The androgenesis of pepper (Capsicum annuum L.) is very limitating process and it is followed by many inhibitory factors such as: pepper genotype; the structure and the stadium of microspores i.e. microspores are suitable for
the induction of androgenesis in the phase of first pollen mitosis or just before it; the genetic predisposition for somatic embryogenesis; the hormonal regulation in vitro condition; growth conditions; and many others. Science does
not have enough explanations for all known and unknown limiting factors of this process in the species of Capsicum genus. The inhibitory influence of secondary metabolites, especially capsaicin, is not explored at all, but in the
literature there are data that some pepper genotypes as bell-shape and sweet ones have higher androgenetic potential than the hot genotypes.
The results from the present research work, performed on nine varieties of pepper which differ in spicy, showed that the androgenetic potential of the pepper in anthers culture is dependent on the capsaicin contained in the fruits
of the pepper. Most probable the genetic predisposition for synthesis of secondary metabolites - capsaicin, beside all the other factors is also inhibitory trait of the somatic embryogenesis of the pepper.
