Background: Fusarium wilt is one of the widely distributed biotic stress of chickpea limiting its productivity worldwide. The major problem limiting the resistance breeding is screening of germplasm and breeding lines for disease resistance. To address such problems, identification of molecular marker closely linked to resistance locus is an effective strategy.Methods: The RAPD marker A07C417 closely linked H2 locus of Fusarium wilt resistance locus has been converted into SCAR and the loss of initial polymorphism was recaptured by alignment of consensus sequences from SCAR amplified locus for the identification of common motifs. Further, the linkage association of this marker with Fusarium wilt resistance locus has been reaffirmed using Fusarium wilt response of RILs phenotyped for wilt reaction using wilt sick pots and also wilt sick plots.Result: Identification of single nucleotide polymorphism at the consensus SCAR locus between susceptible and resistant cultivar, enabled development of CAPS marker through suitable restriction enzyme Aci I making it an effective codominant marker system for resistance deployment via marker assisted selection.
