Estimates of heterosis in winter/winter, winter/spring, and spring/spring crosses of barley (Hordeum vulgare L.)

Creator:

Oakley, Stephen Roland

Abstract:

Previous work indicated a substantial heterotic expression for grain yield existed within winter/spring hybrids of barley, This research was a continuation for the comparison of the expression of heterosis within winter/spring hybrids to the heterotic effect produced among the winter and among the spring parents. The F₁ and F₂ progenies...

The effect of fertility level on plant growth and development, water uptake and water stress in dryland wheat production

Creator:

Agamennoni, Raul Jose

Abstract:

Dryland winter wheat in eastern Oregon is usually subjected to water stress several times during the growing period. Moreover, the last three months of growth period depend strongly on the available soil water. The fertility level, stage of growth, availability of soil water and climatic conditions all interact to determine...

Yield loss assessment in nonprotected winter wheat varieties (Triticum aestivum, L. em Thell)

Creator:

Camacho Casas, Miguel Alfonso

Abstract:

The effects of some soil- and foliar-borne biotic factors on grain yield and the components of yield were evaluated using five winter wheat varieties sown at two dates. Within each planting date, varieties were grown under four different combinations of two soil treatments (fumigation and nonfumigation) and two foliar treatments...

A comparison of three systems of phenotypic selection for grain yield in three spring barley populations

Creator:

Hayes, Patrick M.

Abstract:

Concerns regarding the most effective means of evaluating segregating generations of spring barley prompted this investigation. Three methods of selection were considered: bulk, pedigree, and single seed descent. F₆ lines derived by each method were grown in a replicated yield trial. The effectiveness of each method was measured in terms...

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...

Factors influencing metribuzin use in strip-planted wheat

Creator:

Zeghida, Ali

Abstract:

Equipment for strip-till planting is under development in wheat-fallow rotations in the Columbia Basin of Oregon. This involves the absence of tillage during the fallow season. At planting time, the strip-till planter creates a narrow band into which the wheat seed is placed. The area between the rows is undisturbed...

Prediction of kernel hardness and grain protein based on the performance of F₃ and F₄ populations derived from ten wheat crosses (Triticum aestivum L. em Thell)

Creator:

Hazar, Necati

Abstract:

Ten wheat crosses (four winter x spring and six winter x winter) involving F₃ and F₄ generations and their respective winter parents were used to determine whether the early generation selection would be effective for kernel hardness and grain protein content. In 1980, twenty individual F₂ plants were selected with...

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...

Inheritance and association of earliness and grain yield in four winter x spring wheat crosses (Triticum aestivum L. em Thell.)

Creator:

Firat, Ahmet Ertug

Abstract:

Parental and segregating populations derived from four winter x spring wheat crosses were investigated to obtain information concerning the inheritance and association of earliness, grain yield and yieldrelated traits. Feasibility of selecting in early generations for these characteristics was also evaluated. Four winter wheat cultivars (Hyslop, Yamhill, Bezostaia 1, and...

Duration and rate of the grain filling period and subsequent grain yield in crosses between facultative and winter wheat cultivars (Triticum aestivum L. em Thell)

Creator:

Mou, Beiquan

Abstract:

Concerns about the genetic control and environmental influence of various stages of development including the grain filling period, and the relationship between early maturity and grain yield prompted this study. The experimental material consisted of two facultative and two winter wheat cultivars. A dial!el cross, excluding reciprocals, was also developed...
