In
Northeastern Brazil, eggplant production is drastically reduced, especially
when the high temperatures during flowering and fruiting of the eggplant for a
prolonged period, makes pollen grains unfeasible, prevents full fertilization,
results in defective fruits, reduces the fruit fixation rate, number of fruits
and yield per plant. In this regard, the assessment of pollen viability under
such conditions becomes of fundamental importance and can be used as an
auxiliary trait in the selection processes of tolerant genotypes. This book
chapter addresses the aspects to be considered when choosing and implementing
the pollen viability assessment methodologies currently described for use on
eggplants grown under high temperatures and their associations with the traits
known to influence: fruit fixation rate, number of fruits and production per
plant. There is no universal methodology for use in eggplant; but, under high
temperatures the use of Carmine Acetic, Alexander stain and the germination of
pollen grains in vitro proved to be efficient and with a high and positive
genetic correlation with the traits associated with tolerance; they are easy to
perform and inexpensive for pollens extracted from flowers in the field or
greenhouse
