Genetics of Self-Compatibility in Dihaploids of Solanum Tuberosum L. 5. The S-Genotype of Tetraploid Potato Cultivar Gineke. - Euphytica, 27, p.385-388, 1978 .

Investigations of the genetics of self-compatibility and self-incompatibility in dihaploids and diploid derivatives from cv. Gineke revealed the presence of S1, S2 and S3 at the S-locus of Gineke and in addition an S1-allele on a translocation. By means of a complete tester set involving the S-alleles S1, S2 and S3 (all from Gineke)and S4 (from Black 4495)it was demonstrated that some Gineke dihaploids were compatible with all six testers. This indicated a fourth S-allele in Gineke, which differs from those in the tester series and was therefore assigned S5. Additional evidence was obtained from an analysis of F1's from crosses of two S5-bearing dihaploids and one of the testers. So the S-genotype of cv. Gineke was identified as S1S2S3S5/S1, the second S1 being the S-allele on a translocated fragment.
