Karbalaei Khiavi H, Pirayesh A, Seyed Masoumi SY, Khabbaz Jolfaei H (2021). Reaction of ten peach and ten nectarine cultivars to powdery mildew. Plant Pathology Science 10(1):1-13.      Doi: 10.2982/PPS.10.1.1.
Introduction: Powdery mildew caused by Podosphaera pannosa is one of the most important diseases of peaches and nectarines worldwide, including Iran. The aim of this research was to investigate the response of peaches and nectarines under cultivation in Iran to the disease. Materials and Methods: Reaction of ten peach cultivars vs. Robin, Early Red, Red Top, Shasta, Amesdn, Velvet, Anjiri, Paeizeh, Dixi Red, and Sun Crest, and ten nectarine cultivars vs. Independence, Stargold, Sangold, Sanking, Giuta, Shabrang Karaj, Vega, Orion, Jiova and Veinberger were evaluated for disease in natural and artificial infection conditions in two experiments in a randomized complete block design with three replications over two years at the Meshgin Shahr Agricultural and Natural Resources Research Station. Results: Analysis of variance of experimental data showed that there was a significant difference between cultivars of each plant at a probability level of 1%. Peach cultivars Anjiri and Red top were very resistant, Velvet, Shasta and Early red ‎were resistant; Amesdn, Dixi red and Robin were moderately resistant; Sun ‎crest was susceptible and Paeizeh was in very susceptible. Weinberger nectarine cultivars were resistant and Independence, Stargold, Sanking, Giuta, Shabrang Karaj, Vega, Orion and Jiova cultivars were semi-resistant and Sangold was very susceptible to disease.  Conclusion: Eighty percent of the studied peach cultivars are very resistant to semi-resistant and 20% sensitive and very sensitive, 90% of the studied nectarine cultivars are resistant to semi-resistant and 10% susceptible to powdery mildew. Findings of this research should be considered in the management of peach and nectarine powdery mildew.

Sadeghi Garmaroodi H, Seyed Masoumi SY, Nankali A (2022) The reaction of thirteen peach and nectarine cultivars to Verticillium wilt. Plant Pathology Science 11(1):60-73.                  Doi: 10.2982/PPS.11.1.60.
Introduction: Verticillium wilt, caused by Verticillium dahliae, is one of the most important soil-borne diseases of stone-fruit trees. Materials and Methods: Samples showing evidence of Verticillium wilt were collected from stone fruit orchards in the suburbs of Shahroud and Damavand and four isolates of V. dahliae were obtained. The fungal inoculum was prepared on sterile wheat grains and the response of 13 peach and nectarine cultivars propagated by grafting on GF305 (almond-peach hybrid) rootstock was inoculated with it in the canopy area in the garden in early spring. Sixteen weeks after inoculation, disease severity was recorded on a three-point scale. Results: All peach and nectarine cultivars were classified as very susceptible, susceptible, or semi-susceptible and none of them showed resistance. The Nectarine Independence cultivar was highly susceptible to disease, while the peach cultivar had the lowest disease severity index and was therefore classified as semi-susceptible. Conclusion: Among these cultivars, the Romestar peach cultivar is less susceptible to the disease.
