Citrus Rootstock Breeding and Evaluation

The objective of the citrus rootstock breeding project is to provide the California citrus industry with a wider diversity of rootstocks that improve productivity and profitability. The current range of rootstocks does not provide good choices for specific conditions, such as calcareous soil types, long-term compatibility with mandarins and lemons, strong resistance to all citrus nematode biotypes and tolerance or resistance to new threats such as Diaprepes root weevil.
