reaction of desi and kaboli chickpea genotypes to race 3 and 6 of ascochyta rabiei
the fungal disease, ascochyta blight, caused by ascochyta rabiei is a major yield limiting factor of chickpea (cicer arietinum l.) in many countries, including iran. identification of resistance sources against races or pathotypes of the fungus causing this disease is required for breeding resistant chickpea cultivars. reaction of six selected genotypes of iranian chickpea collection was evalua...
متن کاملEffects of Temperature Stresses on the Resistance of Chickpea Genotypes and Aggressiveness of Didymella rabiei Isolates
Chickpea (Cicer arietinum L.) is an important food and rotation crop in many parts of the world. Cold (freezing and chilling temperatures) and Ascochyta blight (Didymella rabiei) are the major constraints in chickpea production. The effects of temperature stresses on chickpea susceptibility and pathogen aggressiveness are not well documented in the Cicer-Didymella pathosystem. Two experiments w...
متن کاملResponse of Chickpea Lines to Ascochyta rabiei at Two Growing Stages
During winter 2004 and 2005, two field and glasshouse experiments were conducted to evaluate the response of 471 chickpea genotypes to Ascochyta rabiei, as Ascochyta blight (AB) disease in Chickpea (Cicer aurietimum). Frequent rainfall at flowering and pod formation stages made favorite conditions conducive for the infection and symptoms expression. So, the genotypes with high level of toleranc...
متن کاملMating Type Groups of Ascochyta rabiei (Teleomorph: Didymella rabiei), the Causal Agent of Chickpea Blight in Central Anatolia
The distribution of mating types of Ascochyta rabiei (teleomorph: Didymella rabiei) was studied on isolates collected from chickpea growing areas of Central Anatolia. Mating type assessments of 45 isolates from 6 different provinces were conducted under laboratory conditions. After keeping for 5-6 weeks, the pseudothecial development and ascospore production were observed on chickpea stem piece...
متن کاملتعیین تنوع ژنتیکی قارچ عامل بیماری برق‌زدگی نخود [Ascochyta rabiei (Pass.) Lab.] ایران با استفاده از مارکرهای مولکولی RAPD
The poor information available on variation of Ascochyta blight fungus is the most important factor limiting chickpea breeding programs for resistance to blight disease. In this study, efforts were made to detect genetic variation of the pathogen in Iran. The RAPD marker was employed to evaluate 26 isolates collected from 16 provinces. Twelve random primers were used to analyze genomic DNA of t...
