Genotype-environment interaction in winter wheat F₁ progeny

Creator:: Peterson, C. J.
Abstract:: Seven winter wheats were evaluated for plant height, the components of yield and yield in a diallel cross at Pendleton, Oregon and Lind, Washington. An additional parent was added to the diallel cross at Pullman, Washington. Two levels of nitrogen and five replications were utilized at each of the locations....

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...

Combining ability and associations of agronomic traits involving three sources of dwarfism in wheat (Triticum aestivum, L. em Thell)

Creator:: Maya de Leon, Jose Luis
Abstract:: Three genetically different dwarf cultivars of spring wheat were evaluated as potential sources of short stature to use in a wheat improvement program. The study involved a five parent diallel cross which included a semidwarf, a standard height and three dwarf cultivars. The genetic sources of dwarfism included a Norma...

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...

Potential reciprocal differences for selected traits in six different F₁ wheat populations

Creator:: Stein, Ira Steven
Abstract:: Concerns about the possible reciprocal differences resulting from systematic crossings of winter and spring wheat gene pools prompted this investigation. If traits can be improved by simply reversing the direction of a cross, then identification of the best female parent in a cross would be helpful for breeding programs. Two...

Heritability estimates and associations for protein content and grain yield involving four winter wheat crosses (Triticum aestivum Vill., Host)

Creator:: Solen, Polat
Abstract:: Four agronomically and genetically diverse winter wheat parents were utilized as the experimental organisms. Atlas 66 and NB 68513 were selected as cultivars with a high and stable protein content when grown under different environmental condidtions. They are intermediate for grain yield when grown in the Pacific Northwest. Yamhill and...

Pre-harvest sprouting tolerance of a synthetic hexaploid wheat (Triticum turgidum L. x Aegilops tauschii Coss.)

Creator:: Rosa, Andre Cunha
Abstract:: Pre-harvest sprouting in wheat costs farmers millions of dollars every year. Pre-harvest sprouting tolerance (PST) has minimized this problem, but improvement of PST is still necessary. Synthetic hexaploid wheats (synthetics) have been used as sources of genes coding for many useful traits. Two studies evaluated the PST of a synthetic...

Evaluation of early generation testing in a diallel cross involving four winter wheat cultivars (Triticum aestivum Vill., host)

Creator:: Daaloul, Abderrazak
Abstract:: Factors which influence the effectiveness of making early generation selections within bulk populations were investigated. Material utilized included the parents, F₁, and F₂ through F₅ bulk populations resulting from a diallel cross. Information concerning the response of two traits, plant height and grain yield, was obtained for these populations at...
