Nature of the inheritance of gluten strength and carotenoid pigment content in winter by spring and durum wheat crosses (Triticum turgidum L. Var. durum)

Creator:: Ammar, Karim
Abstract:: Durum wheat cultivars for North-Eastern Oregon have to be competitive in terms of their yield potential with soft white winter wheat cultivars and meet strict quality requirements of the milling industry. Combining the high yield potential of fall planted durum wheat cultivars which have an acceptable level of winter hardiness...

Estimates of genetic variability resulting from single, top, and double cross populations in durum wheat (Triticum turgidum L. var. durum)

Creator:: Abdennadher, Mourad
Abstract:: The success of a plant breeding program depends upon the availability of useable genetic diversity. Such diversity may be enhanced depending on the type of hybridization strategy employed. Segregating progenies resulting from F2 populations, a double cross, and a top cross were compared for the amount of useable genetic diversity...

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...

Heritability estimates and associations for protein content and grain yield involving four winter wheat crosses (Triticum aestivum Vill., Host)

Creator:: Solen, Polat
Abstract:: Four agronomically and genetically diverse winter wheat parents were utilized as the experimental organisms. Atlas 66 and NB 68513 were selected as cultivars with a high and stable protein content when grown under different environmental condidtions. They are intermediate for grain yield when grown in the Pacific Northwest. Yamhill and...

Identification and inheritance of factors influencing the rate and duration of grain fill in selected wheat populations, (Triticum aestivum L. em Thell)

Creator:: Chuhe, Chen
Abstract:: To study the grain filling traits in wheat, two winter cultivars and four spring cultivars were selected. The resulting Fl, F2, F3 and backcrosses were tested. The following measurements were made: a) Visual traits for physiological maturity (PM), b) Grain dry weight accumulation, c) Regression models for grain filling period,...

Genetic and environmental factors influencing the effectiveness of early generation selection in a diallel cross involving four winter wheat cultivars (Triticum aestivum Vill., host)

Creator:: Daaloul, Abderrazak
Resource Type:: Dissertation

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...

Assessment of genetic resistance to strawbreaker foot-rot (Pseudocercosporella Herpotrichoides) in selected winter wheat (Triticum aestivum L.) cultivars

Creator:: Encinas-Mungarro, Andres
Abstract:: Strawbreaker foot-rot is a major limiting factor to cost efficient winter wheat production in the Pacific Northwest. Development of resistant cultivars has been hindered by the lack of adequate levels of genetic resistance and screening techniques which can consistently detect desired genotypes. Studies were conducted to determine if the reported...

Duration and rate of grain filling and subsequent grain protein content in selected winter wheat populations

Creator:: Mou, Beiquan
Abstract:: The lack of information regarding the inheritance of the duration and rate of grain filling, and the possible relationship between grain fill and grain protein content in wheat prompted this study. Early maturing Chinese cultivars, 'AI Feng 2' and 'CB 83-52', and late maturing cultivars adapted to Oregon, 'Stephens' and...
