Abstract
The Australian fresh market pineapple breeding program commenced in 1991 with the objective of developing clones more suited to fresh consumption than the industry standard clone, ‘Smooth Cayenne’. These early crosses developed approximately 60,000 seedlings from which the 2 cultivars ‘Aus-Jubilee’ and ‘Aus-Festival’ have been commercialised.
Plant Breeders Rights have been used to protect intellectual property.
A second program which commenced in 2010 has utilised selections from the first program as parents to produce a segregating population of 20,000 seedlings.
This second program includes many half-sib and backcross combinations to concentrate the frequency of desirable genes quicker.
Current breeding objectives include sweet, low acid and low fibre, aromatic eating qualities with a low susceptibility to translucency and internal fruit disorders.
A good level of resistance to Phytophthora root rot and natural flower initiation is also sought.
