Brief characteristics of the exhibit
Variety Pramedi was bred out by interspecific crosses between tetraploid red clover (Trifolium pratense L.) cv Tatra (2n=4x=28) and zig- zag clover (Trifolium medium L.) ( 2n=8x=64). We can recommend Pramedi to use as a forage crop on arable land in pure stands or in mixtures with grasses either for direct cattle feeding or for conservation by silage making. Pramedi is also possible to use as a component of grass clover mixtures for long term meadows.
Specification of advantages compared to the competitors
The variety Pramedi is the first hybrid variety of T.pratense x T. medium within Europe or probably all over the World. Pramedi showes more stems (by 20 in average) per plant in comparison with tetraploid red clover. It is caused by the fact that Pramedi root neck showes more branches tan that of red clover. We could also found out rhizomes in the Pramedi root system, whilest they are not presented in red clover root system. As to forage quality it is possible to state that Pramedi showes higher content of nitrogen, digestible nitrogen, water soluble carbohydrates, PDIN - nitogen digested in small intestin, NEL, NEV - netto energy of lactatin, netto energy of (výkrmu), ME - metabolizided energy and it also reaches higher PPO (polyphenoloxidases) content. At the same time Pramedi showes lower sum of flavonoids content compared to red clover cv Amos.
