However, it is also known that sometimes the correlation
between breeding system and genetic diversity
may not be very strong (Clegg et al., 1992). This
apparent contradiction is attributable to various other
parameters (some of which are yet not very clear)
have to be considered. This also confirms that there
is still a need to survey the current information on the
breeding systems of the wild relatives of crop species,
which should be complemented by research where
information is lacking or needs refining.
