Inheritance and Molecular Mapping of Fusarium Wilt Resistance Gene in Brinjal(Solanum melongena)

: Brinjal, Fusarium Wilt resistance, F2 cross, locus, marker-assisted selection, Genric marker.Abstract
The inheritance of resistance to fusarium wilt derived from AB-2 XAB-52 conferring resistance to
Fusariumoxysporum has been determined. The F2 individuals of the crossAB-2 (resistance) XAB-52 (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 individuals with a set of 250 DNA markers
that resulted in the identification and mapped the FM1 locus between the two DNA markers bNBS-LRR-45 and
bRGA-25 located ~ 2.2 cM apart from each other. These closely linked markers to the wilt resistance gene(s)
provide a valuable basis for marker-assisted selection in castor breeding programs.
