| Description | Trifolium pratense is a high-yielding and high-quality fodder crop but shows a low persistency, which may be overcome by hybridisation with species that produce rhizomes. The aim of this study was to evaluate 16 characteristics in the hybrid plants derived from F1 hybrids between T. pratense and T. medium and in both of the parental genotypes. The characteristics were evaluated in 500, 745 and 112 hybrid plants in three years. There were significant differences between the hybrids and T. pratense in nearly all of the analysed characteristics. The stem number per plant was significantly higher in the hybrids compared to both parental species, which could have a positive impact on the yield. Short rhizomes were observed in the hybrids after the harvest of the plants in the second harvest year. This trait will be studied from the viewpoint of improved persistency. The variability useful in breeding was significantly increased in resulting genotypes. |
