Agronomic potential and physiological performance of synthetic hexaploid wheat-derived populations

Creator:: del Blanco, Isabel Alicia
Resource Type:: Dissertation

Performance of five winter wheat cultivars when grown in composite and pure stand populations under different environmental stresses

Creator:: Indelen, Erdogan
Abstract:: Five genetically and morphologically different winter wheat cultivars, Hyslop (H), Yamhill (Y), Paha (P), Luke (L), and Sprague (5) were blended in all possible combinations. These composites plus the five pure stands were planted in the fall of 1973 at three environmentally diverse locations in Oregon: Hyslop Agronomy Farm, Corvallis;...

A comparison of selected analyses for estimating environmental variation in early generations and advanced lines of wheat (Triticum aestivum L. em thell)

Creator:: Khan, Noor-ul Islam
Abstract:: This investigation was motivated by the introduction of the new nearest neighbour analyses which reportedly provided a better control of soil gradients than conventional experimental methods. Three nearest neighbour analyses and six other analyses were compared with the completely randomized design or the randomized complete block design in reducing the...

Pre-harvest sprouting tolerance of a synthetic hexaploid wheat (Triticum turgidum L. x Aegilops tauschii Coss.)

Creator:: Rosa, Andre Cunha
Abstract:: Pre-harvest sprouting in wheat costs farmers millions of dollars every year. Pre-harvest sprouting tolerance (PST) has minimized this problem, but improvement of PST is still necessary. Synthetic hexaploid wheats (synthetics) have been used as sources of genes coding for many useful traits. Two studies evaluated the PST of a synthetic...

A comparison of two methods of divergent mass selection for heading date in two winter wheat (Triticum aestivum L. em Thell) crosses

Creator:: Frederickson, Leslie John
Abstract:: Responses to two cycles of mass selection for heading date, followed by selfing or intermating, were studied in two diverse winter wheat (Triticum aestivum L. em. Thell) crosses. Selection was bidirectional, resulting in early and late populations for each mating system, cycle, and cross. The influence of mass selection for...

Possible compensations of the components of grain yeild in wheat (Triticum aestivum L.) as influenced by genotype by environment interactions

Creator:: Bedoshvili, David
Abstract:: Despite many investigations genotype by environment interaction remains one of the least understood factors in plant improvement. Understanding genotypic differences responsible for such interactions could assist in making more informed breeding decisions. The components of yield being less complex than grain yield per se may be useful for selection to...

Possible associations between three procedures to measure noodle starch quality in winter wheat (Triticum aestivum L.)

Creator:: Weight, Chris (Christopher Thompson)
Abstract:: Until recently, the viscoamylograph had been the primary method for measuring starch as it relates to noodle quality in wheat. This method requires a large sample of flour and is time consuming. With the introduction of the rapid visco-analyser (RVA) in 1986 and the more recent flour swelling volume procedure,...

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...

Interrelation of the components of grain yield in a cross between dwarf and semidwarf wheat (Triticum aestivum L.) cultivars

Creator:: Medina, Luis E.
Abstract:: Parents and progeny populations from a cross of 'Stephens'x 'Tibet dwarf' were grown in a spaced-planted experiment to obtain information concerning the nature of inheritance and possible associations between grain yield and the components of yield. Agronomic traits measured on an individual plant basis were: heading date, days to maturity,...
