Abstract

The result of INTERSPECIFIC CROSSES in potato mainly is explained by endosperm balance number (EBN) or effective ploidy hypothesis. However in some of INTERSPECIFIC CROSSES the pre-zygotic barriers are also functional. In this experiment the CROSSABILITY of four wild allotetraploid 2EBN, species (Solanum acaule, S. fendlerii, S. hjertingii and S.stoloniferum) with 11 tetraploid clones belonging to two subspecies of S. tuberosum (ssp. andigena and tuberosum) were investigated. The results indicated that the incidence of pre-zygotic INCOMPATIBILITY were lower when the wild species used as pistilate parents than reciprocal crosses. Among wild allotetraploid species, S. acaule had the lowest penetration and barrier capacity and between the two cultivated subspecies ssp. tuberosum had low barrier capacity as compared with ssp. andigena. Overly from 1169 performed inter-specific INTER-EBN CROSSES four hybrids were obtained, two fromstoloniferum × tuberosum, one from hjertingii × tuberosum and one from fendlerii × tuberosum. The first three hybrids were tetraploid (2n=4x=48) and the last one was hypotetraploid (2n=4x-2=46).
