Potential acreage of berseem clover has been increased by the recent release of ‘Bigbee’ berseem clover ( Trifolium alexandrinum L.). Bigbee berseem clover was evaluated to determine if root‐knot nematodes ( Meloidogyne arenaria, M. incognita , and M. javanica ) may be a limiting factor in new berseem production areas compared with other legumes with similar geographic adaptation. Root‐knot nematode interaction with 15 other germplasm sources of berseem clover was also evaluated in at least one of three separate tests. Eight berseem germplasms were severely galled by the mixed population of Meloidogyne spp. present in the field test. All nine germplasm sources of berseem clover, including Bigbee, were severely galled by M. arenaria , M. javanica , and M. incognita race 3 in the two greenhouse experiments. Gall scores were not significantly different than for the known susceptible host ‘Amclo’ arrowleaf clover ( T. vesiculosum Savi.), but were signficantly more severe than for ‘Dixie’ crimsom clover ( T. incarnatum L.). ‘Florida 77’ alfalfa ( Medicago sativa L.) proved to be highly resistant to all three Meloidogyne species studied. Field investigations are needed to determine if root‐knot nematodes would limit the production of Bigbee berseem clover similarly to the way they limit production of arrowleaf clover.
