This project is aimed at evaluation and recommendation of rootstocks that are useful for production of avocado on saline soils. Rootstocks identified as salinity tolerant and that also meet criteria with respect to productivity and Phytophthora resistance from other related projects will be recommended for commercial release. Rootstocks with high salinity tolerance are also being incorporated into the breeding program. Results of this research will allow growers to use irrigation water having a higher salinity content than is currently permissible for avocado production.Salinity Tolerance in Avocado
