Abstract: Head cabbage androgenic genotypes of R1 and R2 generations derived from Jaguar F1 donor hybrid wereevaluated according to their agroeconomical characters, ability for generative propagation, self-incompatibility,intraline uniformity and stability of morphological characters. Most of R1 and R2 genotypes had desiredmorphological characters. However, in R1 generation 21 lines showed lack of internal uniformity probably due tothe somaclonal variation. Genotypes of R1 and R2 generation from different embryos were more diversified thangenotypes derived from the same embryo according to self-incompatibility, ability for seed setting, vegetativeperiod, head shape, internal sump length and mass of head. Rigid selection of androgenic material at R0, R1 andR2 pedigree according to absence of somaclonal variation, agroeconomical traits, self-compatibility and seedsetting ability seemed to be crucial for the deriving stable and suitable for the breeding genotypes of headcabbage.
