Cultivar type, plant population, and ascochyta blight in chickpea
Integrated management strategies are required to minimize ascochyta blight, a fungal disease caused by Ascochyta rabiei (Pass.) Labrousse [teleomorph, Didymella rabiei (Kovachevski) v. Arx] in chickpea (Cicer arietinum L.). This study determined the effect of cultivars varying in plant architecture and plant population density (PPD) on the severity of ascochyta blight. Four desi chickpea (with ...

The Spirit Level, economic democracy and health inequalities
'The Spirit Level' by Wilkinson and Pickett (2009) provides a serious critique of inequality and how it blights the lives of many people in high-income countries. Unfolding in two main sections, this paper initially outlines Wilkinson's thesis generally before focusing and initiating a debate on Wilkinson and Pickett's suggestion of economic democracy (increased employee control and ...

Effects of planting pattern and fungicide application systems on ascochyta blight control and seed yield in chickpea
Improved cultural practices can be used to manage ascochyta blight in chickpea (Cicer arietinum L.), a disease caused by Ascochyta rabiei (Pass.) Labrousse. This study examined the effect of planting pattern, seeding rate, and fungicide application systems on ascochyta blight severity and crop yield of chickpea at Swift Current (50°25' N, 107° 44' W), SK, Canada, in 2004 and 2005. Crop was grown ...

Case study - Back Sand Point
As part of the £3.5 million hazardous landfill restoration project at involving 250,000 tonnes of restoration material we were contracted by local firm KLR to hydroseed over 100,000m2 in two stages using an Emorsgate wildflower seed mixture. In addition to the hydroseeding works, we also planted over 6,000 bare root trees and shrubs across the site, helping transform the once blighted land ...

Genetic mapping of sheath blight resistance QTLS within tropical Japonica rice cultivars
Most commercial cultivars of rice (Oryza sativa L.) are susceptible to sheath blight (SB), a devastating fungal disease causing significant losses in grain yield and quality. There are limited sources of genetic resistance adapted to U.S. growing conditions, and no commercial long grain cultivar of rice is currently available in the United States with a high level of SB resistance. Sheath blight ...

Ancestral landraces of common bean from the South of Europe and their agronomical value for breeding programs
Selection among breeding lines has been widely used to identify important cultivars and favorable alleles for adaptation, and resistance to abiotic and biotic stress. The objective of this work was to study the variability among common bean breeding lines selected from ancestral landraces, to evaluate the reaction of these lines to anthracnose (ANT) rust, common bacterial blight (CBB), halo ...

Effect of dwarfing Rht genes on Fusarium head blight resistance in two sets of near-isogenic lines of wheat and check cultivars
Reduced height (Rht) genes are used in wheat (Triticum aestivum L.) breeding throughout the world. Fusarium head blight (FHB) is one of the most destructive wheat diseases caused by Fusarium graminearum (Schwabe) and F. culmorum (W.G. Sm.) Sacc. Objectives of this study were to analyze the effects of (i) specific Rht dwarfing genes on FHB reaction using two sets of near-isogenic lines (NILs) and ...

Meta-analysis of QTL associated with fusarium head blight resistance in wheat
Quantitative trait loci (QTL) associated with resistance to Fusarium head blight (FHB), which is mainly caused by Fusarium graminearum Schwabe [telomorph: Gibberella zeae Schw. (Petch)], have been identified in wheat (Triticum aestivum L.) from different countries. Due to the differences of genetic backgrounds and analysis methods, the linked marker and significance levels of QTL are not ...

Spring wheat and durum yield and disease responses to copper fertilization of mineral soils
Copper deficiency has been linked to the incidence of a number of wheat diseases. Canadian research on mineral soils has suggested that low Cu availability, as indicated in a DTPA extraction soil test, combined with low soil organic C and coarse textures may also result in Cu deficiency of cereals. The objective of this study was to determine the yield responses of spring wheat (Triticum aestivum ...

Characterization of resistance to fusarium head blight in an eastern U.S. soft red winter wheat population
Host resistance is important to control Fusarium head blight (FHB) ), caused by the fungus Fusarium graminearum (Schwabe) [teleomorph: Gibberella zeae (schw.) Petch], in wheat (Triticum aestivum L.). Effective breeding requires understanding the genetics of resistance in breeding populations. Our objective was to deduce the genetics of FHB resistance in eastern U.S. soft red winter wheat (SRWW) ...

Resistance to fusarium head blight and kernel damage in a winter wheat recombinant inbred line population
Fusarium head blight (FHB), primarily caused by Fusarium graminearum Schwabe [teleomorph: Gibberella zeae (Schwein.) Petch], is a devastating disease of wheat (Triticum aestivum L.), causing low yields and poor quality kernels that may be contaminated by the mycotoxin deoxynivalenol (DON). The objective of this study was to examine kernel damage resistance and to map quantitative trait loci (QTL) ...

Tagging and mapping Pse-1 gene for resistance to halo blight in common bean differential cultivar UI-3
Halo blight [caused by Pseudomonas syringae pv. phaseolicola (Burkh.) Young et al. (Psp)] is a serious seed-borne bacterial disease of common bean (Phaseolus vulgaris L.). A few resistance (R) genes and quantitative trait loci provide control to one or more races of the pathogen. To better understand monogenic resistance and improve breeding efficiency, we sought to tag and map a gene (Pse-1) in ...

Construction of an intraspecific linkage map and QTL analysis for earliness and plant height in Lentil
Earliness and plant height traits are key targets in lentil (Lens culinaris Medikus) breeding and are quantitatively controlled. Recombinant inbred lines (RILs) are useful in genetic mapping studies of quantitative traits. The objectives of this study are to develop a genetic map and identify genome regions associated with earliness and plant height using RILs derived from a cross between ‘Eston’ ...

Identification of QTL conferring resistance to fusarium head blight resistance in the breeding line c93-3230-24
Control of Fusarium head blight (FHB), incited primarily by Fusarium graminearum Schwabe [telomorph Gibberella zea (Schwein)], has been a challenge for barley (Hordeum vulgare L.) producers in the upper midwestern United States for more than a decade. This disease manifests primarily in the form of food safety issues and quality discounts due to the presence of deoxynivalenol (DON), a mycotoxin ...

Molecular genetics of pathogenic oomycetes
Parasitic and pathogenic lifestyles have evolved repeatedly in eukaryotes (93). Several parasitic eukaryotes represent deep phylogenetic lineages, suggesting that they feature unique molecular processes for infecting their hosts. One such group is formed by the oomycetes. Traditionally, due to their filamentous growth habit, oomycetes have been classified in the kingdom Fungi. However, modern ...

Comparative mycotoxin profiles of gibberella zeae populations from barley, wheat, potatoes, and sugar beets
Gibberella zeae is one of the most devastating pathogens of barley and wheat in the United States. The fungus also infects noncereal crops, such as potatoes and sugar beets, and the genetic relationships among barley, wheat, potato, and sugar beet isolates indicate high levels of similarity. However, little is known about the toxigenic potential of G. zeae isolates from potatoes and sugar ...

Application of Agricultural Biotechnology for High Nutritious Food Products
Abstract Agricultural biotechnology has some controversy impacts on global economy and international regulations. But, it has enhanced the production of crops and foods with high nutritious. Some time, it has not secured human and environmental safety, intellectual property rights, consumer choice, ethics, food security, poverty reduction and environmental conservation. Even though, it has ...

Modern Miracles
When a technology comes along that unlocks a new way of thinking about an old problem, we marvel at it as a “modern miracle.” Growing up in Ireland, I know that memories of the Great Potato Famine still run deep. Today, Irish farmers know how fungicides have helped ensure that potato late blight remains a distant memory. Agriculture has come a long way since the nineteenth century, ...
