Assessment of biomorphological and economically valuable traits of Iris ×hybrida hort. varieties of the collection of N.V. Tsitsin Main Botanical Garden of Russian Academy of Sciences for subsequent hybridization in the conditions of Central Russia

Every year, new zoned varieties appear that meet the natural and climatic conditions of a particular region. Due to the fact that most varieties of irises are bred in countries with a warm climate, there is a need to create domestic varieties that are not inferior in decorative qualities to the latest varieties of foreign breeding. As part of the study, a comparative study of Iris ×hybrida hort varieties was conducted according to such traits as resistance to diseases and pests, abundance of flowering, pollen fertility, plant height, number of flowers on the peduncle, length and width of the flower. The Gold of Canada is used as a standard variety. According to the results of our study, the varieties with the highest breeding index reflecting the presence of all the studied characteristics were identified.
