BREEDING MANGOES FOR AUSTRALIAN CONDITIONS
Opportunities exist through breeding to develop a new cultivar which retains the characteristic flavour of ‘Kensington’ but has improved productivity, greater disease resistance, enhanced skin colour and better post-harvest performance. These features are found in the Florida cultivars, viz. ‘Irwin’, ‘Sensation’ and ‘Tommy Atkins’, which are being used as maternal parents crossed with ‘Kensington’.
Investigations have shown that the dominant leaf and fruit volatile in ‘Kensington’ responsible for its unique flavour is terpinolene. Characterisation of leaf volatile profiles using gas chromatography and mass spectrometry (GC/MS) has shown significant differences between cultivars. This technique has potential for the identification of genetic re-combination in progeny, particularly with respect to the detection of significant concentrations of terpinolene.
