Nowadays increasing value is attached to husked cereal species suitable for organic farming, particularly genetic sources of the resistant diploid einkorn. Their direct use in breeding is greatly hindered, however, by the fact that the lots stored in various genebanks are generally very heterogeneous populations, making it difficult to carry out genetic studies on their agronomic traits. At the same time, suitable methods are not yet available for the in vitro androgenesis of einkorn. If homozygous lines are to be rapidly produced, methods must be developed whereby genetically pure breeding material can be developed reliably, in adequate quantities. Data in the literature suggest that in the case of einkorn this can be achieved by the "delayed pollination" of genotypes with adequate induction ability ("haploid inducers") (Kihara 1980). The present work was aimed at identifying suitable genotypes in the einkorn collection in the Martonvásár Gene Bank, with the help of which the efficiency of m situ haploid induction can be examined from the practical point of view. The data indicate that among the einkorn lots tested, two populations are suitable for in situ haploid induction and that the frequency of induction is sufficient for practical purposes.
