plants became infected early in the season, the susceptible
plants could be completely killed, but the
resistant plants survive and produce a grain yield.
There is no infection by rust, and the mechanism of
smut resistance has not been studied.
In a discussion of male sterility, it was stated that
the criterion for pollen viability after storage is its
ability to pollinate cytoplasmic male-sterile plants
and produce hybrids. Reversion of male sterility can
occur due to mutation of cytoplasmic genes. Also,
there is variation in a particular cytoplasm, and
cytoplasmic male sterility may be more complex
than is usually understood.
