Gharacheh N. & Sadravi  M. 2015. Five important fungal diseases of  pulse crops in Iran. Plant Pathology Science 4(2):17-25. 

Bean, pea, lentil, vetch and broad bean grains are rich in protein.  Kohgiluyeh and Boyer-Ahmad (a province in the southwest Iran) is one of the cultivation area of the pulses. In this province, five important fungal diseases included Fusarium wilt, Fusarium root rot, Ascochyta blight, Alternaria blight, and charcoal rot, are common on these plants. Symptoms of these diseases, key morphological characteristics of the pathogens and their distribution areas in Iran and the world is described.

Vafaei S H (2019) Blight disease of chickpea. Plant Pathology Science 8(2):45-57. DOI: 10.2982/PPS.8.2.45
Blight disease caused by Mycosphaerella rabiei is the major constraint for chickpea production worldwide. Pathogenicity of pathogen and the analysis of its genetic diversity in pathogen population are necessary for management of the disease. Different strategies such as seed treatment, application of resistant cultivars, adjustment sowing date and integration of resistant genotype with post-infection application of fungicides have been recommended to reduce the losses caused by the disease. The use of resistant cultivars is the best management strategy to minimize yield losses due to blight. But because of the considerable variation in pathogenicity of the fungal population and partial resistance in germplasm of chickpea the effectiveness of resistant cultivars is limited. Different aspects of the biology, pathogenic and genetic diversity, resistance inheritance and the management options are discussed in this paper.

Mirzapour S, Darvishnia M, Bazgir E, Mirzaei Najafgholi H (2020) Pathogenic variation of Didymella rabiei isolates causing Chickpea blight in three western provinces of Iran. Plant Pathology Science 9(2):1-13. DOI: 10.2982/PPS.9.2.1
 
Introduction: Chickpea blight, caused by Didymella rabiei, is the most limiting factor in chickpea production areas in the world, including the western provinces of Iran. The aim of this study was to investigate the pathogenic diversity of the isolates collected from western provinces of Iran (Ilam, Lorestan and Kermanshah) on differential lines of chickpea, as well as the relationship between pathogenic diversity of the isolates and their geographical origins. Materials and Methods: During the 2017-18 chickpea growing season, samples of infected plants were collected from fields in western provinces and transferred to the laboratory. Then 100 pure isolates of D. rabiei were obtained. Based on the location of collection, the isolates were divided into 20 groups. Based on the morphological characteristics, one isolate from each group was selected as a representative for greenhouse experiments. The pathogenic diversity of theses 20 isolates was assessed on eight differential lines of chickpea. The factorial experiments were performed in a completely randomized block design under greenhouse conditions. Results: The results of analysis of variance showed that there was a significant difference between differential lines and isolates at a probability level of p<0.01. Based on the response of the differential lines, the pathogenic isolates were grouped into three pathogenic groups, including pathogenic group 1 (weakly aggressive), group 2 (aggressive or moderately aggressive), and group 3 (highly aggressive). The isolates from Kermanshah and Lorestan Province were classified into Group 1 and the Ilam isolates into Groups 1, 2 and 3. The greatest severity of the disease was found in three isolates of Ilam province. The variety ILC3996 showed the highest resistance to all isolates. Conclusion: D. rabiei isolates from three western provinces of Iran are divided into three pathogenic groups: 1 (low aggressive), 2 (moderately aggressive), and 3 (highly aggressive). Highly aggressive isolates identified in Ilam province can be used in chickpea breeding programs to produce resistant cultivars to the disease.. The wild variety ILC3996 has resistant genes against these pathogenic groups and showed resistance to all of these isolates.

Azizi K (2022) Host preference and population level of Pratylenchoides ritteri on six legume crops.
Plant Pathology Science 11(1):36-47.         Doi: 10.2982/PPS.11.1.36.


Introduction: Legumes are the most important source of human food after cereals. More than 70 species of plant-parasitic nematodes have been reported from legumes of the world. Some of these nematodes cause great damage to these plants. Pratylenchoides ritteri is widespread in Iran on various plants such as legumes. Material and Methods: The number of P. ritteri nematodes per kg of soil in an infected field soil was counted and this soil was used for a greenhouse experiment. Nematode reproductive factor and some plant growth traits in six plants including; Broad bean, soybean, lentil, bean, mung bean, and Chickpea were studied under greenhouse and field conditions. Tests were performed in randomized complete block designs and the data were analyzed using SPSS 22 software. Results: All the plants were hosts for the nematode and the reproductive factor of the nematode was higher than one. The highest reproductive factor was found in soybean and the lowest in mung bean. Under greenhouse conditions, a decrease in most plant growth indices was observed in all infected plants. Among these plants, beans showed the largest decrease and mung bean the smallest decrease in growth indices. Conclusion: Broad bean, soybean, lentil, bean, mung bean, and chickpea are hosts for P. ritteri and this nematode can cause decreases in most plant growth indices.
