Pathogenic variation of Didymella rabiei isolates causing Chickpea blight in three western provinces of Iran
Mirzapour S, Darvishnia M, Bazgir E, Mirzaei Najafgholi H (2020) Pathogenic variation of Didymella rabiei isolates causing Chickpea blight in three western provinces of Iran. Plant Pathology Science 9(2):1-13. DOI: 10.2982/PPS.9.2.1 Introduction: Chickpea blight, caused by Didymella rabiei, is the most limiting factor in chickpea production areas in the world, including the western province...
متن کاملAFLP analysis of a worldwide collection of Didymella bryoniae.
Didymella bryoniae (anamorph Phoma cucurbitacearum) is an ascomycete that causes gummy stem blight, a foliar disease that occurs on cucurbits in greenhouses and fields throughout the world. In a previous study using RAPD analysis, little genetic diversity was found among isolates of D. bryoniae from New York and South Carolina, USA. Here we report the use of amplified fragment length polymorphi...
متن کاملThe Detection and Characterization of QoI-Resistant Didymella rabiei Causing Ascochyta Blight of Chickpea in Montana
Ascochyta blight (AB) of pulse crops (chickpea, field pea, and lentils) causes yield loss in Montana, where 1.2 million acres was planted to pulses in 2016. Pyraclostrobin and azoxystrobin, quinone outside inhibitor (QoI) fungicides, have been the choice of farmers for the management of AB in pulses. However, a G143A mutation in the cytochrome b gene has been reported to confer resistance to Qo...
متن کاملGeneration Means Analysis of Leaf and Stem Resistance to Gummy Stem Blight in Cucumber
Leaf and stem resistance to gummy stem blight [Didymella bryoniae (Auersw.) Rehm.] in five resistant by susceptible crosses of cucumber (Cucumis sativus L.) was investigated using generation means analysis. No single gene of major effect controls either leaf or stem resistance to gummy stem blight in these five crosses. The mean number of effective factors controlling leaf resistance in the cro...
متن کاملIdentification and Characterization of the Causal Organism of Gummy Stem Blight in the Muskmelon (Cucumis melo L.)
Gummy stem blight is a major foliar disease of muskmelon (Cucumis melo L.). In this study, morphological characteristics and rDNA internal transcribed spacer (ITS) sequences were analyzed to identify the causal organism of this disease. Morphological examination of the Jeonbuk isolate revealed that the percentage of monoseptal conidia ranged from 0% to 10%, and the average length × width of the...
