Abstract

The crop production of maize is now significantly impacted by biotic stresses. Among these biotic constraints, the Turcicum leaf blight disease caused by Exserohilum turcicum is a key obstacle to reducing the yield globally. Therefore, to overcome this issue, identifying the TLB-resistant genotypes is a necessary effort. Microsatellite markers in the current study revealed a substantial degree of divergence. The PIC values and allelic diversity showed that the markers used to examine the polymorphism level present in the examined inbred lines were highly effective. During this study, 212 alleles in total ranging from 2 to 5, with an average of 2.83 alleles per locus, were found at 75 marker loci. Further more, the maize inbreds were divided into two distinct clusters, identified cluster-I and cluster-II, by the UPGMA dendrogram. Except for V-25 from cluster II, almost all of the inbred lines exhibited significant resistance to TLB disease. These TLB-resistant sources can be used in future plant breeding programs.
