain protein content, yield, and kernel hardness. The objectives of this study were to measure the effect of urea on these three traits in diverse environments and to explain how potential responses could occur by...

Response of winter wheat (Triticum aestivum L. Em. Thell) to nitrogen and chloride fertilization in the presence of take-all root rot (Gaeumannomyces graminis var. tritici Walker)

Creator:: Maatougui, Mohamed El Hadi
Abstract:: Response from nitrogen and chloride fertilization was measured in field experiments on winter wheat (Triticum aestivum L. Em. Thell. var. 'Stephens' and 'Yamhill') grown in western Oregon in an environment with a range of susceptibility to take-all root rot (Gaumannomyces graminis var. tritici Walker). Cropping sequences and expected disease severity...

The effect of dimethyl sulfoxide (DMSO) on the radiosensitivity of the rough-skinned newt (Taricha granulosa)

Creator:: Lappenbusch, William L.
Abstract:: More than 2,000 male newts were collected during the summer and maintained unfed at 10°C both pre- and post-irradiation. Exposures ranging up to 30 kR were given with 300 kVp X-rays and ⁶⁰Co gamma rays. Half of the newts were injected (I. P.) with 15 g DMSO/kg (the maximum sublethal...

Radiotechnetium as an environmental contaminant : its metabolism by two freshwater species, the pearl mussel (Margaritifera margaritifera) and the rough-skinned newt (Taricha granulosa)

Creator:: Hevland, Mark
Abstract:: There is an increasing world inventory of radiotechnetium (mainly ⁹⁹Tc) and it is inevitable that some of this will be released to the environment. However, little is known about the environmental behavior of this element. This work examined technetium's behavior in two representative freshwater species, the pearl mussel (Margaritifera margaritifera)...
