Cultivated barley, Hordeum vulgare L., is considered to be a nonhost or intermediate host species for the wheat leaf rust fungus Puccinia triticina. Here, we have investigated, at the microscopic and molecular levels, the reaction of barley cultivars to wheat leaf rust infection. In the nonhost resistant cultivar Cebada Capa, abortion of fungal growth occurred at both pre- and posthaustorial st...

ninety barley doubled haploid lines originated from crossing between six barley cultivars in cereal research department, seed and plant improvement institute, karaj, iran were evaluated for resistance to powdery mildew and some agronomic traits in field in 2007. six parent cultivars and a powdery mildew susceptible check cultivar, afzal were also included. sixty two doubled haploid lines showed...

Barley powdery mildew, Blumeria graminis f. sp. hordei (Bgh), is an obligate biotrophic ascomycete fungal pathogen that can grow and reproduce only on living cells of wild or domesticated barley (Hordeum sp.). Domestication and deployment of resistant barley cultivars by humans selected for amplification of Bgh isolates with different virulence combinations. We sequenced the genomes of two Euro...

The effector protein NIP1 from the barley (Hordeum vulgare) pathogen Rhynchosporium secalis specifically induces the synthesis of defense-related proteins in cultivars of barley expressing the complementary resistance gene, Rrs1. In addition, it stimulates the activity of the barley plasma membrane H(+)-ATPase in a genotype-unspecific manner and it induces necrotic lesions in leaf tissues of ba...

Eleven winter barley cultivars from Palestine screened for their resistance to powdery mildew in the field and under controlled conditions while, two types of resistance were identified. Three accessions showed low infection type (IT) at seedling stage with low disease severity (DS) in the mature plant. Six other lines showed low DS and low infection frequency (IF) with no macroscopically visib...

Aluminium (Al) toxicity is an important limitation to barley (Hordeum vulgare L.) on acid soil. Al-resistant cultivars of barley detoxify Al externally by secreting citrate from the roots. To link the genetics and physiology of Al resistance in barley, genes controlling Al resistance and Al-activated secretion of citrate were mapped. An analysis of Al-induced root growth inhibition from 100 F2 ...

Barley next to wheat is the most important and widely adapted food cereal in the lower parts of Karkhe River Basin. This crop is one of the most salt-tolerant crop species. Varieties of the crop differ considerably in their ability to tolerate salinity. These differences can be used for selecting high yielding varieties under saline conditions. A field experiment was conducted in Dasht-e Azadeg...

line yesevi-93 (cultivar abidar) was first introduced to dryland agricultural research institute (dari) through the international winter preliminary barley yield trials (iwpbyt) in 1994. it was selected as one the most high yielding lines based on observational and statistical trails (regional barley yield trials) carried out in different locations during 1997-2000. the average yield of abidar ...
