Differences in persistence in red clover cultivars as an important trait for their use in permanent grasslands

Popis výsledku v původním jazyce

Red clover distinctly increases herbage quality and production of temporary and permanent grasslands at low fertilization requirements. Main disadvantage of this species is insufficient persistence. Once the plants in the 2nd or 3rd harvest year disappear, the remaining grass sward needs more nitrogen fertilizing, overseeding or renovation. Hence the breeder's effort is focused on improving persistence of new red clover cultivars. In the trial dry matter production of forage and proportion of eight tetraploid and fourteen diploid cultivars of red clover grown in mixture with grasses were assessed. The highest DM forage yield in the 3rd harvest year reached Swiss cultivars Astur, Milvus and Pavo, followed by the German cultivar Lucrum and Christie (Can). The ratio between the yields in the 3rd and 1st harvest year is another indicator of cultivars persistence. The highest ratio was realized at the cultivar Astur (1.13), Pavo (0.94) and Lucrum (0.94). The productivity and persistence of
