INFECTION OF LENTIL PLANTS WITH FUNGAL DISEASESAND THEIR IMMUNOLOGICAL ASSESSMENT UNDER CONDITIONS OF ABSHERON

The article deals with fungal disease infection and assessment of lentil cultivars under Absheron conditions. Based on phytopathological and immunological assessment of cultivated lentil accessions and their infection with fungal diseases, plants showing resistant and tolerant response to diseases were selected and recommended to be used in breeding work. In the research work, infection of new lentil cultivars introduced from IСARDA with fungal disease and their phytopathological evaluation were carried out. 12 samples of lentil varieties were taken, observations were made during flowering and ripening in different vegetation phases, and their infection with fungal diseases was recorded. Fusarium, ascochytosis and yellowing (nutritional deficiency) were recorded in the 12 varieties of the studied lentils (Lens culinaris L). The evaluation of the diseases detected in these accessions was carried out according to the scale used in the phytopathological evaluation of leguminous plants. The immunological and phytopathological assessment of fungal diseases on lentil forms revealedthat cultivated accessions p. Jasmin, 6206/8461/3-5, 75/7700/6-8, ILL6002 were infected with fusarium wilt, the accession 6037/1073/3-5 with ascochytosis. According to the disease severity scale out of 4 samples infected with fusarium disease, two were resistant and rated 1, 2 samples were infected with weakly resistant ascochytosis with rating 2, and one form was evaluated as resistant sample with rating 1. In two lentil samples, yellowing (nutritional deficiency) disease was recorded as persistent with a score of 1. During the phytopathological assessment of lentil variety samples against fungal diseases, p. Arzu, p. Milana, 6037/1073/3-5, 6002/99/009/5-5, 358/10870/24-3, 6994/DPL62/2-7 were highly resistant and immune as no disease was observed. Since no disease was observed in 6 out of 12 varieties of lentils included in the collection, it is recommended to use them as resistant forms and include in breeding programs.
