[Production of potato breeding material using somatic hybrids between Solanum tuberosum L. dihaploids and the wild diploid species Solanum bulbocastanum Dunal. from Mexico].
An original approach to overcome interspecific incompatibility when backcrossing the tetraploid Solanum tuberosum + S. bulbocastanum somatic hybrids with cultivated potato was realized. This method is based on the decrease in their ploidy using anther culture and involvement of the haploid producer S. phureja IvP35. The feasibility of obtaining a diploid progeny from the somatic hybrids carrying genetic material of the wild species S. bulbocastanum and crossable with S. tuberosum dihaploids was demonstrated.
