Abstract

Chickpea (Cicer arientinum) is an important leguminous crop, which is widely grown especially in the Near East. In wet weather conditions, the susceptibility of chickpeas to fungal diseases such as Ascochyta blight and Fusarium blight increases. Thus, selection of disease-resistant and early-ripening varieties is critically needed. The present study was conducted to investigate genome associations in 171 samples of chickpea plants, grown in two experimental stations in Krasnodar (Kuban experimental station) and Astrakhan (Astrakhan experimental station), examine relationship between genes and 12 phenotypic traits as well as explore the association between genes and 3 hallmarks of resistance to pathogenes: Fusarium blight, Ascochyta blight and Noctuidae. Variants associated with different phenotypic traits were identified using a genome-wide association study (GWAS).
