Besides producing inbred lines which have better combining ability than the present cultivars, inbreeding confers an important benefit upon potato breeding, in that it leads to a reduced heterozygosity. The need of large population for selection will be considerably lowered, if the parental material are raised which breed true for some important characters. It is impossible, however, to inbreed in usual way in male sierile cultivar such as Early Rose. In this case, haploidization provides an effective means. This study was carried out with the purpose of raising inbred lines in the cultivar Early Rose which is male sterile and presumed to have many desirable genes in view of the fact that this cultivar had been an ancestor of many present leading cultivars, and this attempt was successfully realized by means of haploidization followed by chromosome doubling.
