Description Wild relatives of crops, sorghum being no exception, continue to
play a key role in the development of high performing cultivars.
Among the 22 species comprising this highly variable genus, only
one, Sorghum bicolor, is commercially cultivated for food, feed and
bioenergy production. The wild sorghums thus offer opportunities
for further genetic enhancement of this crop. Profi table utilization of
wild species however demands an inter-disciplinary, multi-pronged
approach to increase the probability of achieving the desired genetic
improvement. To this end, this chapter presents a review of the current
knowledge on (1) biosystematic aspects such as botany, taxonomy
and classifi cation, (2) domestication and evolution, including centers
of diversity, genetic diversity, chromosome homologies and species/
phylogenetic relationships, (3) genetic resources, genepools and
conservation perspectives including collections and preservation of
germplasm, (4) utilization aspects including the specifi c potential of
the wild species in crop improvement with reference to insect and
disease resistance, yield, grain quality, ecological adaptation, allopatric
resistance, and (5) strategies to maximize utilization of wild germplasm
resources including direct hybridization, reproductive barriers and their
circumvention, chromosome and physiological manipulation, the gaps
between hybridization and utilization and molecular interventions.
Recent advancements in biotechnology, in particular, are expected
to increase the effi ciency and range of use of these wild sorghum
species.
