lems in cucumber growing in Serbia as well as in other parts of the world
(METWALLY and WEHNER, 1990).
Finding and identifying the selection material for these, economically
most important diseases is of the greatest priority. The use of chemicals in
cucumber protection of downy has reached emergency proportions. This
too can be overcome only by breeding resistant genotypes in organic sys-
tems of production. Today, the Institute for Vegetable Crops has cucumber
lines that are highly tolerant to downy mildew in conditions of spontane-
ous infection.
The Institute for Vegetable Crops in Smederevska Palanka possesses a
collection of cucumber germplasm consisted of over 100 divergent geno-
types that are included in our breeding programs. Pickling cucumber hy-
brid characterized with high tolerance to this plant pathogen was created
using experimental crossings. Based on the results from the trial at the
Institute for Vegetable Crops, the pickling cucumber named Sirano F1 is
marked as the pickling cucumber hybrid that is the most resistant to blight
(PAVLOVIC et al., 2006).
10.3.2 BULB VEGETABLES SELECTION
Garlic draws more and more attention as an industrial plant and its produc-
tion is perspective. Garlic is characterized by high contents of dry matter,
proteins, fats, carbohydrates, vitamin C, thiamine, and B6. Furthermore,
garlic is rich with minerals such as: Mg, Zn, Mn, Cu, Mo, and Se. It also
possesses high energy values that can be paired with members of Fabaceae
family. Through the new breeding programs, the chemical structure of gar-
lic is emphasized. Based on detailed chemical analysis the best ecotypes
are selected. The aim of the research was to create the ecotypes with the
most favourable chemical composition, which would give valuable contri-
bution to the process of utilization of this vegetable variety (PAVLOVIC
et al., 2003a).
High biological value of onion is the result of its specifi c chemical
composition dominated by sugars, vitamin C and characteristic ethereal
oil. According to the average contents of vitamin C in bulbs (32.46 to
44.03 mg %), onion is a signifi cant natural source of this vitamin. In our
