Ilieva, A. | Radeva, V. (Forage Institute, Pleven (Bulgaria))
The study was carried out under controlled conditions and provoked drought with 3 alfalfa regenerant lines R1.2, R2.4, R1.1.In the study of adaptation abilities the regenerat lines were compared with the initial form T1 by content of amino acids, free proline and plastid pigments.It was found that the lines R2.4 and R1.2 with better adaptation ability in comparison with T1 are superior to it by content of total and essential amino acids, free proline.They are with less decrease of the content of plastid pigments.The regenerants R2.4, R1.2 which are close to the initial form T1 by morphology and productivity and have better adaptation ability than it, are incluuded in a polycross plot for development of a synthetic variety.
