Northern areas of the western United States are one of the most productive wheat growing regions in the United States. Increasing productivity through breeding is hindered by several biotic stresses which slow and constrain targeted yield improvement. In order to understand genetic variation for stripe rust (Puccinia striiformis f. sp. tritici), Septoria tritici blotch (Mycosphaerella graminico...
Preharvest sprouting (PHS) of durum wheat (Triticum turgidum ssp. durum (Desf.) Husn.) is an important problem in Japan, where the rainy season overlaps with the harvest season. Since there are few PHS-resistant genetic resources in durum wheat, we introduced an R-gene for red seeds, the MFT gene, and the QPhs-5AL QTL, all of which are associated with PHS resistance, into durum wheat from a PHS...
rived from Amigo have been recognized as the most favorable for yield (Lukaszewski, 1990; William and The confounding effect of wheat (Triticum aestivum L.) genetic Mujeeb-Kazi, 1993). T1BL·1RS resulted in higher grain background has been addressed as the major factor in inconsistent yield, kernel weight, and above-ground biomass (Carver agronomic performances of 1RS translocation. The objectiv...
heat stress is one of the main obstacles for crop production in many areas of the world including southwest of iran. in order to evaluation the effect of heat stress on yield, yield component, and mopho-phenological traits of wheat, an experiment was conducted during 2010-2011 under normal (optimum sowing date) and heat stress (late sowing date) conditions on 11 wheat genotypes including yavaro...
Breeding for solid-stemmed durum (Triticum turgidum L. var durum) and common wheat (Triticum aestivum L.) cultivars is one strategy to minimize yield losses caused by the wheat stem sawfly (Cephus cinctus Norton). Major stem-solidness QTL have been localized to the long arm of chromosome 3B in both wheat species, but it is unclear if these QTL span a common genetic interval. In this study, we h...
Aluminum is one of the most abundant elements in soil that become soluble form as Al+3 in high acidic soils, absorbed through the roots and affect on plants growth. Evaluating plant tolerance to environmental stresses in seedling stage is an important factor for selecting plant to cultivate in different conditions. In order to evaluate tolerance of 83 durum wheat advanced line at aluminum toxic...
Spectral reflectance indices can be used to estimate the water status of plants in a rapid, non-destructive manner. Water spectral indices were measured on wheat under a range of water-deficit conditions in field-based yield trials to establish their relationship with water relations parameters as well as available volumetric soil water (AVSW) to indicate soil water extraction patterns. Three t...
Increasing grain yield is the most important goal in any breeding program. Since yield is a complex trait and involves several quantitative components with low inheritance, its direct evaluation is not usually sufficient and therefore it is suggested that its components be investigated instead. The objective of this study was grouping 60 inbred lines along with four check cultivars of wheat fro...
This study was conducted to investigate the genetic diversity of bread wheat, durum wheat and triticale using agronomic and physiological traits. Genetic diversity of 24 genotypes was evaluated in 2 locations (Research Farm of College of Agriculture, Isfahan University of Technology, located at Lavark, Najaf-Abad and Asheghabad farm), Isfahan, Iran, using a randomized complete block design with...
In this study, we successfully introgressed and validated Yr59 into four elite wheat cultivars, Jimai 22, Chuanmai 42, Zhengmai 9023 Xinmai 26 through marker-assisted backcross selection. Used as female parents, these cultivars were crossed with line PI 660061 (Yr59). After two backcrosses selection, the progenies selfed advanced to BC2F4 generation. A total of 123 lines selected based on agron...
