Mapping and introgression of disease resistance genes in barley (Hordeum vulgare L.)

Creator:: Toojinda, Theeryut
Abstract:: Molecular tools, coupled with unique germplasm stocks and rigorous phenotyping, are useful for developing a better understanding of qualitative and quantitative disease resistance genes in plants. The identification of molecular markers linked to all types of resistance genes provides opportunities for implementing a range of resistance breeding strategies, ranging from...

Cephalosporium stripe of wheat : seedling-based resistance screening and pathogenic variability

Creator:: Cowger, Christina
Abstract:: Cephalosporium stripe of wheat (Triticum aestivum), caused by the soilborne fungus Cephalosporium gramineum, results in significant yield reductions in dryland winter wheat crops of the U.S. Pacific Northwest. The development of resistant cultivars offers the best hope for disease control. Breeding for resistance is hampered by the long trial times...

Genetic resistance to eastern filbert blight

Creator:: Coyne, Clarice Jean
Abstract:: Eastern filbert blight, caused by Anisogramma anomala (Peck) E. Muller, is a serious threat to hazelnut (Corylus avellana L.) production. Resistant cultivars offer the best control. Screening systems were needed to reliably identify disease, particularly in immune progeny derived from 'Gasaway'. An indirect enzyme-linked immunosorbant assay (ELISA) was developed using...

Effects of sampling design, estimators, and variability on groundfish management in Oregon

Creator:: Crone, Paul R. Jr
Abstract:: Sampling error associated with estimates of species composition and age composition of commercial groundfish landings in Oregon from 1989 to 1991 is documented to evaluate the impact of variable landing data on fisheries management and monitoring programs. The statistical reliability and bias associated with two multistage sampling designs are investigated...

Effect of wheat cultivar mixtures on populations of Puccinia striiformis races

Creator:: DiLeone, Julie A.
Abstract:: This study quantified the frequency of simple versus complex races of Puccinia striiformis Westend. in mixtures of wheat cultivars possessing different race-specific resistance genes. A simple race of a pathogen can infect only one component, and a complex race of the pathogen can infect two or more components of an...

Evaluation of tree forage as a nontraditional feedstuff for small livestock

Creator:: Ayers, Anne Christine
Abstract:: Five experiments were conducted to evaluate tree forage as a feedstuff for small livestock, using the foliage of black locust (Robinia pseudoacacia) and hybrid poplar (Populus spp.). In the first trial, rabbits were fed diets containing 40% alfalfa (control), and 10%, 20% and 40% poplar leaves (PL) from untrimmed or...

Isozyme variation and inheritance in hazelnut

Creator:: Cheng, Suozhan
Abstract:: Inheritance of eight enzyme systems, alanine aminopeptidase (AAP), aspartate aminotransferase (AAT), aconitase (ACON), glucose phosphate isomerase (GPI), malate dehydrogenase (MDH), 6-phosphogluconate dehydrogenase (6-PGD), phosphoglucomutase (PGM), and shikimate dehydrogenase (SDH) was studied in hazelnut (Corylus avellana L.) by either polyacrylamide gel electrophoresis (PAGE) or starch gel electrophoresis. Three isozymes were detected...

Geographic variation in central Oregon ponderosa pine (Pinus ponderosa Laws.) : seed germination; seed, wing, and cone morphology; seed color

Creator:: Weber, John C., 1948-
Abstract:: Geographic variation was investigated among 225 locations from five geographically disjunct regions in central Oregon. Characters included: germination speed and uniformity in two test environments differing in stratification period and incubation temperature; weight, three dimensions and three 'angles' of seeds; weight and three dimensions of wings; cone length and scale...
