Abstract

Association of resistance of chickens to Marek's disease (MD) with the allele B21 of the B blood-group system was first reported by Hansen et^ al. (1967). The 15 system was later shown to identify the major histocompatibility complex (MHC) of the chicken (Schierman and Nordskog, 1961), and the association of resistance to MD with the B^1 haplotype was confirmed (Longenecker et al., 1976; Briles et al., 1977). The objective of this study was to determine if differences in resistance to MD were associated with two, previously unknown _B haplotypes detected in two inbred lines of White Leghorns that differed widely in their resistance to MD.
