The genetic relationships of A genomes of Triticum urartu (Au) and Triticum monococcum (Am) in polyploid wheats are explored and quantified by AFLP fingerprinting. Forty-one accessions of A-genome diploid wheats, 3 of AG-genome wheats, 19 of AB-genome wheats, 15 of ABD-genome wheats, and 1 of the D-genome donor Ae. tauschii have been analysed. Based on 7 AFLP primer combinations, 423 bands were...
Glutenins from II varIetIes of wheat representing the five different classes commonly grown in the United States were compared in terms of protein composition and sensitivity to salt precipitation. Gluten obtained from the different wheats varied from 8 to 10.5 % for soft wheats to about 9 to 11 % for hard wheats and 17 % for durums. Gliadinglutenin ratios were similar in all varieties investig...
Cereal Chem. 73(6):770-774 Analysis of different wheats and flours for vitamin B6 using water exin PN (0.9-2.7 nmol/g). Mean values (± standard deviations) were 5.0 ± tracts and reverse-phase high-performance liquid chromatography 1.8 nmol/g for total vitamin B6; 1.7 ± 0.5 nmol/g for PN; and 3.4 ± 1.8 revealed significant variation in content of pyridoxine (PN) and pyrinmollg for PNG. American ...
We examined three different-ploidy wheat species to elucidate the development of aboveground architecture and its domesticated mechanism under environment-controlled field conditions. Architecture parameters including leaf, stem, spike and canopy morphology were measured together with biomass allocation, leaf net photosynthetic rate and instantaneous water use efficiency (WUE(i)). Canopy biomas...
BACKGROUND Synthetic hexaploid wheats are artificially reconstituted hexaploid wheats that possess high genetic variation which could be utilized for the development of new improved wheat varieties. One such group of synthetic wheats is called the Elite-II set of synthetic wheats that are derived from crossing durum wheat with different Aegilops tauschii wheats. MATERIALS AND METHODS In the c...
An experiment was conducted to examine the digestible energy (DE) content for weanling pigs in a cohort of wheats grown in Western Australia, and to establish relationships between DE content and their chemical composition. The 3 ✕ 3 ✕ 2 factorial experiment examined the wheat variety (Arrino, Stiletto and Westonia), growing location (high, medium and low rainfall zone) and harvest year (1999 a...
A set of waxy (amylose-free) experimental spring wheats (Triticum aestivum L.) of diverse parentage were grown, along with two nonwaxy and two partial waxy check cultivars, at diverse North American cultural environments. Grain yield and functional attributes of derived flours were determined. Average grain yield of the waxy lines did not differ significantly from the average yield of the check...
Relationship of nitrogen (N) supply to nitrogen remobilization and leaf and grain P, K, and N status of wheat lacks clarity. The present pot experiment was conducted to evaluate nitrogen remobilization and leaf and grain P, K, and N status of ancient wheats of different ploidy levels in response to nitrogen. The experiment was carried out in Fall 2017-Spring 2018 at the Isfahan University of Te...
Protein electrophoretic profiles cast doubt upon the prevalent theory that the B genome of the polyploid wheats was derived from a species of Aegilops. They suggest, instead, that the wild tetraploid wheats comprise a complex, whose components were derived from various combinations of diploid Triticum types, which evidently include the B-genome type.
Ten Synthetic Hexaploid Wheats (SHWs) (2n = 6x = 42, AABBDD) were analyzed using 7 Randomly Amplified Polymorphic DNA (RAPD) primers to investigate the potential genetic diversity resided within the D-genome of common wheat. Total 190 fragments were amplified in which 141 were polymorphic showing 74 % of polymorphism. Polymorphism Information Content (PIC), Genetic Similarity (GS) Coefficient, ...
