Popis:	Sexual progeny were raised from matings between 2C (diploid) × 4C (tetraploid), 2C × 2C and 4C × 4C isolates of Phytophthora infestans. The percentage germination of oospores and establishment of colonies were generally lower in the 2C × 4C and 4C × 4C crosses than in the 2C × 2C cross. Isoenzyme analysis of progeny from some matings revealed that most were hybrids but that the proportion of selfs was generally higher in 2C × 4C crosses. The fluorochrome DAPI was used to determine DNA contents in samples of all progenies. Hybrids from the 2C × 2C cross were all 2C whereas those from 2C × 4C crosses ranged from 2C to > 3C. Progenies from the 4C × 4C crosses ranged from 2C to 4C.
