Abstract
The role of mutation breeding in ornamental plant breeding has increased significantly in recent decades.
Within mutation breeding, gamma radiation is a very effective method, as phenotypically different variants can be created relatively easily.
And this will be very necessary in the future, as the trade in ornamental plants constantly requires new cultivars, and in addition, due to climate change, cultivars resistant to abiotic stress are becoming more and more important. Rudbeckia hirta L. has long been a very popular species in urban landscaping. Rudbeckia hirta is officially an annual species, but it can be grown as a short-lived perennial in several countries – mainly due to climate change since increasing global warming.
The famous Hungarian Rudbeckia hirta cultivars create a very rich gene bank for breeding.
The plants created during different doses of gamma radiation can be suitable as the genetic basis of new cultivars.
In our measurements, we used different doses of gamma radiation, and we subjected the variants to morphological, histological tests.
The aim of our studies is to breed new cultivars for public areas that can withstand the current climate.
