Preliminary Results Regarding the Use of Interspecific Hybridization of Sunflower with Helianthus argophyllus for Obtaining New Hybrids with Drought Tolerance, Adapted to Organic Farming

Taking into account the climatic changes expected in the future, significant shrinking of the current favourable ecological zones for sunflower is anticipated, and the transition period to that situation may be very short. The classical breeding process has a relatively long duration (7-9 years), so breeders are interested in taking advantage of some biotechnological methods (embryo rescue) for obtaining new sunflower lines with increasing tolerance to a certain stress factor.
