More or less similar diseases have been described from other parts of th...

fire blight is an important worldwide disease of pome fruits that control of which through antibiotics is particularly critical. in this case and in absence of another chemical methods, the biocontrol methods can be considered as the best alternative for control of fire blight. in this study efficacy of 5 isolates of antagonistic bacteria belongs to pseudomonas fluorescens and pantoea agglomera...

rots (Great Plains); seedling blight (Great Plains). Indian ricegrass {Oryzopsis hymenoides) : Seedling blight (far West) ; common root rot and crown rot (far West) ; rhizoctonia rot (scattered) ; snow molds (Pacific Northwest); seed rots (general); root necrosis and crown rots (far West). Kentucky bluegrass {Poa pratensis): Dollar spot (Northeast) ; brown patch (general); foot rot, Helminthosp...

Fire blight, caused by Erwinia amylovora (Ea), is a destructive disease of Malus (apple), Pyrus (pear) and some woody ornamentals in the rose family (Rosaceae). The goal of this project is to use a functional genomics approach to develop tools to breed fire blight resistant apples. Suppression subtractive hybridization (SSH) and cDNA-AFLP analysis were used to identify 650 expressed sequence ta...

Interval mapping of quantitative trait loci (QTL) for resistance to late blight, height, and maturity was performed on a tetraploid full-sib family of potato comprising 227 clones from a cross between a susceptible parent, 12601ab1, and a resistant cultivar, Stirling, which were of similar height and main crop maturity. Thirty-eight AFLP primer combinations provided 585 informative markers, and...

foliar late blight resistance in other populations (Collins et al., 1999; Sandbrink et al., 2000). Association between A diploid Solanum population was developed with the objective QTL conferring foliar late blight resistance, tuberizaof mapping quantitative trait loci (QTL) associated with resistance tion, and vine maturity was found in four out of five to Phytophthora infestans (Mont.) de Bar...

Ascochyta blight is one of the major diseases of chickpea worldwide. The genetic resistance to ascochyta blight in chickpea is complex and governed by multiple QTLs. However, the molecular mechanism of quantitative disease resistance to ascochyta blight and the genes underlying these QTLs are still unknown. Most often disease resistance is determined by resistance (R) genes. The most predominan...

Blight symptoms on pigeonpea were observed in alarming proportion since 2009 onwards in Andhra Pradesh state of India. Alternaria blight infected pigeonpea plants were collected from Andhra Pradesh state of India to isolate and characterize the pathogen. The isolate proved pathogenic on pigeonpea cultivar ICPL 87119. Genetic characteristics were analyzed based on the sequence of the rDNA-intern...

In a survey conducted in 1984 in Essex, Lambton, and Middlesex Counties of Ontario, Canada, greater incidences of head blight and greater concentrations of deoxynivalenol in grain were observed in fields of winter wheat planted after corn than in those planted after soybeans, barley, and mixed grains. Neither head blight nor deoxynivalenol level were correlated significantly with soil P, K, or ...

Fusarium head blight, one of the most destructive diseases of wheat (Triticum aestivum L.), results in significant economic losses from reduced grain yield and quality. In recent decades, the disease has been frequently recorded, especially under warm and wet climatic conditions. Genetic resistance has engaged plant breeders because the use of resistant cultivars is the most economical, effecti...
