“…Understanding A. rabiei gene/genotype flow is especially relevant in a country such as Syria that lies in the center of the origin of chickpeas. Comparing the population structure of the pathogens isolated from wild and cultivated chickpeas using DNA markers allow the estimation of gene flow among populations from different hosts and geographic regions [46].…”

Ascochyta blight (AB) caused by Ascochyta rabiei (Pass.) Labr. is an important and widespread disease of chickpea (Cicer arietinum L.) worldwide. The disease is particularly severe under cool and humid weather conditions. Breeding for host resistance is an efficient means to combat this disease. In this paper, attempts have been made to summarize the progress made in identifying resistance sources, genetics and breeding for resistance, and genetic variation among the pathogen population. The search for resistance to AB in chickpea germplasm, breeding lines and land races using various screening methods has been updated. Importance of the genotypeˆenvironment (GE) interaction in elucidating the aggressiveness among isolates from different locations and the identification of pathotypes and stable sources of resistance have also been discussed. Current and modern breeding programs for AB resistance based on crossing resistant/multiple resistant and high-yielding cultivars, stability of the breeding lines through multi-location testing and molecular marker-assisted selection method have been discussed. Gene pyramiding and the use of resistant genes present in wild relatives can be useful methods in the future. Identification of additional sources of resistance genes, good characterization of the host-pathogen system, and identification of molecular markers linked to resistance genes are suggested as the key areas for future study.

“…Environmental stress is a primary cause of crop loss worldwide, resulting in average yield losses of more than 50% for major crops every year (Chaves and oliveira, 2004). Drought stress is the second important constraint of yield in crops after disease (Singh et al, 1994). Drought stress causes deceleration of cell enlargement and thus reduces stem length by inhibiting inter nodal elongation and also checks the tillering capacity of plants (Ashraf and O'Leary, 1996).…”

Article InformationA field experiment was laid out in order to evaluation of effects water stress on yield and yield components of wheat cultivars in Lorestan province in Islamic Azad University, Boroujerd branch, Iran at 2014. The experiment was laid out in a split-plot design based on randomized block design with three replications. Treatments were irrigation in five levels such as 1: four period irrigation after anthesis, 2: three period irrigation after anthesis, 3: two period irrigation after anthesis, 4: one period irrigation after anthesis and 5: control in main plots and three wheat cultivars (Shiraz, Pishtaz and Bahar) in sub plots. The results showed that, the effect of water stress, cultivar and interaction between them on all parameters were significant at 1% level. The height of Pishtaz cultivar was taller than other cultivars. The Pishtaz cultivar with one period irrigation after anthesis had the highest number of spike per square and Bahar cultivar with one period irrigation after anthesis had the lowest number of spike per square. However, 1000-grainwas decreased in water deficit treatment. However, the Pishtaz cultivar with four period irrigation had the highest plant dry weight and grain yield and Bahar cultivar non irrigation treatment after anthesis had the lowest plant dry weight and Shiraz cultivar in nonirrigation treatment had the lowest grain yield. The results showed that yield and yield components of common wheat decreased with increasing of water deficit and for increasing in grain yield of wheat complete irrigation are needed. However, Pishtaz cultivar had a highest grain yield and dry matter production. Then we can increase grain yield and production of wheat with cultivation of Pishtaz cultivar and avoid of water stress.

“…More than 50 pathogens including viruses and 54 insect pests have been reported on chickpeas from different parts of the world (Nene 1980;van Rheenen 1991;Singh et al 1994;Kumar et al 2008). Viral diseases often cause significant yield losses (Bos et al 1988;Kumar et al, 2008).…”
