Abstract
In research on androhaploids in the progeny of interspecific hybrids within the Capsicum genus, three genetically stable lines of F7 generation, selected from the C. annuum L. × C. chinense Jacq. hybrid, were used. In the first line, only callus tissue was formed as a reaction to the conditions of culture. Cytometric analysis of this tissue revealed the presence of cells with DNA content in nuclei at the level of 1C to 16C. The tissue was mixoploid and non-embryogenic. Anthers of the other line did not respond. In the third one, nine embryos were obtained, and they developed into plants. By means of cytometric analysis, the 1C DNA level was found in eight of them and these were androgenic plants. The origin of one of the diploid plant was not established due to the homozygous character of the donor plants. The experiment results confirm the already known diversity of genotype reaction to the conditions of culture. It moreover point to the possibility of selection of the forms with an androgenic potency from interspecific hybrids.
