Abstract:

In order to obtain commercial hybrids to this species strictly cross-pollinated plant, it is highly important to maintain the parental lines used in hybrid combinations.

In the overcoming of the difficulties raised by the conservation of the vegetal material, specialists appeal most often to “in vitro” cell and vegetable tissue cultures. This technology allows the regeneration of a large number of plants, independently of season, in controlled conditions. The maintenance of such “in vitro” cultures is not expensive and the vegetal material thus obtained is authentic, homogeneous, healthy, high quality and productivity (efficiency) avoiding the phytosanitary risks and the early biological cycles. (1, 2, 3, 6)

In our experiment, we obtained the recovery and the maintenance of some parental lines practically lost, starting from some seeds without germinal capacity in normal sowing conditions.
