Abstract
Dragon’s head (Lallemantia iberica) as an oilseed crop has been recently introduced to Iranian farmers and due to its tolerance to abiotic stresses grown in drylands and rain-fed areas of the country in rotation with cereals and pulses. In this study, fifty Iranian L. iberica landraces were evaluated for the prevalent diseases under field conditions during 2019–2021 in Gonbad-Kavous, North of Iran. A spot lesion/blight symptom was observed in the field and the subsequent classical and molecular mycological studies identified Alternaria tenuissima and A.atra as the causal agents. Subsequently, a complimentary experiment was conducted to screen genotypes for these disease agents under controlled conditions using the proposed scoring system invented in this study. Results showed a significant negative correlation of Sclerotinia stem rot with yield and plant height, while no relationship was observed between Alternaria spot/blight and agronomic traits. Two and twenty-one genotypes were identified as highly resistant and resistant to Sclerotinia stem rot in the field, respectively; where six of them showed additional resistance to Altarnaria spp. in the glasshouse. The resistant/high-yield genotypes identified through this research can be considered valuable sources to be released as new cultivars or exploited in breeding programs.
期刊介绍：
The European Journal of Plant Pathology is an international journal publishing original articles in English dealing with fundamental and applied aspects of plant pathology; considering disease in agricultural and horticultural crops, forestry, and in natural plant populations. The types of articles published are :Original Research at the molecular, physiological, whole-plant and population levels; Mini-reviews on topics which are timely and of global rather than national or regional significance; Short Communications for important research findings that can be presented in an abbreviated format; and Letters-to-the-Editor, where these raise issues related to articles previously published in the journal. Submissions relating to disease vector biology and integrated crop protection are welcome. However, routine screenings of plant protection products, varietal trials for disease resistance, and biological control agents are not published in the journal unless framed in the context of strategic approaches to disease management.
