  1. Molecular markers used in these studies were Single nucleotide polymorphism (SNPs), Simple sequence repeats (SSR), restricted fragment length polymorphism (RFLP), cleaved amplified polymorphic sites (CAPS). Phenotypic traits like area under disease progress curve (AUDPC), plant disease index (PDI), disease leaf area (DLA), incubation period (IP), disease severity (DS), weighted mean disease (WMD) were used for QTL analysis.
