✦ Synopsis

brief survey is given of the genetics of self-compatibility in species with a one-locus gametophytic system of incompatibility . study has been made of the genetics of the self-compatibility found in L. peruvianum .

From the results of various test crosses and selfings and of cytological research it is concluded that self-compatibility in L . peruvianum can be based on different types of S-allele mutations, on addition of an S-allele bearing chromosome fragment, or on genes modifying the S-allele expressivity .

The results further indicate that generation of new S-alleles is a frequently occurring phenomenon in inbred material of L . peruvianum and that pollen with an S-allele mutation or an extra chromosome fragment is less vital than normal pollen . short notation for incompatibility genotypes is given .
