Genetic variability and association between agronomic and quality characteristics in twenty-nine female genotypes of Humulus lupulus L.

Creator:: Roberts, Donald Day
Abstract:: The genetic variability in and association between 14 traits that affect maturity, yield, and chemical properties of its product. The plant characters measured were: vigor, flowering date, harvest date, yield, lateral length, nodes per lateral, cones per lateral, cones per vine, cone weight. Alpha-acid and beta-acid content of the cone,...

Influence of different nitrogen and moisture levels on the expression of grain yield and protein content in selected wheat (Triticum aestivum, L. em Thell) and barley (Hordeum vulagre, L. em Lam.) cultivars

Creator:: Gomez-Pando, Luz
Abstract:: This investigation was conducted to provide information regarding 1) the relationship between the nitrogen percentage in the vegetative tissue of wheat and barley at various growth stages with grain protein and 2) to evaluate the possible association between grain yield and grain protein as influenced by different cultivars, nitrogen levels...

Evaluation of parental performance for grain yield in two populations of wheat (Triticum aestivum Vill., Host)

Creator:: Alcala de Stefano, Maximino
Abstract:: Six winter wheat cultivars were evaluated for their breeding value in transmitting superior genetic factors for grain yield to subsequent progeny. The cultivars were selected on the basis of their potential grain yield and divided into two populations. Population I was comprised of three cultivars which have been in commercial...

Inheritance of Septoria leaf blotch resistance and the possible influence of heading date and plant height on the disease expression in a winter wheat cross

Creator:: Camacho Casas, Miguel Alfonso
Abstract:: Parental lines, Fi's and segregating populations (F₂, F₃ and BC's) including reciprocals were evaluated under field conditions to determine if genetic resistance per se exists for Septoria Leaf Blotch in a selected winter wheat cross. The experiment was conducted over a three year period with both natural infection and artificial...

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...

Assessment of resistance and inheritance to Barley Yellow Dwarf Virus disease (BYDV) in five wheat cultivars (Triticum aestivum L.)

Creator:: Tola, Jaime
Abstract:: Barley Yellow Dwarf Virus (BYDV) is a major disease of wheat. Unfortunately, unlike barley where the Yd2 gene provides adequate levels of resistance, the situation in wheat is more complex. This study was designed to provide information regarding: 1) evaluation of methods of measuring resistance among selected cultivars; 2) identification...

Duration and rate of grain filling and subsequent grain protein content in selected winter wheat populations

Creator:: Mou, Beiquan
Abstract:: The lack of information regarding the inheritance of the duration and rate of grain filling, and the possible relationship between grain fill and grain protein content in wheat prompted this study. Early maturing Chinese cultivars, 'AI Feng 2' and 'CB 83-52', and late maturing cultivars adapted to Oregon, 'Stephens' and...

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...

Effect of row spacings, seeding rates and nitrogen fertilizer rates on the agronomic performance of Yamhill and Hysolop wheat (Triticum aestivum L.)

Creator:: Chemli, Mohamed
Abstract:: The response of two newly released cultivars of winter wheat when grown under different row spacings, seeding rates and nitrogen levels were investigated. Measurements made included grain yield, tiller number per unit area, plant height, 300 kernel weight, bushel weight and protein content of the grain. Hyslop and Yamhill cultivars...

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...
