Theme 14: Advances in Forage Legumes

Description

Rose clover (Trifolium hirtum All.) is a winter annual forage legume that has potential for increased use in the U.S. southern region. New cultivars of rose clover are needed with the combination of cold tolerance, winter forage production and full bloom date of late April. Crosses were made between two early flowering cultivars and one late flowering rose clover cultivar. The F2 and F3 generations from these crosses were evaluated in northeast Texas for winter growth, cold damage and date of flowering. Fourteen F3 lines, out of 37 selected F2 parents, showed large increases (>100%) in plant size on 9 Feb., relative to the late flowering rose clover parent.
