Identification of RFLP markers linked to a gene for downy mildew resistance (Sdm) in sorghum Academic Article

abstract

• The Sdm locus in sorghum accession SC325 confers resistance to downy mildew caused by pathotypes 1 and 3 of Peronosclerospora sorghi. Restriction fragment length polymorphism linkage analysis placed the Sdm locus near loci detected by probes pSbTXS552 and pSbTXS361 at 5.0 and 7.9cM, respectively. Fragment patterns for the cross segregating for disease resistance differed from those for the original mapping cross, preventing assignment of Sdm to a linkage group. Keywords: Peronosclerospora sorghi, resistance, RFLP, linkage, hybrid breeding.
