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...

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...

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...

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...

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...

Natural outcrossing in spaced planted F₂ populations and solid seeded advanced generations of wheat (Triticum aestivum L. em Thell)

Creator:: Boinnet, Jerry K. K.
Abstract:: This study was conducted to investigate the possible contamination of foreign pollen at different stages of a wheat breeding program. These included spaced planted F₂ segregating populations, replicated yield trials and seed multiplication. The experimental wheat materials consisted of four different F₂ populations, four cultivars and two experimental lines. Two...

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...

Identification and inheritance of factors influencing the rate and duration of grain fill in selected wheat populations, (Triticum aestivum L. em Thell)

Creator:: Chuhe, Chen
Abstract:: To study the grain filling traits in wheat, two winter cultivars and four spring cultivars were selected. The resulting Fl, F2, F3 and backcrosses were tested. The following measurements were made: a) Visual traits for physiological maturity (PM), b) Grain dry weight accumulation, c) Regression models for grain filling period,...

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...
