Abstract

Genes conferring host resistance to an obligate parasite, grouped together in complex loci provide opportunities to study their structure. By means of an appropriate operational definition of these genes, a modified cis-trans test was used to interpret the position effects of codominant genes mutually recombined within each of two complex loci of flax, with the use of a specially developed method of analysis among F(2) segregants. The different behavior of genes in the M and L groups may reflect a difference in their structure sufficient to raise important implications in the theory of specific host-parasite interactions.
