title: Reaction of Trifolium repens Cultivars and Germplasms to Meloidogyne incognita.
abstract: Ten cultivars and 13 germplasms of white clover (Trifolium repens) were evaluated in the greenhouse for resistance to the southern root-knot nematode, Meloidogyne incognita race 4. One hundred plants of each cultivar or germplasm were rated for percentage of the root system galled (PRSG) at 60 days after inoculation with root-knot nematode eggs. Tillman (9%) and SRVR (19%) had the highest percentage of resistant plants (PRSG = 0 or 1 on a scale of 0-5 ) for the cultivars and germplasms, respectively. No resistant plants were selected from the cultivars California Ladino or Sacramento, or from the germplasms Brown Loam population or Brown Loam Synthetic #6. Resistant plants identified in this study were used to initiate are current selection program for resistance to M. incognita.
