Phytopathological Study Of Disease Resistance Among Genotypes Of Chickpea Under The Conditions Of Absheron

In the course of the study, new varieties of chickpea plant (Cicer arietinum L.), introduced from the ICARDA were studied on the basis of structural analysis and phytopathological assessment of yield and resistance to fungal diseases. Fifty chickpea accessions showed 20% ascochitosis and 40% fusarium wilt (Fusarium oxysporum f. sp. ciceris), 15% mildew and 10% malnutrition. In each genotype, the height of the plant, the number of beans, the number of grains per plant, the mass of 100 seeds and the characteristics of the total productivity were studied, and high variability was recorded for these indicators. Among the accessions, Flip13-128c and Flip13-122 (92 cm) distinguished themselves by the height, Flip13-52c and Flip13-55c (171 pcs.) by the number of beans per plant, by the weight of 100 seeds - Flip13-79c (49.4 g) and by high yield Flip13-56c (95g). During the phytopathological assessment the accessions Flip13-28c, Flip13-36c, Flip13-56c, Flip13-65c, Flip13-66c, Flip13-72c, Flip13-74c, Flip13-105c, Flip13-128c, Flip13-161 were infected with fusarium (1-2 points) and other accessions Flip13-28c, Flip13-83 and Flip13-86c were infected with ascochitosis (2 point). Through cluster analysis, the accessions were grouped according to disease resistance and productivity. As a result, 3 clusters were obtained. Of which the 23 accessions located in the first cluster, (Flip13-26c, Flip13-32c, Flip13-33c, Flip13-39c, Flip13-43c, Flip13-48c, Flip13-52c, Flip13-54c, Flip13-57c, Flip13-58c, Flip13-59c, Flip13- 64c, Flip13-86c, Flip13-89c, Flip13-98c, Flip13-102c, Flip13-106c, Flip13-108c, Flip13-123c, Flip13- 128c, Flip13-161c, Flip13-122c) were rated as productive and resistant, in the second cluster 21 samples, (Flip13-24c, Flip13-30c, Flip13-31c, Flip13-35c, Flip13-36c, Flip13-50c, Flip13-53c, Flip13-55c, Flip13- 56c, Flip13-65c, Flip13 -66c, Flip13 -67c, Flip13-69c, Flip13-76c, Flip13-83c, Flip13-93c, Flip13-105c, Flip13-120c, Flip13-72c, Flip13-74c, Flip13-28c) were evaluated as high productive and low resistant and 6 accessions located in the third cluster (Flip13-47c, Flip13-79c, Flip13-80c, Flip13-81c, Flip13- 109c) were evaluated as highly resistant and high productive accessions. As a result of phytopathological assessment and structural analysis, the 11 accessions (Flip13-33c, Flip13-35c, Flip13-47c, Flip13-52c, Flip13-54c, Flip13-55c, Flip13-75c, Flip13-79c, Flip13-80c, Flip13-81c, Flip13-109c) were assessed as disease-resistant and high-yielding.
