Summary
The results from an experiment designed to investigate the possibility of an effect of incompatibility genotype on the level of pseudo-self-compatibility gave little or no evidence of such an effect among the members of three pairs of perennial ryegrass families. The plants of one of these pairs of families, however, set a little more seed than those of the others both in this and a previous experiment which indicates an effect of the genetic background on pseudo-self-compatibility.
A revision of the classification of four plants of a previous experiment (Cornish et al., 1979) shows that the genotype of F4 is S1·1Z1·4 and that the genotype of F3, G11 and G13 is S1·2Z2·3.
