“…Our finding is in agreement with earlier reports for a difference in aggressiveness of A. rabiei isolates from Iran ( Shokouhifar et al, 2003 ; Vafaei et al, 2015 ) and India ( Kumar et al, 2005 ). Highly genetic diversity and aggressiveness of A. rabiei isolates collected from “Kermanshah” province can be concluded by highly sexual reproduction and recombination in A. rabiei population or selection pressure imposed by improved cultivars on pathogen that lead to change of A. rabiei local population and breaking down of resistance.…”

“…Highly virulence diversity of A. rabiei with six physiological races in Syria and Lebanon ( Reddy and Kabbabeh, 1985 ), 11 pathotypes in USA ( Jan and Weise, 1991 ) and 14 pathotypes group in Canada ( Chongo et al, 2004 ) has been reported. Different strategies for integrated diseases management in chickpea including crop rotation, adjusting sowing dates, application of fungicides and use of AB-resistance sources have been recommended in chickpea production ( Ben Mohamed et al, 2010 ; Kimurto et al, 2013 ; Vafaei et al, 2015 ). Changes in pathogen population, mutation and variability of pathotypes in A. rabiei lead to breakdown durable resistant in common resistance sources in chickpea breeding programs ( Kanouni et al, 2011 ).…”

“…The variation in aggressiveness detected within sexually recombinant A. rabiei populations worldwide has led to the erosion of resistant host genotypes (McDonald and Linde, 2002; Peever et al, 2012; Mahiout et al, 2015; Vafaei et al, 2015; Tekin et al, 2017). Although not directly comparable due to a number of factorial differences such as host genotype, isolate and bioassay conditions, several in country studies have identified diversity of aggressiveness within A. rabiei populations.…”

Evidence and Consequence of a Highly Adapted Clonal Haplotype within the Australian Ascochyta rabiei Population

The Australian Ascochyta rabiei (Pass.) Labr. (syn. Phoma rabiei) population has low genotypic diversity with only one mating type detected to date, potentially precluding substantial evolution through recombination. However, a large diversity in aggressiveness exists. In an effort to better understand the risk from selective adaptation to currently used resistance sources and chemical control strategies, the population was examined in detail. For this, a total of 598 isolates were quasi-hierarchically sampled between 2013 and 2015 across all major Australian chickpea growing regions and commonly grown host genotypes. Although a large number of haplotypes were identified (66) through short sequence repeat (SSR) genotyping, overall low gene diversity (Hexp = 0.066) and genotypic diversity (D = 0.57) was detected. Almost 70% of the isolates assessed were of a single dominant haplotype (ARH01). Disease screening on a differential host set, including three commonly deployed resistance sources, revealed distinct aggressiveness among the isolates, with 17% of all isolates identified as highly aggressive. Almost 75% of these were of the ARH01 haplotype. A similar pattern was observed at the host level, with 46% of all isolates collected from the commonly grown host genotype Genesis090 (classified as “resistant” during the term of collection) identified as highly aggressive. Of these, 63% belonged to the ARH01 haplotype. In conclusion, the ARH01 haplotype represents a significant risk to the Australian chickpea industry, being not only widely adapted to the diverse agro-geographical environments of the Australian chickpea growing regions, but also containing a disproportionately large number of aggressive isolates, indicating fitness to survive and replicate on the best resistance sources in the Australian germplasm.

“…For this cause, work in agricultural research is considered a sacred responsibility for us to contribute as much as possible to the development of the agricultural area in the future [2]. In most of the scientific research's it has been indicated that Chickpea is the third main essential legume crops in the world after soybean and faba bean [3,4]. Chickpeas contains high tiers of proteins (up to 30 %), and carbohydrates; additionally they supply a few minerals (P, Ca, K, Mg, Zn and Fe) and nutritional vitamins like niacin as nicely as unsaturated fatty acids [5,6].…”

This study was carried out in Bakrajo Technical Institute, affiliates to the Sulaimania Polytechnic University. The investigation was done to find the relationships between genotypes and sowing times of five chickpeas (Cicer arietinum L.) during 2017-2018 seasons. Genotypes and sowing time are two significant variables which have impact on crop performance. However, heat stress throughout reproductive growth it is possible to cause Significant productivity loss. According to the environment conditions in winter season in the northern Iraq; crop meets slight heat and the acceptable moisture during reproductive growth and maturity. This leads to resulting in maximum and consistent yields, as well as there is a positive correlation between Maturity and Seed Yield (kg/h) as resulted from the experiment. Experimentation was laid out in a randomized complete blocks design (RCBD) with three replications applied. Results of analysis of variance outlined that there was significant difference between chickpeas varieties in the most of traits such as no. of branches per plant, 50 % flowering, no. of pods per plant ,leaf area , seeds weight per plant and the 100 seeds weight plus harvest index, which in turn give a share in to raise yields and yield components. Sowing time and varieties had significant effects on all measured trait, Ghab 1; Filip 2 and Filip 3 winters sowing genotypes gave higher seed yield, 1582.66, 1554.66 and 1533.33 Kg/h respectively. Minimum yield 662, 480 Kg/h was recorded in the Local and Swrka spring sowing genotype.
