White clover (Trifolium repens L.) population dynamics and genetic variation were characterized in populations under continuous grazing management. RAPD (random amplified polymorphic DNA) profiles were developed for individuals sampled from managed permanent pastures on 18 farms in Pennsylvania (PA), New York (NY), and Vermont (VT). Genomic DNA from individual white clover plants (48) sampled over two transects at each location during fall, 1996, was amplified by the PCR (polymerase chain r...

	Genetic Variation within and among White Clover Populations from Managed Permanent Pastures of the Northeastern USA. Crop Science ; White clover populations in pastures at northern mid-latitudes have been naturally maintained for many decades through seedling recruitment in spring and vegetative propagation throughout summer and fall. In addition, graziers periodically broadcast seed of commercial white clover cultivars in
