Abstract
The article presents the results of a three-year study of the stability of Psathyrostachys juncea to leaf spots in the feedstock nursery. The production of stable yields of Psathyrostachys juncea is limited by a number of factors, some of them are lesions by a complex of diseases that significantly reduce feed productivity. It has been revealed that the most common diseases of the leaves and stems of Psathyrostachys juncea are: helminthosporiosis, septoriosis and stem (linear) rust. On the basis of phytoimmunological evaluation of samples in the nursery of the starting material, the numbers K 2, K 4, K 6, K 9, K 10, K1 1, K 12, K 14, K 16, K 20 were identified, showing the highest complex resistance to the group of leaf spots.
