‘Fuchs-20’ (Persea americana Mill.) was selected in an experiment carried out during 1959-60 to find a highly tolerant rootstock for saline conditions from West Indian seedlings of 5 different groups and hybrids, including seedlings of ‘Fuchs’ (West Indian x Guatemalan). Plants were grown in containers and irrigated with highly saline water (1330 ppm NaCl). Only 4 plants survived. These survivors were planted in an orchard in order to obtain material for further experiments by vegetative propagation. ‘Fuchs-20’, a ‘Fuchs’ seedling marked No. 20, was the only one of these 4 plants from which cuttings have been successfully rooted (2) (350 ppmCl), (1). Trees of various cultivars grafted on ‘Fuchs-20’ rootstocks show excellent performance without any damage due to salinity in a commercial orchard irrigated with water containing 380-400 ppmCl, (A. Ben-Ya’acov, unpublished data).
‘G.A.-13’ avocado (Persea americana Mill.) was selected to provide a rootstock for saline and lime conditions.
Maoz avocado (Persea americana Mill.) was selected to provide a rootstock for high saline and high lime conditions.
