Genetic transformation of Ascochyta rabiei using Agrobacterium-mediated transformation
Current Genetics, 2005In order to study pathogenic mechanisms of the plant pathogen Ascochyta rabiei, conditions for efficient transformation using Agrobacterium-mediated transformation were investigated. Hygromycin B resistance (hph) was superior to geneticin resistance (nptII) for selecting transformants, and the hph gene was more efficiently expressed by the Aspergillus ...

Factors Affecting Growth, Sporulation, Pathogenicity, and Survival of Ascochyta Rabiei
Mycologia, 1973SUMMARYIsolates of Ascochyta rabici from diseased chickpea (Cicer arietinum) from India, Iran, Turkey, and West Pakistan varied greatly in growth rate, sporulation, and colony appearance.

Mode of Infection of Ascochyta Blight of Chickpea Caused by Ascochyta rabiei
Journal of Phytopathology, 1987AbstractProcess of infection and histological changes with Ascochyta blight of chickpea caused by A. rabiei (Pass.) Labr. were studied by light microscopy. Germ tubes from conidia of the fungus penetrate the stem tissue at the juncture of two epidermal cells and form subepidermal aggregates until the fourth day.

Development of the teleomorph of Ascochyta rabiei on culture media
European Journal of Plant Pathology, 2012Ascochyta blight caused by Didymella rabiei (anamorph: Ascochyta rabiei) is an important foliar disease of chickpea in many countries. The fungus is heterothallic and requires the pairing of two compatible mating types for the teleomorph to develop. In nature, the teleomorph only develops on chickpea debris that overwinters on the soil surface in the ...

Integrated Disease Management of Ascochyta Blight (Ascochyta rabiei) in Chickpea
2018Ülkemizde nohut ekim alanlarında önemli kayıplara yol açan nohut antraknozu [Ascochyta rabiei (Pass.) Labr.]hastalığı, koşulların uygun gittiği mevsimlerde % 100'e varan ürün kayıplarına nedenolmaktadır. Ülkemizde bu hastalığa karşı bazı fungisitler sadece tohumilaçlaması olarak önerilmekte olup, üreticiler tohum ilaçlamasına çok önemvermemekte ve

Variation in pathogenicity of Ascochyta rabiei on chickpeas
Tropical Pest Management, 1989Abstract Studies of the geographic variability of Ascochyta rabiei were done using chickpea cultivars of differing susceptibility under uniform growth room conditions. The pathogenicity of certain isolates particularly those from the Indian subcontinent and Western Asia was greater than that of most isolates collected in the Western Mediterranean ...

Molecular Markers and QTLs for Ascochyta rabiei resistance in chickpea
International Journal for Agro Veterinary and Medical Sciences, 2011Chickpea is an important grain legume of the semi arid tropics and warm temperate zones, various abiotic and biotic stresses are the major bottlenecks for increasing chickpea productivity. Systematic collection and evaluation of wild species for useful traits has revealed presence of a diverse gene pool for tolerance to the biotic and abiotic stresses.

Foliar fungicides to manage ascochyta blight [Ascochyta rabiei] of chickpea in Canada
Canadian Journal of Plant Pathology, 2003Ascochyta blight, caused by Ascochyta rabiei, is a major constraint to chickpea production in Saskatchewan. Foliar fungicides were evaluated at various rates and timings for managing blight epidemics over 18 station years from 1998 to 2000. Dry weather in 1998 resulted in low disease pressure, and fungicide application had no effect on blight severity ...

Genetic analysis of resistance to Ascochyta rabiei in chickpea
2001Aschochyta blight (caused by Ascochyta rabiei) is the major chickpea disease and production constraint all over the world. The use of resistance genes appears to be the most suitable and reliable way to control the disease. The identification of molecular markers associated to resistance genes might help plant breeders producing new resistant varieties.
