Breaking the disease cycle, through the use of lines of L. rigidum resistant to the nematode Anguina funesta can be used to reduce th risk of ARGT outbreaks. In L. rigidum, resistance to A. funesta appears to be under the control of two unknown, but complementary genes. This study explored alternate approaches towards the allocation of genotype for lines of L. rigidum with respect to resistance to A. funesta. / Thesis (Ph.D.)--University of Adelaide, Dept. of Applied and Molecular Ecology, 2003
