Mehrabioun Mohammadi M, Ahmadi N, Arzanlou M (2020) Dutch elm disease. Plant Pathology Science 9(1):91-100.         DOI: 10.2982/PPS.9.1.91.

Elm trees are one of the most important ornamental trees and are widely used in the design of urban green spaces. Dutch elm disease is recognized as one of the most important elm diseases in the world. The disease has become an epidemic worldwide and at least three species of Ophiostoma including O. ulmi, O. novo-ulmi and O. Himal-ulmi that differ in geographical distribution and invasion power, are involved in this disease. In Iran, O. ulmi and O. novo-ulmi are known to involve in this disease, with O. novo-ulmi being more virulent. Management of the disease is mainly achieved through preventive and quarantine methods, health measures, resistant cultivars and the use of chemical compounds. Various aspects of the disease, including disease symptoms and signs, pathogen biology and ecology, disease management methods are reviewed in this paper.

Soleymani SH, Tahmasebi Z, Asherf Mehrabi A, Kanouni M (2021). Agronomic traits of twenty-one resistant, semi-resistant and susceptible chickpea genotypes to blight disease. Plant Pathology Science 10(2): 82-92.  Doi: 10.2982/PPS.10.2.82.
Introduction: Blight caused by Ascochyta rabiei is the most destructive disease of chickpea worldwide. Identification of agronomic and morphological properties of disease-resistant cultivars is necessary to set up a suitable chickpea breeding program. Materials and Methods: Twelve agronomic and morphological properties of 21 resistant, semi-resistant, and susceptible chickpea genotypes were investigated in a field experiment in a randomized complete block design with six replications in one agronomic year in western Iran. Results: All genotypes were divided into three main clusters based on the UPGMA dendrogram. The lowest yielding genotypes were located in cluster II and IDDMAR-2012-32 genotype was susceptible to disease and desi-type in this cluster. The genotypes with the highest yield were placed in cluster III, and the genotype Gebres 419-2 was resistant to the disease and the desi-type in this cluster. Among the Kabuli-type genotypes, ILC482 was included in cluster III as a high-yielding and semi-disease-resistant cultivar, and low-yielding FLIp-02-65C and FLIp-01-164C lines along with disease resistance were included in cluster I. Conclusion: Gebres 419-2 can be crossed with FLIp-02-65C or FLIp-01-164C to produce robust, high-yielding Kabuli chickpea varieties with large seeds.
