The main objectives in ornamental sunflower breeding are different from the objectives in development highly-productive oil and confectionary sunflower hybrids. Breeding of ornamental sunflower requires desirable plant architecture, colour of ray and disc flowers, duration of flowering, etc. There are different directions within breeding of ornamental sunflower depending on their usage. Modern breeding of ornamental sunflower follows three main directions; ornamental sunflower for gardens and parks, ornamental sunflower as a cut flower; dwarf types for pot productions. Each direction has different demands and aims, but most important is to be attractive and sterile - without pollen production to avoid allergies and for aesthetical reasons. In commercial production both varieties and hybrids are used. The use of hybrids has more advantages compared to varieties because they enable higher crop uniformity, better vigour, simple breeding methods for gene introduction for diseases resistance. The aim of this paper is to show main caracteristics of five ornamental inbred lines and their crosses, as well as genetic variability and mode of inheritance for length of basal branches flowering, number of branches and length of branches.
