Ultrastructural study of the embryo during germination involving douglas fir (Pseudotsuga menseizii Franco) seeds

Creator:: Hsu, Kay Yong-Yong
Abstract:: The seeds of Douglas fir, a representative of the gymnosperm flora, were studied at six stages of germination to discern the structures of food reserves and to study ultrastructural changes occurring during germination in the embryo and resulting seedlings. The materials were fixed in three fixatives, dehydrated with ethanol series,...

The influence of plant densities on gene action estimates and associations in seven winter wheat parents and their F₂ progeny

Creator:: Saini, Surinder Kumar
Abstract:: The F₂ progeny from a diallel cross involving seven winter wheat parents along with the parents were grown at the Hyslop Agronomy Farm near Corvallis, Oregon to determine the influence of three plant densities on gene action estimates for yield and its primary components. The plant densities were designed to...

Evaluation of three methods of selection in relation to yield and yield stability in winter wheat (Triticum aestivum Vill., Host)

Creator:: Charoenwatana, Terd, 1937-
Abstract:: The effectiveness of early generation selection for yield and yield stability and the possible identification of superior parental combinations were studied in winter wheat populations representing different levels of genetic diversity. Experimental material for evaluating yield stability consisted of nine bulk and seven modified bulk populations derived from nine parental...

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

Evaluation of early generation testing in a diallel cross involving four winter wheat cultivars (Triticum aestivum Vill., host)

Creator:: Daaloul, Abderrazak
Abstract:: Factors which influence the effectiveness of making early generation selections within bulk populations were investigated. Material utilized included the parents, F₁, and F₂ through F₅ bulk populations resulting from a diallel cross. Information concerning the response of two traits, plant height and grain yield, was obtained for these populations at...

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...

Influence of population density on light interception and grain yield involving wheat hybrids

Creator:: Ganapathy, Mapangada Chengappa
Abstract:: Six wheat hybrids from two sets of parents and their respective parents were grown at Hyslop Agronomy Farm near Corvallis, Oregon in the year 1965-66. The object of the experiment was to evaluate the influence of population densities and different planting patterns on grain yield and factors which determine grain...

The inheritance of stem rust (Puccinia graminis graminicola) resistance in perennial ryegrass (Lolium perenne)

Creator:: Rose, Crystal A.
Abstract:: Three stem rust Puccinia graminis graminicola, resistant sources of perennial ryegrass, Lolium perenne, 4A, 48A, and 77A, were crossed in a partial diallel design with one susceptible source, MP-2, resulting in six crosses excluding reciprocals. The F1's and cloned parental populations were inoculated in the field and rated on a...

Durum wheat quality and its relation to electrophoretic banding patterns

Creator:: Encinas-Mungarro, Andrés
Abstract:: Physical properties of gluten and pigment content are of primary importance in determining quality in durum wheat (Triticum turqidum L. var. durum). The objective of this investigation was to evaluate the contribution of different -y-gliadin protein subunits in durum wheat pasta quality as measured by the sodium dodecyl sulphate microsedimentation...
