Inheritance of resistance in some wheat introductions to selected races of bunt, Tilletia caries (DC) Tul and Tilletia foetida (Wallr) Liro

Creator:: Abdalla, Osman S.
Abstract:: Bunt or stinking smut is a major disease of wheat. In the U.S. common bunt, Tilletia caries (DC) Tul. and T. foetida (Wallr) Liro, is a threat to wheat production in the Pacific Northwest. Screening trials conducted by USDA Cereal Investigations Project in Oregon, from 1955-1980, revealed that a number...

Chemically induced male sterility and natural out-crossing in selected wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Ekse, Ali Osman
Abstract:: Three chemicals SD 55446, SD 55447 and WL 84245 were found to induce male sterility in cultivars of wheat or triticale. Both SD 55446 and SD 55447 when applied at a concentration of 0.896 kg/ha resulted in 90% male sterility. However, SD 55447 caused female sterility at the same concentration...

Assimilate production and partitioning in wheat

Creator:: Mkamanga, Godwin Yindoli
Abstract:: Studies on net carbon exchange, ¹⁴ C assimilation, and growth analysis were done on four cultivars of high yielding soft white winter wheat (Triticum aestivum L. em Thell), Anza/Sturdy, Hill- 81, Stephens, and Yamhill, which differ in morphology, maturity, and yield, to see if differences in production and distribution of...

Nitrogen timing and placement effects on grain and plant nitrogen, and grain yield in hard red winter wheat

Creator:: Bohle, Mylen G.
Abstract:: Hard red winter wheat has the potential to be an alternative crop in the Pacific Northwest, however percent grain nitrogen has been unacceptably low and grain yields have been about only 80% of soft white winter wheat. During the late spring and the summer months there is usually little rainfall,...

Quantitative resistance to Puccinia striiformis f. sp. hordei in barley near-isogenic (BISON) lines

Creator:: Richardson, Kelley L.
Abstract:: Quantitative resistance (QR) to disease is usually more durable than qualitative resistance, but its genetic basis is not well understood. We used the barley/barley stripe rust pathosystem as a model for the characterization of the QR phenotype and associated genomic regions. As an intermediate step in the preparation of near-isogenic...

Characterization of Triticum turgidum ssp. carthlicum (Nevski) Löve et Löve by discriminant analysis

Creator:: Vieira, Luiz Gonzaga E.
Abstract:: Forty-six morphological characters were used in a study of Triticum turgidum ssp. carthlicum (2n = 28) and specimens of carthlicum-like forms of Triticum aestivum ssp. vulgare (2n = 42). The morphological variation patterns within these groups were examined using stepwise discriminant analysis. These results indicate that specimens studied could be...

Estimates of genetic variability resulting from single, top, and double cross populations in durum wheat (Triticum turgidum L. var. durum)

Creator:: Abdennadher, Mourad
Abstract:: The success of a plant breeding program depends upon the availability of useable genetic diversity. Such diversity may be enhanced depending on the type of hybridization strategy employed. Segregating progenies resulting from F2 populations, a double cross, and a top cross were compared for the amount of useable genetic diversity...

Testing the effectiveness of barley stripe rust resistance QTL detected in Mexico and the USA against a possible new race in Peru and mapping of genes conferring resistance to leaf rust and mildew in the same population

Creator:: Rossi, Carlos
Abstract:: Barley is the fourth most important cereal crop in the world because of its broad adaptation, its utility as a feedstock and for human food, and the superior properties of barley malt for brewing. Three of the most important foliar diseases of barley, on a worldwide level are: barley leaf...

Assay of the trypsin inhibitor activity in seeds of triticale

Creator:: Yao, Tsui-Li
Abstract:: Triticale, a newly man-made cereal from a wheat-rye cross offers a unique food and feed potential because of its higher protein content with nutritionally balanced amino acid composition as compared to other cereal grains. However, some cereal proteins such as trypsin inhibitors, present in triticale and rye, can affect the...
