Summary
Among 70017 seeds in progenies of crosses from 23 interdihaploids with aS. phureja clone, homozygous for the seed marker ‘embryo spot’, 2 parthenogenetic monohaploid, 18 dihaploid and 3 tetraploid plants were detected. It is postulated that they have arisen from reduced, unreduced and doubled unreduced unfertilised egg cells.
