Ten Polish red clover cultivars were tested in vitro for their capability to produce callus and somatic embryos. A three-step tissue culture protocol (callus induction, embryo induction and plant development) based on Gamborg's B5 basal salts, NAA and 2,4-D as auxins, and kinetin and adenine as cytokinins was utilized. Explants source were petiole and hypocotyl sections. All clover varieties under study have showed high efficiency of callus production, and low ability for plant regeneration from the callus. The highest percent of genotypes which developed embryos was observed on variety Parka (3,6). Single embryogenic genotypes were selected from nearly all varieties. Hypocotyls showed the greatest ability for callus regeneration comparing to leaf petioles.
