| Abstract:
The primary breeding objectives for avocado include production problems associated with clonal rootstocks and with scion varieties. As part of an integrated approach for improving avocado with biotechnology tools, rootstock and scion selections are being genetically transformed in order to address some breeding objectives. The objectives include: 1) control of Phytophthora root rot disease of avocado rootstocks; 2) suppression of ethylene biosynthesis to control fruit ripening and to stimulate on-the-tree fruit storage of West Indian avocados; 3) control of fruit and foliage fungal disease, e.g., anthracnose; 4) control of avocado sunblotch disease. These strategies complement somatic hybridization, in vitro mutation induction and conventional breeding studies for avocado cultivar improvement. | |
