Description Gene flow between cultivated and their
wild relatives is one of the main ecological concerns
associated with the introduction genetically modified
(GM) cultivars. GM sorghum cultivar has been
developed and its commercial production may be
possible in the near future. The rate of gene flow
depends on the fitness of wild 9 cultivated sorghum
hybrids. The study aimed at estimating adaptive
values of wild 9 cultivated sorghum hybrids in
generations F1, F2, and F3 compared to their parents.
Artificial crosses of four wild sorghums, five cultivated
sorghums, and two male sterile lines were made
to produce the F1 generation, which were advanced to
F2 and F3. Each hybrid generation and their respective
parents were evaluated for their adaptive value at two sites in a randomised complete block design with
seven replicates. The resulting progenies did not
show serious fitness penalties. Some hybrids were as
fit as their respective wild parents and no consistent
differences exist between the three generations studied.
Thus, the resultant wild 9 cultivated hybrids
may act as avenue for introgression.
