Melon is an annual, cross-pollinated species belonging to the family of Cucurbitaceae. Melon
plants are usually monoecious: male and female flowers develop on one plant, but most
commercial varieties and hybrids are andromonoecious, and on their plants develop male and
hermaphrodite flowers. On melon plants, male flowers appear first, and then develop flowers
with female reproductive organs. In this experiment, eight melon genotypes (parents), of which
four were monoecious (Sesame, ED-3, ED-4, Pobeditel), and four andromonoecious (Chinese
muskmelon, Anannas, Honey dew, A2-3lb), and their 20 hybrids (monoecious) were used. The
experiment was conducted in Smederevska Palanka, during two vegetative seasons. Seven
characteristics related to sex expression were observed. The aim was to determine the parents
with the best general combining abilities (GCA) and to determine the heterosis in their hybrids
for all seven observed traits. Negative heterosis for the trait period from sowi...ng to the emergence
of the first perfect/pistillate flower was recorded in 16 of 20 genotypes. A reduction of the period
between the appearance of male (positive heterosis) and perfect/pistillate flowers on plants
(negative heterosis) was found in 12 hybrid combinations. It was found that in as many as 17
hybrid combinations, the fruits ripen earlier than their parents. All eight observed parental
genotypes showed significant GCA values for most of the observed traits. The results showed
that the Sesame was the best general combiner, and represented a potential source of the desired
alleles required for the melon breeding programs.
