Technical Abstract: While sorghum is recognized as an inherently drought tolerant species, breeders have made great strides in enhancing this trait using traditional methods. The recognition of two distinct types of drought tolerance and the introgression of exotic germplasm via the Sorghum Conversion Program have led to widespread acceptance of the importance of the ‘staygreen’ trait. With the sequencing of the sorghum genome, breeders and molecular geneticists stand poised to decipher some of the basic mechanisms underlying drought tolerance in sorghum, and these discoveries may have far-reaching applications across a range of species. New techniques in molecular mapping and gene discovery will likewise lead to a greater level of understanding of these complex mechanisms, and will greatly enhance our ability to utilize this new information.
