DNA markers for downy mildew resistance genes in sorghum.
The random amplified polymorphic DNA technique was used to find markers for a downy mildew resistance gene in sorghum. Of the 674 random primers screened for polymorphism, 2 amplified fragments were linked to a downy mildew resistance gene in sorghum line SC414. Utilization of an existing restriction fragment length polymorphism mapping population (IS3620C x BTx623) also revealed two markers that are linked to a different resistance gene in another sorghum line, BTx623.
