Description
White clover (Trifolium repens L.) is the most important legume species used in New Zealand pastoral agriculture (Williams, 1987). However, its growth and fixation of nitrogen can be severely reduced by the root knot nematode, Meloidogyne hapla Chitwood (Widdowson et al., 1973; Yeates et al., 1973; Yeates et al., 1977). This nematode is commonly found throughout New Zealand (Mercer and Woodfield, 1986; Skipp and Christensen, 1983) Chemical control is not economic, or environmentally desirable. The breeding of resistant cul ti vars may be an effective way to reduce the effects of this pest. Resistance or tolerance in white clover should improve not only growth and nitrogen fixation, but also nutrient utilisation and drought tolerance. Screening of white clover plants against root knot nematode was initiated and broad sense heritabilities used to check on progress.
