Abstract

At the Institute for Fruit Breeding in Dresden, anther and microspore culture and in situ parthenogenesis were used for successful haploid induction in apple.
At present, 107 lines of 9 different donor genotypes exist in vitro and 50 of them have already been transferred in situ. Determination of the ploidy level, by means of flow cytometry, demonstrated a distribution of diploid, triploid and tetraploid levels for the regenerated lines of one single donor genotype.
Using segregating isozyme loci as markers, 93% of the lines were found to be definitely homozygous.
Out of 30 lines of scab resistant donor genotypes, tested by PCR-analysis, 24 demonstrated the SCAR-Marker ALO7 linked to the Vf-gene for scab resistance from Malus floribunda.
