Compensating effects and gene action estimates for the components of grain yield in winter wheat (Triticum aestivum, L. em Thell)

Creator:: Abi-Antoun, Michel
Abstract:: Five winter wheat cultivars and their diallel crosses were evaluated for plant height, harvest index, deading-maturity duration, the components of yield, (spikes per plant, spikelets per spike, kernel weight and kernels per spikelet)and total plant yield. Two diverse locations, Moro, a dryland site (250 mm annually) located in central Oregon...

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...

Combining ability and gene action estimates and the association of the components of yield in winter wheat crosses

Creator:: Kronstad, Warren E. (Warren Ervind), 1932-
Abstract:: A diallel cross consisting of ten parents was grown on the Hyslop Agronomy Farm near Corvallis, Oregon, in order to obtain estimates of the gene action contributing to yield and its components in wheat. Gene action estimates were obtained by two methods of diallel analysis and from narrow sense heritability...

Yield and other agronomic characters of winter wheat cultivars as affected by five seeding rates and three different environmental conditions

Creator:: Güler, Mengü
Abstract:: Five newly released and two Eastern European winter wheat cultivars were grown under five different seeding rates (80, 160, 240, 320, 400 seeds per m²). Four of these newly released cultivars were grown at three different locations which have different environmental conditions. Data were obtained on grain yield, tiller number...

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...

The effect of row spacing, rate and date of planting on yield and yield components of four winter wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Nadjib, Benacef
Abstract:: Four winter wheat cultivars, Bezostaya, Maris-Hobbit, Roussalka and Stephens, selected on the basis of the diversity of their pedigree and phenotype, were planted at Hyslop Experiment Station near Corvallis in Western Oregon to study their performance at three different row spacings (10, 16 and 24 cm), three seeding rates (100,...

Effects of irrigation frequency on yields of winter wheat

Creator:: Nakamura, Brian Clifford
Abstract:: Deliberately underirrigating a crop may yield economic benefits. The optimal use of water by an irrigator should be achieved under a deficit irrigation regime. It is important to know how water deficits affect yields and the interaction of the deficits with the scheduling of irrigations. A field experiment was conducted...

Adaptability of winter wheat cultivars to dryland conditions and their response to water stress

Creator:: Keim, Don Lee
Abstract:: Winter wheat cultivars (Triticum aestivum) were evaluated for their response to water stress and adaptability to a wide range of moisture limited environments. Grain yield was analyzed for ten cultivars at six locations across four years. Regression of the cultivar mean on the year-location mean was used as a measure...
