CORRELATED RESPONSE OF IN-VITRO REGENERATION CAPACITY FROM DIFFERENT SOURCE OF EXPLANTS IN CUCUMIS-MELO

The variation among and within different populations of the regenerati on ability from leaf, cotyledon and hypocotyl explants has been studie d. A control population and two lines selected by their regeneration c apacity from leaf explants were Significant differences among the plan ts of the population,for the organogenic response, were detected. The regeneration capacity varies depending on the type of explant. Selecti on in order to improve the regeneration frequency from leaf explants a lso raises the organogenic response in the other explant types. This r esult suggests the presence of a partial common genetic system control ling the regeneration frequency of the diverse types of explants.
