Reduced maps very close to NPI238 on chromosome 1L

--Paul H. Sisco

To localize reduced on the maize RFLP map, 42 F2 plants having the reduced phenotype were analyzed. (The genotype of the original cross was rd-A6325 x 4Co63). There was no recombination between reduced and NPI238 among the 42 plants, showing that reduced is very closely linked to that marker in the distal region of chromosome 1L. Recombination data indicated that BNL8.29A was the next most distal and BNL7.25 the next most proximal RFLP marker of the probes tested.
