E.R.J. KELLER, A. SENULA and H. SCHULZ Some of the most famous hybrids have been produced between Allium cepa and A. fistulosum, others with A. galanthum Kar. and Kir., A. pskemense B. Fedtsch., A. roylei Stearn, A. nutans L., A. chinense G. Don, and A. ampeloprasum (KELLER et al. 1996 PETERKA et al. 1997). The situation within the Institute of Plant Genetics and Crop Plant Research (IPK) hosting the world’s largest special collection of Allium (FRITSCH 2001) encourages the direct utilisation of this broad diversity. Thus, own efforts were made between 1991 and 1993 to obtain hybrids with the help of in vitro embryo rescue. The hybrids have been included in the field and partly into the in vitro collection to be preserved for further utilisation. Recently, first steps were made to characterise these hybrids and to prepare some of them for further utilisation. Results Successful hybridisation of Allium species in the IPK Genebank A. carolinianum DC. × A. porrum L. A. cepa × A. albidum Fisch. ex M.Bieb. A. cepa × A. altaicum Pall.

A. cepa × A. sphaerocephalon L. A. obliquum × A. hymenorrhi<strong>zu</strong>m Biochemical hybrid analysis As could be shown in some cases, the biochemical properties of the hybrids may possess intermediate heredity like many morphological characters (SCHULZ et al. 2000 a, b). Sometimes the contents of interesting compounds in the hybrid may be as high as in one of the parents. This is an encouraging finding for further studies to use hybrids directly as material for medicinal purposes. Virus infection in Allium species and hybrids The virus susceptibility and, therefore, the infection is different depending on the species. High virus susceptibility may be the cause of extinction of some species in the collection. Hybrids inherit susceptibilities from the parents, e.g., to SLV from onion and to LYSV from A. albidum and A. obliquum, respectively (SENULA et al. 2000). The test antibodies for this study were kindly provided by BBA Braunschweig. 275
