Comparative analysis and study of powdery mildew on samples of cultivated barley (Hordeum vulgare L.)

In this study, a comparative analysis of the degree of powdery mildew infection was conducted on 70 samples of cultivated barley (Hordeum vulgare L.) sown in 2023 in the experimental fields of the Institute of Genetic Resources. As a result of phenological observations, samples demonstrating high resistance to the disease were identified. The selected samples, based on their resistance indicators, are recommended as initial material for the development of high-yielding and disease-resistant varieties in the future.
