This paper presents the five-year long research results (2007-2011) of
phenological observations (beginning, full flowering and the end of
flowering), morphometric analysis (fruit weight, length, width and thickness
of fruit, as well as length and width of the hilum), the ripening time and
the average yield of selected genotypes of sweet chestnut (Castanea sativa
Mill.). The results show that in terms of time of flowering chestnut trees
examined in the group are very early flowering. The ripening of studied
chestnut trees shows that the earliest harvest tree was Ostros II, VII and
Kostajnica V (09.11.), and Kostajnica III (14.11.) were the latest. The
average fruit weight of the selected sweet chestnut trees was (6.9 g). The
highest average fruit weight (10.6 g), had the examined Ostros I tree, and
the lowest (4.8 g), Kostajnica VI. The yield of the tested chestnut trees was
on average (76.3 kg / tree). The selected trees Kostajnica II (66.0 kg /
tree), Kostajnica I (69.0 kg / tree) had the smallest yield and Ostros VI
(94.0 kg / tree) and Ostros V (87.0 kg / tree) had the highest. Obviously it
can be concluded that population genetic variability is very high and gene
expression is highly affected in tested samples on both locations. For
further research it should be given attention to investigate genotypes in
controlled conditions, the best in vitro in tissue culture.
