โœฆ Synopsis

Investigations of the genetics of self-compatibility and self-incompatibility in dihaploids and diploid derivatives from cv. Gineke revealed the presence of S~, $2 and $3 at the S-locus of Gineke and in addition an S~-allele on a translocation. By means of a complete tester set involving the S-alleles S1, $2 and $3 (all from Gineke) and $4 (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 $5. Additional evidence was obtained from an analysis of Ffs from crosses of two Ss-bearing dihaploids and one of the testers. So the S-genotype ofcv. Gineke was identified as S1SzS3Ss/SI,the second $1 being the S-allele on a translocated fragment.

Two highly fertile and self-compatible dihaploids (2n 2x 24) from Solanum tuberosum L. (2n 4x 48) were investigated to elucidate the genetic basis of their self-compatibility. To this end the two dihaploids were selfed and reciprocally intercrossed and the resulting I~ and F~ plants tested for self-

Two self-compatible (SC) dihaploids, G254 and B16, and one self-incompatible (si) dihaploid, G609, from Solunum tuberosum L. were intercrossed reciprocally. Segregation ratios SC : si : pc (pseudocompatible) were determined in all 6 Fi's in three successive years and critically tested and discussed.
