Cytoplasmic Male Sterility
The phenomenon of male sterility (MS)
is described as inability of a plant to produce fertile pollen. For hybrid
breeding this is a very usefull instrument, because the plant is prevented
from selfing by pollen sterility. In this way it is possible to produce
pure hybrid seeds under usage of the heterosis effect.
In most cases The reason for cytoplasmic
male sterility lies in mitochondrial genome rearrangements.
