1998 OUTLOOK OF THE U.S. AND WORLD WHEAT INDUSTRIES AgEcon
Koo, Won W.; Taylor, Richard D..
This report evaluates the U.S. and world wheat markets for the 1997-2007 period by using the World Wheat Policy Simulation Model. This analysis is based on a series of assumptions about general economic conditions, agricultural policies, the weather, and technological change. Both the U.S. and world wheat economies are predicted to be optimistic for the next ten years. World demands for both common and durum wheat are expected to grow faster than world production of the two wheat classes, resulting in gradual increases in prices of the wheats. World trade volumes of both classes of wheat are expected to expand, but trade volume of durum wheat may grow faster than common wheat.

A comparison between Joint Regression Analysis and the Additive Main and Multiplicative Interaction model: the robustness with increasing amounts of missing data Scientia Agricola
Rodrigues,Paulo Canas; Pereira,Dulce Gamito Santinhos; Mexia,João Tiago.
This paper joins the main properties of joint regression analysis (JRA), a model based on the Finlay-Wilkinson regression to analyse multi-environment trials, and of the additive main effects and multiplicative interaction (AMMI) model. The study compares JRA and AMMI with particular focus on robustness with increasing amounts of randomly selected missing data. The application is made using a data set from a breeding program of durum wheat (Triticum turgidum L., Durum Group) conducted in Portugal. The results of the two models result in similar dominant cultivars (JRA) and winner of mega-environments (AMMI) for the same environments. However, JRA had more stable results with the increase in the incidence rates of missing values.

ECONOMIC ANALYSIS OF THE PROPOSED NORTH DAKOTA WHEAT POOL AgEcon
Koo, Won W.; Nganje, William E.; Johnson, D. Demcey; Park, Joon J.; Taylor, Richard D..
The ND Durum Wheat Pool may provide additional revenue to durum wheat producers by raising the domestic prices in the North American market with full cooperation from the Canadian Wheat Board. The pool also could provide additional revenue to its members by improving marketing efficiency. On the other hand, the ND Spring Wheat Pool is less likely to provide additional revenue to spring wheat producers by raising domestic prices, mainly because hard red spring and winter wheat are highly substitutable. Efficiency gains also could be smaller than for durum wheat.

Effect of soil depth and increasing fertilization rate on yield and its components of two durum wheat varieties Chilean J. Agric. Res.
Hirzel,Juan; Matus,Iván.
Agronomic practices, climatic variables, and soil conditions are key factors in crop productivity. Although the effects of soil chemical properties and water and agronomic crop management are known, there is little information about effective soil depth and its influence on crop productivity. Since most crop fertilization systems are based on the productive potential associated with climatic conditions and chemical properties of the first 20 cm of soil depth, the objective of this study was to determine the importance of effective depth in terms of increasing fertilization rates on durum wheat (Triticum turgidum L. var. durum) productivity. Two experiments were conducted in the 2006-2007 season in the Santa Rosa Experimental Station (71°54' S, 36°31' W,...

Effect of Split Nitrogen Applications on Durum Wheat Cultivars in Volcanic Soil Chilean J. Agric. Res.
Hirzel,Juan; Matus,Iván; Madariaga,Ricardo.
Durum wheat (Triticum turgidum L. var. durum) is an important crop for the world population and occupies a large cultivated area worldwide. New cultivars need constant improvement of their agronomic management, within which N fertilization is highlighted. Durum wheat is also important in Chile where genetic breeding and agronomic management have been developed to increase yield, industrial, and nutritional grain quality. The objective of this experiment was to determine the appropriate number of N applications during a crop cycle in a volcanic ash soil in South Central Chile. Nitrogen split applications were carried out on three durum wheat cultivars in a Melanoxerands soil during the 2003-2004 and 2004-2005 seasons. A rate of 200 kg ha-1 N was applied at...

Genetic variation and interrelationships of agronomic characteristics in durum wheat under two constructing water regimes BABT
Talebi,Reza; Fayyaz,Farzad; Naji,Amir Mohammad.
This work aimed to study the grain yield components and plant characteristics related to grain yield. Twenty-four durum wheat genotypes from the ICARDA durum wheat breeding program were grown during 2006-2007 under rainfed and irrigated conditions using a complete randomized block design with three replicate in west of Iran. Correlation and path analysis were carried out. Results showed that there was strong positive association of grain yield with the number of seed/spike, biomass and harvest index. Grain yield was negatively associated with spike length and plant height in different moisture conditions. Comparatively, high genetic variation was found in grain yield and other characteristics. Hierarchical cluster analysis was used as a tool to classify...

Improving durum wheat (Triticum turgidum L. var durum) grain yellow pigment content through plant breeding Ciencia e Investigación Agraria
Schulthess,Albert; Schwember,Andrés R.
A. Schulthess, and A.R. Schwember. 2013. Improving durum wheat (Triticum turgidum L. var durum) grain yellow pigment content through plant breeding. Cien Inv. 40(3): 475-490. Wheat grain yellow pigment content (GYPC) is an important trait that determines pasta quality. The main objective of this review is to examine the genetics regulating GYPC to enhance it through breeding, leading to improved pasta quality. Although GYPC is a polygenic trait, its high heritability has facilitated breeding internationally. GYPC is influenced by one or two major loci with additive effects plus several minor genes, and there is evidence showing that the phytoene synthase loci PSY1A and PSY1B are strong candidate genes that regulate GYPC. Nine Chilean durum wheat (Triticum...

Lleuque-INIA, New High Yield Spring Durum Wheat Variety for Chile Chilean J. Agric. Res.
Matus,Iván; Madariaga,Ricardo; Alfaro,Christian; Jobet,Claudio.
The Lleuque-INIA spring durum wheat variety (Triticum turgidum var. durum L.) originated from a cross carried out by the Instituto de Investigaciones Agropecuarias (INIA), National Wheat Program, in the Centro Regional de Investigación La Platina, Santiago, Chile, in 1993. This variety has an upright growth habit in the seedling stage; the adult plant is of medium height and varies between 80 and 90 cm. The spike is medium-sized, white, and exhibits long whitish awns along its full length. The grain is large-sized, elongated, golden yellow, and vitreous. The variety was sown in mid-August in the Santa Rosa Experimental Station (36°31’ S; 71°54’ W), Chillán, head emergence occurred between 89 and 91 d after sowing, and was 6 to 8 d later than ‘Llareta-INIA’...
