Interspecific Hybrids

Biology and Chemistry of Jerusalem Artichoke Helianthus tuberosus L. 

In many instances, the success of interspecific hybrid crosses is limited, although with embryo culture it can often be improved. In a range of crosses, the success rate was increased using a two-stage technique (Chandler and Beard, 1983). The embryos were initially developed on a solid medium, for germination, and then transferred to a liquid medium. Embryos were excised and cultured for 3 to 7 days.

Some wild species have larger capacities for osmotic adjustment, a trait which may improve yield during drought (Table 3, Turner, 1986). Interesting examples of this are Dubautia species from Hawaii which differ in osmotic adjustment mainly as a result of differences in cell wall elasticity. Interspecific hybrids can be made which have intermediate properties (Robichaux, Holsinger Morse, 1986). Material such as this could make a basis for the molecular study of differences in cell wall elasticity.

GPRT- defective cells appear in population. Using the method of the selective pressure by 5-BDU and 8-Ag, the mutant cultures of cells, defective by the indicated enzymes, are obtained. The intraspecific and interspecific hybrid cultures of cells are firstly obtained in the laboratory of the cellular biotechnology, A4H (SPEV TK- x lymphocytes of horse) and others. Hybrid cultures possess the unique properties. They are the ability to grow in the monolayer and in suspension, the high sensitiveness to the viruses. Hybrid cultures PO-TK-KHLO, PO-TK-KHSO are sensible to the agent scrappy, what allows using them for the study of diseases, caused by prions.

In plant breeding, obtaining interspecific hybrid is important for introducing desirable genes from wild species to cultivated species. However, it is very difficult to obtain a viable hybrid plant between widely related species. These problems would predominantly come from sexual reproduction such as cross incompatibility, hybrid inviability, etc [118,119].

We continue our Geisenheim program to breed interspecific varieties besides our broad vinifera-breeding activities and clone selection. . . We are convinced that interspecific hybridization will be fundamental to vine improvement though the German legislation presently will not allow to recommend and plant grape vines which are not vinifera.
