The investigation was focused on transfer of the fusarium wilt resistance into elite cultivar. Screening of chickpea parents (ICC 506 EB and Vijay), 196 RIL’s (Obtained from ICRISAT, Hyderabad), F2and BC1F1 populations for fusarium wilt resistance were done by Pot culture method and wilt sick plot method. The BC1F1 segregated in 1:1 ratio for resistance and susceptibility and F2 progenies segregated in a ratio of 1 resistant and 3 susceptible. The RILs closely fit a 1:1 segregation ratio for resistance and susceptibility indicating that resistance to fusarium wilt was monogenic with the recessive allele conferring resistance to fusarium wilt in this population. The parents were screened with 43 SSR primers. 22 markers were identified polymorphic. The polymorphism ranged from 57.14 to 100.00 per cent. The PIC scores of SSR markers ranged between 0.0371 and 0.9226. The BC1F1 population screened with three polymorphic foreground markers (TR19, TA110 and GA16) and four polymorphic background markers (TS82, TA194, TA135 and TA 22). The reported markers linked to susceptibility and resistance proved their effectiveness and further can be exploited for maker assisted selection (MAS) of fusarium wilt resistance breeding in chickpea.
