Chemically induced male sterility and natural out-crossing in selected wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Ekse, Ali Osman
Abstract:: Three chemicals SD 55446, SD 55447 and WL 84245 were found to induce male sterility in cultivars of wheat or triticale. Both SD 55446 and SD 55447 when applied at a concentration of 0.896 kg/ha resulted in 90% male sterility. However, SD 55447 caused female sterility at the same concentration...

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...

Performance of cultivars, hybrids and composites of winter wheat (Triticum aestivum L. em Thell) grown at three locations

Creator:: Verges, Ruben P.
Abstract:: The objective of this study was to compare three genetically different groups of winter wheat for their grain yield. Experimental material consisted of parental lines grown in pure stands, hybrids, and 1:1 mixtures of the parental combinations. Three sites were employed to evaluate possible interactions between the different groups across...

EM-MAC : an energy-aware multi-channel medium access control protocol for multi-hop wireless networks

Creator:: Sivanantha, Akhil
Abstract:: The stupendous growth in wireless and mobile devices in the recent years has prompted researchers to look at innovative approaches that enable effective use of the available resources. In this thesis, we propose a medium access control (MAC) protocol, referred to as EM-MAC, that enables wireless devices with multi-channel access...

Hybrid conjugate gradient-Occam algorithms for inversion of multifrequency and multitransmitter EM data

Creator:: Egbert, Gary D.
Abstract:: We describe novel hybrid algorithms for inversion of electromagnetic geophysical data, combining the computational and storage efficiency of a conjugate gradient approach with an Occam scheme for regularization and step-length control. The basic algorithm is based on the observation that iterative solution of the symmetric (Gauss-Newton) normal equations with conjugate...

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...

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...

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...

Time and duration of growth stages and subsequent grain yield in selected wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Choi, Byung Han
Abstract:: The need to develop a shorter life cycle wheat cultivar which would be more adapted to multiple cropping systems prompted this study. Thus the following information was obtained. Greatest variations in developmental patterns were found in the stem elongation, booting, inflorescence emergence and anthesis for five winter and five spring...
