An interspecific crossing program was carried out to improve the genetic basis of garden asparagus (Asparagus officinalis L.) for resistance to biotic and abiotic stress as well as quality associated compounds. Currently, interspecific hybrids between Asparagus officinalis and A. amarus, A. maritimus, A. verticillatus as well as A. trichophyllus were generated by hand pollination and embryo rescue. In vivo established hybrid plants were analyzed using molecular and cytological techniques. The morphological characterization and chemical investigation of volatile compounds of the hybrids suggests an intermediate stage between the cross parents. Partially, the hybrids expressed a number of novel volatile compounds. Potential breeding value of the obtained interspecific hybrids and the further work is discussed.
