A total of 347 polymorphic markers were scored in the genotype analysis of 156 progeny in the BA F2population,with each primer pair yielding polymorphic bands at a single locus.After exclusion of 47 unlinked markers,300 marker loci were grouped into 20 LGs,which matched the 20 consensus LGs.Finally,a genetic map(Fig.1),designated as the BA map,was constructed with 20 LGs covering a total genetic distance of2347.30 c M with an average density of one marker for every7.82 c M(Table 2).The number of mapped markers per LG ranged from 10(H and D2)to 23(A2)with an average of 15markers.The largest and smallest genetic distances between adjacent markers were 52.3 c M and 0.1 c M,respectively.Because of low marker density(Fig.2)and infrequent recombination compared with distal regions,our map did not cover all centromeric blocks,resulting in coverage of only a portion of some chromosomes(N,C2,M,O,H,and F)or of two clusters of markers,one from each arm(K and B1)in the F2mapping study.Six marker orders(N,A1,M,B2,and E)in our genetic map that were in conflict with the physical map could be due to sequence assembly errors,inversions,and segregation distortion.
