selection tolerant cultivars of wheat (as a strategic plant) under drought stress by using traits that are less affected by the environment, increases efficiencies. In this regard, in order to study some genetic parameters of physiological and agronomical traits and also genetic diversity in spring wheat cultivars under normal irrigation (control) and drought stress conditions in booting stage,...
Journal of Plant Registrations, Vol. 3, No. 3, September 2009 279 Stripe rust (Puccinia striiformis Westend f. sp. tritici) is a major disease threat of spring wheat (Triticum aestivum L.) grown in the Pacifi c Northwest region of the United States. Few soft white spring wheat cultivars currently in commercial production have adequate levels of stripe rust resistance to prevent the need for fun...
Fusarium head blight (FHB), caused by Fusarium graminearum, is a very important disease of wheat globally. Damage caused by F. graminearum includes reduced grain yield, reduced grain functional quality, and results in the presence of the trichothecene mycotoxin deoxynivalenol in Fusarium-damaged kernels. The development of FHB resistant wheat cultivars is an important component of integrated ma...
For evaluation of the reaction twenty of spring wheat cultivars under complete irrigation (control) and drought stress condition starting before booting stage, an experiment was conducted in split plot basis of Randomized Complete Block Design with 4 replications in two cropping years (2010-2011 and 2011-2012) in research farm of Agriculture Faculty, University of Tabriz. The results of varianc...
In order to evaluation of morphological selection criteria for salt tolerance screening in wheat (T. aestivum L.) a factorial experiment based on completely randomized design in 3 replications were conducted under greenhouse condition. Salinity treatments involved 4 levels: S=1.3dSm-1 (control), 5, 10, 15 dSm-1 from calcium chloride and sodium chloride with 10:1 (Na: Ca ratio) and another facto...
in order to study of barely and wheat cultivars tolerance to metribuzin, a factorial experiment was conducted as a completely randomized design, with three replications in greenhouse of agricultural research at ferdowsi university of mashhad. treatments included wheat cultivars (backcross roshan, cross arvand, bahar, sepahan, gascosion, sayonez, bam garmsiry, garmsiri, ghods, pishtaz, chamran a...
Wheat Grain and Forage Yields are Affected by Planting and Harvest Dates in the Central Great Plains
cultivars, net return is maximized when grazing is terminated at first hollow stem—the stage at which hollow Although grazing of winter wheat (Triticum aestivum L.) is a stem can first be identified above the crown (Redmon common practice in the southern Great Plains, little is known about the efficacy of wheat as a dual-purpose crop in the Nebraska Panhanet al., 1996). However, beyond an optim...
abstractbackground and objectives: all changes in the development stages of plants results in the change of one or more yield components and finally, the ultimate yield and manipulation of these periods means to create new possibilities for increasing yield. accordingly, planting date has a significant impact on plant growth and development during the growth season, so that any shift in plantin...
Metaphase I (MI) pairing of wheat homologous chromosomes is usually reduced in hybrids between cultivars relative to the parental inbred lines. Previous work suggested that this phenomenon is caused by polymorphism in nucleotide sequences (nonstructural chromosome variation) among wheat cultivars. The present work investigated the distribution of this variation along three selected chromosome a...
The Ppd-A1 genotype of 240 Japanese wheat cultivars and 40 foreign cultivars was determined using a PCR-based method. Among Japanese cultivars, only 12 cultivars, all of which were Hokkaido winter wheat, carried the Ppd-A1a allele, while this allele was not found in Hokkaido spring wheat cultivars or Tohoku-Kyushu cultivars. Cultivars with a photoperiod-insensitive allele headed 6.9-9.8 days ea...
