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...

Competitive effect for grain yield of four cultivars in pure and mixed populations in wheat (Triticum aestivum Vill;, Host)

Creator:: Valencia-Villarreal, Jose Antonio
Abstract:: Concerns regarding maintaining wheat yield per hectare and extending the commercial life expectancy of cultivars grown in the Yaqui Valley of Mexico prompted this investigation. Four genetically diverse spring wheat cultivars were grown in pure stands and in all possible combinations at the Northwest Agricultural Research Center at Ciudad Obregon...

Possible association between dwarfing genes Rht₁ and Rht₂ and the reaction to Septoria tritici blotch in winter wheat (Triticum aestivum L. em Thell)

Creator:: Baltazar, Baltazar
Abstract:: Four isogenic lines possessing different combinations of height reducing genes Rht₁ and Rht₂ from 'Norin 10' were crossed to a short stature, early maturing, septoria susceptible cultivar identified as the 'Tibet Dwarf'. The isogenic lines originated from the backcross population of 'Itana'/3/'Norin 10'/'Brevor 14'//6*'Itana'. Parents, F₁ and F₂ generations provided...

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,...

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...

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,...

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...
