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...

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...

Kernel hardness, protein, and viscosity as predictors of udon-noodle quality

Creator:: Ruddenklau, Helle G.
Abstract:: The Asian noodle market is responsible for the increased volume of wheat imported to that region in recent years. Soft white wheat produced in the Pacific Northwest is mainly used for baked products, whereas an Australian wheat, Australian Standard White, is preferred for noodles. To enter this market soft white-wheat...

Chemically induced pollen supression and subsequent natural outcrossing in selected wheat cultivars (Tritcum aestivum L. en Thell)

Creator:: Lewis, Hal A.
Abstract:: Effective chemical control of pollination would provide an alternative to the cytoplasmic male-sterile system in hybrid wheat (Triticum aestivum L.) production. The objective of this study was to determine concentration, formulation, growth stage of application and genotypic effects on levels of induced pollen suppression and subsequent natural out-crossing from foliar...

Performance of cultivars, hybrids and composites of winter wheat (Triticum aestivum L. em Thell) grown at three locations

Creator:: Verges, Ruben P.
Abstract:: The objective of this study was to compare three genetically different groups of winter wheat for their grain yield. Experimental material consisted of parental lines grown in pure stands, hybrids, and 1:1 mixtures of the parental combinations. Three sites were employed to evaluate possible interactions between the different groups across...

Time and duration of growth stages and subsequent grain yield in selected wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Choi, Byung Han
Abstract:: The need to develop a shorter life cycle wheat cultivar which would be more adapted to multiple cropping systems prompted this study. Thus the following information was obtained. Greatest variations in developmental patterns were found in the stem elongation, booting, inflorescence emergence and anthesis for five winter and five spring...

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...

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...

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...

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...
