Abstract
The investigations, descriptions and evaluations of morphological and ornamental properties of Iris cultivars were carried out in the period of 2011-2013 according to the requirements of the International Union for the Protection of New Varieties of Plants (UPOV), Biodiversity International (BI) and methodologies used in neighbouring countries.
At present in the collection of the Vilnius University Botanical Garden there are more than 300 iris cultivars of both foreign and Lithuanian origin. 117 of them have been studied.
The goal of the study was to prepare a descriptor of bearded irises.
The most suitable parameters to describe the vegetative part of the iris are: plant height, plant branching, leaf colour, colour of the leaf rosettes bottom, leaf length, leaf width, and leaf blade.
For the evaluation of the generative part the best parameters are: beginning of butonization, strength of the flowering stem, types of inflorescence, number of blossoms in the inflorescence, flowering duration, bloom size, growth characters of the petals, petals width, bloom colour, colour of petals, expression of longitudinal veins of lower petals, petal edge, beard colour, and bloom smell.
For the first time in Lithuania botanists, specialists of Botanical Gardens of Lithuania, flower plant breeders, plant collectors, the researchers of plant cultivars, flower growers and farmers will be able to use the developed methodologies for Iris description, investigation and evaluation of biological, morphological properties.
