response of chickpea lines to ascochyta rabiei at two growing stages
نویسندگان
چکیده
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 tolerance at seedling stage proved response to the pathogen under field condition. disease at seedling and adult plant stage exhibited high association, although level of infection was higher at adult plant stage. in glasshouse 65 genotypes at seedling stage and in field experiment 14 genotypes at pod formation stage were resistant to the pathogen. following green house and field screening methods, six genotypes flip98-229c, flip82-150c,ncs 950204, ncs 950219, ncs 9903 and paidarxparbat from narc and six lines (flip 00-20c, flip 02-18c, flip 02-44c, flip 97-120c, flip 02-39c and flip 97-102c) from icarda found resistant for multilocational / agronomic evaluation and use as resistant parent trials for high yielding ab resistance breeding varieties.

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 کاملAnti-oxidative enzyme changes associated with chickpea calli tolerant to Ascochyta rabiei culture filtrate.
Ascochyta blight caused by Ascochyta rabiei (Pass.) Labrousse is a major biotic constraint in production of chickpea. In the present investigation, all chickpea genotypes [E100Y (m), Gaurav, Pb-7 and L550] induced 100% callus on standard medium with greenish colour and fragile structure. These calli were used for in vitro screening against pathogen, A. rabiei culture filtrate at 0, 5, 10, 15 an...
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 کاملrabiei, the causal agent of Ascochyta blight of chickpea (Cicer arietinum L.), and toxin production-by the wild type
Ascochyta rabiei is the causal agent of blight of chickpea, an important food legume crop for human populations in Developing Countries. All reliably identified isolates of the fungus produce toxins in culture, known as the solanapyrones, of which solanapyrone A is the most frequently found and also the most toxic. The principal aim of the project was to determine the role of this toxin in the ...
