Drought stress is one of the leading constraints to wheat (Triticum aestivum L.) production globally. Breeding for drought tolerance using novel genetic resources is an important mitigation strategy. This study aimed to determine the level of drought tolerance among diverse bread wheat genotypes using agronomic traits and proline analyses and to establish correlation of proline content and agro...
Evaluation of Morpho-Physiological Diversity Durum Wheat Genotypes using Genotype x Trait Biplot Method
Early autumnal and late spring frosts usually impose damages to wheat production in North-West of Iran. In order to investigate cold tolerance of wheat genotypes, two laboratory and field experiments were carried out at three planting dates of 12 Oct. and 1 and 21 Nov. 2007 in Saatlu Agricultural Research Station on 15 genotypes with winter, facultative and spring-growth types. Arrangement of t...
Ordoñez, M. E., and Kolmer, J. A. 2009. Differentiation of molecular genotypes and virulence phenotypes of Puccinia triticina from common wheat in North America. Phytopathology 99:750-758. Wheat leaf rust caused by Puccinia triticina is widely distributed in the wheat growing regions of the United States and Canada, and is subject to selection for virulence phenotype by leaf rust resistance gen...
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...
Abstract Background Wheat straw, one of the most abundant agricultural residues worldwide, can be used to produce biogas, which is considered efficiently produced renewable energies. grown with dual-purpose producing food and biogas should display simultaneously high grain straw yields, low lodging susceptibility conversion efficiency into biogas. The aims this study were determine best food-fu...
The endopeptidase marker Ep-D1b and Sequence Tag Site (STS) marker XustSSR2001–7DL were reported to be closely associated with the most effective resistance gene (Pch1) in wheat (Triticum aestivum L.) for strawbreaker foot rot [Pseudocercosporella herpotrichoides (Fron) Deighton]. Our objectives were to: (i) develop an efficient assay method for Ep-D1b in wheat; (ii) correlate endopeptidase zym...
The selection of genotypes under high soil fertility may alter the effectiveness of mycorrhizal symbioses naturally forming between crop plants and the mycorrhizal fungi residing in cultivated fields. We tested the hypothesis that the mycorrhizal symbiosis of 5 landraces functions better than the mycorrhizal symbiosis of 27 cultivars of durum wheat that were bred after the development of the fe...
Durum wheat (Triticum turgidum L.), like most other crops, is affected by various stresses. Therefore, cultivars that, in addition to the ability to produce higher yields, can maintain their yield potential in different years and locations are considered superior cultivars. In order to obtain high-yielding and stable genotypes of durum wheat, 16 lines with two control cultivars Dehdasht and Sey...
Leaf rust of wheat, caused by Puccinia triticina, is a common and widespread disease in the Middle East. The objective of this study was to determine whether genetically differentiated groups of P. triticina are present in the Middle East region and to compare the population from the Middle East with the previously characterized population from Central Asia to determine whether genetically simi...
