This investment is evaluating the performance of new commercial and public rootstocks from global programs for the Australian citrus growers, with a focus on improving the yield and quality of both fresh and processing fruit, boosting tree health by improving tolerance to stresses, and looking at the modification of tree architecture. The goal is to evaluate the performance, including product quality attributes, of locally-adapted rootstocks to Australian growers, suited to both mainstay and new citrus varieties. The work will ultimately allow growers to intensify plantings, modernise orchards and obtain higher yields with minimal extra inputs, while meeting requirements for existing and emerging markets.
