AbstractTerminal deficiencies (TDs) generated by the r-XI deletion system in maize were used to physically map RFLP markers on the short arm of chromosome 2 (2S) and the long arm of chromosome 6 (6L), chromosome 8 (8L), and chromosome 10 (10L). Five TDs on 2S, 8 on 6L, 10 on 8L, and 20 on 10L were isolated using the recessive morphological markers lg1, py1, j1(gl18), and sr 2, respectively, for selection. Two exceptional TDs on 2S and 8L also have a second breakpoint on the long arm of chromosome 2 (2L) and 8L, respectively. The physical mapping of RFLP probes in relation to TD breakpoints was done by Southern hybridization. The five TDs on 2S divide chromosome 2 into four regions, all of which are distinguishable by RFLP markers. Likewise, three remaining chromosome arms are divided by TDs into RFLP-marked regions: 8 TDs divide 6L into five regions, 10 TDs divided 8L into seven regions, and 20 TDs divide 10L into three regions. The linear order of the physical map of 6L and XL is consistent with that of the genetic maps, but that of 2L and 10L is not. Four groups of markers on 2S as well as 2L, and two on 10L are in reverse order in the physical map compared with the genetic maps. Other intriguing results are that breakpoints of TDs on 6L and 8L are distributed throughout the selected region, but most of those on 2L and 10L cluster in a region near the centromere; a single TD arose after fertilization.
