Genotype by Environment Interactions and Selection Responses of Two Maize Populations to Reciprocal Recurrent Selection in a High-Yield Environment (Corn)
A selection program using reciprocal recurrent selection procedures in maize (Zea mays L.) involving intra- and interpopulation selection were used for BS10 and RSSSC. Intrapopulation selection included phenotypic mass selection for multiple leaf and stalk-rot diseases resistance and S(,1) family …

ΕΛΕΓΧΟΜΕΝΗ ΜΑΖΙΚΗ ΚΥΨΕΛΩΤΗ ΕΠΙΛΟΓΗ ΓΙΑ ΑΠΟΔΟΣΗ ΣΤΙΣ ΔΙΑΣΠΩΜΕΝΕΣ ΓΕΝΕΕΣ ΕΝΟΣ ΑΠΛΟΥ ΥΒΡΙΔΙΟΥ ΚΑΛΑΜΠΟΚΙΟΥ (ZEA MAYS L.)
CONTROLLED MASS SELECTION WITHOUT COMPETITION (E.M.E.E.A.) AND UNDER COMPETITION (E.M.E.Y.A.) APPLIED, TOGETHER WITH UNCONTINUED PEDIGREE SELECTION (Γ.Ε.Ε.Α. AND Γ.Ε.Υ.Α.), ΙΝ ΤΗΕ F4, F5 AND F6 OF THE SINGLE MAIZE HYBRID Ι.Σ.027 (ZEA MAYS L.). ALL SELECTIONS WERE IN HONEYCOMB DESIGNS, WHERE THE …

Index, Individual Trait, and Tandem Selection to Improve a Maize Synthetic for Yield, Corn Borer, and Disease Traits
… between pairs of traits, to construct two selection indexes designed to improve the synthetic for yield and resistance to CB and common Illinois maize diseases simultaneously, to predict gain from selection, and to determine adequate numbers of replicates and plants per plot for half-sib …

Three studies in marker-assisted plant breeding
… to conduct reciprocal recurrent genomic selection for stress-tolerant hybrid rice. Third, we compare the effects of using overlapping and discrete selection generations in recurrent mass phenotypic, genomic, and genomic optimum contribution selection by simulation of fifty breeding …

Molecular Electronic Structure via Photoelectron Imaging Spectroscopy
… distributions. Experimental ion generation, mass selection, laser photodetachment, and photoelectron ion imaging were all done in a photoelectron imaging spectrometer described in detail. Results from simplistic systems, OH- and CH-, are used to illustrate the general and fundamental …

Evaluation of resistance to Sclerotinia crown and stem rot caused by Sclerotinia trifoliorum in selected alfalfa cultivars
… technique may act as the primary step in the selection of disease resistant germplasm for propagation, re-evaluation, and mass selection before field testing.

Advances in Amino Acid Analysis for Marine Related Matrices and Its Application to Coastal Shelf Settings in The Canadian Arctic
… acids. Combining ion pairing separation and mass selection software with liquid chromatography tandem mass spectrometry (LC/MS/MS) allows detection of amino acids that were previously difficult to measure due to coelution and incomplete derivatization. The method was validated by examining a …

Instrumentation and contrast mechanisms in scanning helium microscopy
… of a solenoidal ioniser, magnetic sector for mass selection and finally a conversion dynode and electron multiplier for measuring the ion current. In chapter 5, the origins of the observed contrast in images from a scanning helium microscope are discussed. For rough surfaces, the helium atoms …

Photoelectron circular dichroism of anionic chiral metal complexes and deprotonated molecules
… using common table-top lasers. Furthermore, mass selection before photodetachment is possible such that electrons can clearly be assigned to a species of specific mass. Apart from experimental advantages, the impact of short-range interactions (e.g. dipole moment, scattering potential) …

EVALUATION OF PHARMACEUTICAL AND COSMETIC USE OF EXCIPIENTS OBTAINED FROM CITRUS PROCESSING WASTE PRODUCTS
… of such phytochemicals, the remaining biomasses can be further used to recover residual lipid traces that have not been investigated so far. This doctoral thesis aimed to investigate whether bergamot lipid components (BLCs) remaining in the bergamot discarded biomass could be a functional …

Breeding for resistance to clover rot (Sclerotinia spp.) in red clover breeding (Trifolium pratense)
… of clover rot resistance, we applied divergent selection by the high-throughput bio-test on an experimental population. Our high-throughput biotest altered the resistance level in both directions in the first generation of selection, but only marginal progress was made in the second generation. …
