ABSTRACT Most barley cultivars are resistant to stripe rust of wheat that is caused by Puccinia striiformis f. sp. tritici. The barley cv. Steptoe is susceptible to all identified races of P. striiformis f. sp. hordei (PSH), the barley stripe rust pathogen, but is resistant to most P. striiformis f. sp. tritici races. To determine inheritance of the Steptoe resistance to P. striiformis f. sp. t...

tion database for the barley accessions is vital to increasing the utility of the collection in choosing parents for Cultivated barley (Hordeum vulgare subsp. vulgare L.) accessions germplasm enhancement, in genetic diversity assessfrom the USDA-ARS National Small Grains Collection (NSGC) have been tested systematically for the past 20 yr for disease and insect ments, and as baseline data for g...

Atmospheric nitrogen biologically reduced in legumes root nodule and accumulated their postharvest residues may be of great importance as a source this macronutrient for succeeding crops. The aim the study was to determine uptake by winter triticale from pea residues, including N fixed atmosphere, using fertilizer enriched with 15N isotope. Triticale grown without fertilization at sites where f...

Pea is a temperate grain legume cultivated worldwide that can be severely constrained by powdery mildew infection. Control fungicides and the use of resistant cultivars possible, but there growing interest in alternative control methods such as crop diversification, particularly low input agriculture. The aim this work was to assess potential intercropping pea with other crops cultivar mixtures...

The article is devoted to the analysis of structure sown areas and characteristics barley varieties zoned in Kirov region for 2020. In 2019 cultivated production more than 20 years had largest specific weight – 50.1 % acreage occupied with barley. Those 10 36.1 %; from 5 13.8 %. Certified sowings varied year percentage area. There a gradual decrease unsorted 3.0 thousand hectares 2017 up 1.18 2...

effects of drought stress and chemical treatments was studied on growth and developmental traits of four barley cultivars using a split- split plot design (rcbd) in agricultural research farm, kerman university. main plots consisted of irrigation (control and drought stress after flowering), sub-plots consisted of four barley cultivars ( ʻnosratʼ, ʻafsalʼ, ʻyousofʼ and ʻuh12 lineʼ) and sub-sub ...

Barley yellow dwarf (BYD), the most common and widespread virus disease of cereal crops worldwide (14), may be caused by any one of several Barley yellow dwarf viruses (BYDVs) of the family Luteoviridae. Transmitted by at least 25 aphid species (24), these viruses historically have been classified into two subgroups and five strains based on aphid vector specificity and efficiency (31). However...

Plant disease resistance genes (R-genes) play a critical role in the defense response to pathogens. Barley is one of the most important cereal crops, having a genome recently made available, for which the diversity and evolution of R-genes are not well understood. The main objectives of this research were to conduct a genome-wide identification of barley Coiled-coil, Nucleotide-binding site, Le...
