Agroscope noted significant breeding progress in the variety tests with 30 new cultivars and 24 already recommended varieties of red clover (Trifolium pratense L.) conducted at six locations from 2011 to 2013. Yield, vigour, juvenile development, resistance to leaf diseases, winter-hardiness and persistence were all evaluated. For the persistent varieties (Mattenklee type), results allowing for recommendation were obtained by the diploids TP 0425 and TP 0445 as well as by the tetraploids TP 0645 and TP 0486, whilst in the short-lived varieties (common red clover), success was achieved by the diploids Bonus, TP 0725, Regent, Harmonie, AberClaret, Garant and Dimanche, and by the tetraploids Magellan, Hammon and Atlantis. The new cultivars TP 0425, TP 0445, TP 0645, TP 0486 and TP 0725 have yet to pass the test for distinctness, uniformity and stability of traits before they can be recommended. The varieties Corvus, Larus, Suez, Slavoj, Sigord and Maro no longer satisfy the requirements, and are being deleted from the List of Recommended Varieties of Forage Plants. They may, however, still be used as recommended varieties until the end of 2016.
