The most important foliar diseases in legumes worldwide are ascochyta blights. Up to now, in the Ascochyta-legume pathosystem most studies focused on the identification of resistance genes in the host, while very little is known about the pathogenicity factors of the fungal pathogen. Moreover, available data were often obtained from fungi growing under artificial conditions. Therefore, in this ...

ABSTRACT Historically, the response of chickpea (Cicer arietinum L.) to Didymella rabiei (causal agent of Ascochyta blight) has been mainly related to as complete resistance and it was commonly assayed with qualitative (nonparametric) scales. Two reciprocal populations, derived from intra-specific crosses between a moderately resistant late flowering Israeli cultivar and a highly susceptible ea...

abstract ascochyta blight caused by didymella rabiei is one of the most important diseases of chickpea in ilam and kermanshah provinces, iran. in order to determine the pathogenicity variation of didymella rabiei populations, infected plants in field crops of different regions of both provinces were sampled. one hundred isolates were isolated by chickpea seed meal dextrose agar media. these iso...

Fusarium wilt (FW), caused by Fusarium oxysporum f. sp. ciceris and Ascochyta blight (AB), caused by Ascochyta rabiei are two major constraints to chickpea production. Therefore, two parallel marker-assisted backcrossing (MABC) programmes by targeting foc 1 locus and two QTL regions, ABQTL-I and ABQTL-II were undertaken to introgress resistance to FW and AB, respectively in C 214, an elite cult...

The antimycotic potential of Datura metel (syn. Datura alba Nees.) was investigated in vitro against Ascochyta rabiei, the cause of chickpea blight disease. The pathogen was exposed to various n-hexane concentrations (1, 2, 3 and 4% w/v) of shoot and root extracts of D. metel using poisoning food technique. All the employed concentrations of both root and shoot extracts significantly suppressed...

Chickpea (Cicer arietinum L.) is one of the most popular vegetables in many regions of the world. Pulses are important sources of protein for vegetarian population. Chickpea (Cicer arietinum L.) commonly known as gram is an important pulse crop. In Tunisia, the cultivated area and production have significant instability and decrease, the chickpea crop was affected by biotic and abiotic constrai...

Evolutionary relationships were inferred among a worldwide sample of Ascochyta fungi from wild and cultivated legume hosts based on phylogenetic analyses of DNA sequences from the ribosomal internal transcribed spacer regions (ITS), as well as portions of three protein-coding genes: glyceraldehyde-3-phosphate-dehydrogenase (G3PD), translation elongation factor 1-alpha (EF) and chitin synthase 1...
