Data on pollen dispersal and interspecific crosses between foxtail millet,
an autogamous summer cereal, and the green foxtail, are reported. Progeny o
f hybrids are identified as the giant green foxtail, a botanical variety of
green foxtail called "major". Growth and reproduction of the two wild type
s are compared as well as their competition effect against maize. The fitne
ss associated with a herbicide resistance gene transferred to millet is stu
died. The results are used to make inferences about the impact of gene flow
from the crop to its wild relative.
