The research describes the field comparison of 81 decorative sunflower
genotypes. In order to assess genetic diversity of sunflower genotypes the
studies were conducted in the field conditions during 2010-2015 at the
Institute of Field and Crops, Novi Sad, Serbia. The genetic diversity of
species Helianthus annuus L. has enabled the breeding work in the direction
of the decorating and plant landscaping. Depending on the qualitative and
quantitative characteristics, production of decorative sunflowers can be
divided into three directions. The first line is for the production of cut
flowers, the second one is for garden production and the third line is for
the production of pot plants. The direction of production dictates the main
breeding objectives, which may include: plant architecture, the color of ray
and disc flowers and duration of flowering. Investigation of the genetic
variability of ornamental sunflowers relies on quantitative traits of which
the greatest variability was observed in branching and plant height, which
are also the most important qualities for production. The quantitative
characteristics of decorative sunflowers have been examined on the basis of
81samples.
