In conclusion, some combinations are possible and
fertile, enabling the gene transference between species,
whereas the fertility degree of other combinations can differ,
indicating partial or complete male sterility, assessed here
based on the pollen viability. The conclusion was also
drawn that infertility is a postfertilization barrier since the
establishment of hybrid combinations is possible, but
breeders will have to apply strategies as described by Yoon
et al. (2006), to continue the breeding program of Capsicum.
