Fusarium wilt (FW) significantly affects the growth and development of chickpea (Cicer arietinum L.), leading to substantial economic losses. FW resistance is a quantitative trait that controlled by multiple genomic regions. In this study, meta-analysis was conducted on 32 loci (QTLs) associated with resistance, identification seven meta-QTL (MQTL) regions distributed across CaLG2, CaLG4, CaLG5, CaLG6 linkage groups. The integrated analysis revealed several candidate genes potentially important for including sensing (e.g., LRR-RLK), signaling mitogen-activated protein kinase [MAPK1]), transcription regulation NAC, WRKY, bZIP). Subsequently, marker-assisted backcrossing (MABC) trial executed leveraging MQTL outcomes introgress from an FW-resistant cultivar (Ana) into superior high-yielding Kabuli (Hashem). breeding process extended over 5 years (2018-2023) resulted in BC3F2 genotypes. Consequently, 12 genotypes carrying homozygous alleles were chosen, three showing genetic backgrounds matching 90%-96% recurrent parent. findings study have significant implications upcoming programs, encompassing fine-mapping, breeding, engineering, consequently contributing effective control improved production chickpea.
