The inheritance of resistance to castor wilt derived from ‘Haritha’and ‘48-1’conferring resistance to race 1 of the pathogen Fusarium oxysporum F. sp. ricini has been determined. The F2 individuals and backcross F1 families of two crosses Haritha and ‘48-1’(resistant)בKranthi’(susceptible) were screened against Fusarium wilt in combined tests which indicated dominant control by single locus of tightly linked gene (s). Bulked segregant analysis (BSA) was carried out on F2 and BC1F1 individuals with 186 RAPD primers that resulted in the identification of two RAPD markers linked to resistance that distinguished the bulks. Of these, the RAPD markers OPH-124973 and OPJ-154268 were tightly linked to ‘Haritha’and ‘48-1’at a distance of 5.0 cM and 7.0 cM to wilt resistance. These closely linked markers to the wilt resistance gene (s) provide a valuable basis for marker-assisted selection in castor breeding programs. Not Available |
