Abstract/Summary

The genus Capsicum has 20-30 species, of which only a few are cultivated. Capsicum annuum L. is the best known Capsicum all around the world, while the other species are not common outside Latin America. Since it is the best known and commercially the most valuable species, many breeding programs have been conducted on C annuum L., especially on the non-pungent vegetable types. Breeding of other species has received less attention. Therefore, this work was conducted on two species other than C. annuum that are rarely studied-C. baccatum and C. cardenasii. Other results concern linkage groups and association of the marker genes or linkage groups with the chromosomes involved in an interchange. Linkage was detected for two pairs of genes only; these were between Got-1 and Idh-1, and between Pgi-2 and Est-5. No gene was found to show a statistically significant association with chromosomes with interchanged segments.
