The main task of breeding red clover, the second most important perennial forage legume, is to develop cultivars giving high forage yields of excellent quality. Goals set before red clover cultivar development are achieved by different breeding methods. Previous research has shown that the most important methods used in red clover breeding are mass selection, individual selection, recurrent phenotypic selection, the polycross method, hybridization, and polyploidy. Mass selection is one of the oldest methods and has proven highly effective in improving highly heritable traits. Individual selection and hybridization have been shown to be highly effective in increasing protein content. Recurrent phenotypic selection is very effective when breeding for resistance to some diseases and pests as well as when developing genotypes tolerant of the 2,4-D preparation. The main idea behind the polycross method is selection of clones with a good GCA to be used for developing improved synthetic cultivars. Since no tetraploid forms of red clover have been discovered in nature, induced polyploidy receives special attention in the breeding effort, mainly for the purpose of increasing forage yields. .
