[Chiasma frequencies in the meiocytes of anther diametrical sections in Capsicum species].
Investigations concerning chiasma frequencies in meiocytes of three anther zones (free end, middle, base) in the cultivated and wild species of Capsicum genus have been carried out. It is revealed that maximum indices of total chiasma frequency were observed in the anther free end in comparison with its middle part and base. The conclusion is drawn that regularities of distribution of recombination indices are the result of the anther anatomy structure.
