Feasibility of developing bread wheat cultivars with acceptable protein content for non-traditional areas

Creator:: Lorenzo, Ariel
Abstract:: The objective of this investigation was to evaluate the possibility of developing high yielding wheat cultivars whose flour would result in acceptable loaf volumes for non-traditional bread wheat growing areas. Spring wheat germplasm employed included high protein hexaploid derivatives from Triticum dicoccoides, and selections from Argentina with good bread milling...

Aluminum toxicity studies in rice (Oryza sativa L.)

Creator:: Martinez-Racines, Cesar P.
Abstract:: A nutrient solution technique developed for wheat was used to determine tolerance of rice cultivars to aluminum (Al) toxicity. Pre-germinated rice seed was placed on top of a screen and allowed to grow on the Al-free solution for 72-96 hours or until the primary root was 2-3 cms long. Seedlings...

Nature of the inheritance of gluten strength and carotenoid pigment content in winter by spring and durum wheat crosses (Triticum turgidum L. Var. durum)

Creator:: Ammar, Karim
Abstract:: Durum wheat cultivars for North-Eastern Oregon have to be competitive in terms of their yield potential with soft white winter wheat cultivars and meet strict quality requirements of the milling industry. Combining the high yield potential of fall planted durum wheat cultivars which have an acceptable level of winter hardiness...

The expression of embryo maturation genes in wheat and the role of abscisic acid

Creator:: Berge-Chandler, Sonja Kay
Abstract:: A set of genes which show developmental and tissue specificity are expressed late in embryo maturation during grain formation in wheat (Triticum aestivum). Two members of this maturation gene set (MGS) are Em and triticin, a 7S globulin. Results presented here show that during embryogenesis, the expression of Em mRNA...

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...

The effects of tillage systems and seeding dates on grain yields of wheat (Triticum aestivum Vill., Host) on the Anatolian Plateau of Turkey

Creator:: Zinn, Thomas G.
Abstract:: Wheat (Triticum aestivum) is the major food crop produced on the Anatolian Plateau of Turkey where due to limited rainfall the farmers follow the traditional system of fallow farming. They are presently producing an average of 1.15 tons of grain per hectare during the crop year. This rate of production...

Effect of row spacings, seeding rates and nitrogen fertilizer rates on the agronomic performance of Yamhill and Hysolop wheat (Triticum aestivum L.)

Creator:: Chemli, Mohamed
Abstract:: The response of two newly released cultivars of winter wheat when grown under different row spacings, seeding rates and nitrogen levels were investigated. Measurements made included grain yield, tiller number per unit area, plant height, 300 kernel weight, bushel weight and protein content of the grain. Hyslop and Yamhill cultivars...

Inheritance of Septoria leaf blotch resistance and the possible influence of heading date and plant height on the disease expression in a winter wheat cross

Creator:: Camacho Casas, Miguel Alfonso
Abstract:: Parental lines, Fi's and segregating populations (F₂, F₃ and BC's) including reciprocals were evaluated under field conditions to determine if genetic resistance per se exists for Septoria Leaf Blotch in a selected winter wheat cross. The experiment was conducted over a three year period with both natural infection and artificial...

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...

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,...
