Analysis of intra-specific somatic hybrids of potato Solanum tuberosum using simple sequence repeats. The production of somatic hybrid plants with a chromosome number deviating from the expected is well documented in many fusion combinations where potato protoplasts have been used as one fhsin both fusion parents Austin et al.

Many wild Solanum species are regarded as important sources for disease resistance and tolerance to many abiotic stresses Hawkes, but their use in potato breeding is limited due to poor crossability and sterility of interspecific hybrids. The wild species S. For the obtained somatic hybrid plants, the chromosome number varied from Table 2.

When colonies had developed, alginate beads were despolimeryzed using 20 mM sodium citrate solution in sorbitol 0,3 M, pH 7,4 and gently shaking. Nineteen plants were regenerated from calli Fig.

Under these conditions, calli hybrids follow the developmental pathway of the morphogenic parents. Microcalli were transferred onto MS medium to induce fsin regeneration under indirect light conditions.
