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...

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....

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...

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...

The influence of plant densities on gene action estimates and associations in seven winter wheat parents and their F₂ progeny

Creator:: Saini, Surinder Kumar
Abstract:: The F₂ progeny from a diallel cross involving seven winter wheat parents along with the parents were grown at the Hyslop Agronomy Farm near Corvallis, Oregon to determine the influence of three plant densities on gene action estimates for yield and its primary components. The plant densities were designed to...

Aluminum toxicity studies in rice (Oryza sativa L.)

Creator:: Martinez-Racines, Cesar P.
Abstract:: A nutrient solution technique developed for wheat was used to determine tolerance of rice cultivars to aluminum (Al) toxicity. Pre-germinated rice seed was placed on top of a screen and allowed to grow on the Al-free solution for 72-96 hours or until the primary root was 2-3 cms long. Seedlings...

Inheritance of plant height in barley (Hordeum vulgare L. Emed. LAM.)

Creator:: Bayraktar, Ali
Abstract:: Four, six-rowed, spring barley cultivars were used as parental material in this study. The parents were distinctly different in plant height. Washington-6124-62 is a standard height selection while Short Wocus and Minn. 66-102 are intermediate. The fourth parent was a dwarf selection obtained from India. The two intermediate cultivars and...

Possible associations between three procedures to measure noodle starch quality in winter wheat (Triticum aestivum L.)

Creator:: Weight, Chris (Christopher Thompson)
Abstract:: Until recently, the viscoamylograph had been the primary method for measuring starch as it relates to noodle quality in wheat. This method requires a large sample of flour and is time consuming. With the introduction of the rapid visco-analyser (RVA) in 1986 and the more recent flour swelling volume procedure,...

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...
