Abstract The use of plant material outside the country of
development is common, but whether such material is superior to existing types
of the same species is questionable. Seven United States and eight New Zealand
white clover (Trifolium repens) cultivars, germplasms, or breeding
populations were evaluated for plant spread and dry matter yield for two years
at Mississippi State, Mississippi, USA, when grown in monoculture or with
grasses having differing seasonal growth patterns, viz tall fescue (Festuca
arundinacea) and bermudagrass (Cynodon dactylon). Plant material
originating in the United States had 49-53% greater plant spread and 79-222%
greater clover dry matter yield in monoculture or in association with either
grass than the New Zealand material. Osceola, SRVR, and Brown Loam Syn#2 white
clover had greater plant spread than all New Zealand material at 9 of 11
sampling dates. White clover spread and yield under monoculture showed a closer
correlation with growth in association with common bermudagrass than with tall
fescue. White clover should be selected in the climate and with the grass
association in which it is to be utilised.
