Genetic improvement can take many approaches to improve cultivars, each with their own advantages and disadvantages. This paper will discuss several approaches used in the genetic improvement of mangoes in Australia, including varietal introductions, selection of monoembryonic progeny, selection within polyembryonic populations, assisted open pollination and controlled closed pollination. The current activities of the Australian National Mango Breeding Program will be outlined, and the analysis and use of hybrid phenotype data from the project for selection of next generation parents will be discussed. Some of the important traits that will enhance the competitiveness of future cultivars will be introduced and the challenges in achieving them discussed. The use of a genomics approach and its impact on future mango breeding is examined.

Calcium, N and crop load were chosen because previous research and Gower reports implicate them as major factors in internal disorders, poor colour development, and postharvest disease in mangoes grown in the Mareeba district of Queensland. The symptoms and incidence of the internal fruit disorders seen in Keitt mangoes growing in Queensland were investigated to determine their similarity to other forms of internal disorders, and to develop a severity rating scale to assess fruit in later experiments. While the observed disorder in Keitt shared some symptoms with other named forms of disorders, not all symptoms were similar. The typical symptoms of patches of watery translucent flesh that breakdown and discharge cellular fluids in the more severe cases, ar...

Pre-harvest management, especially nitrogen (N) nutrition, appears to be a major causal factor. To obtain an understanding of the extent of the problem in the Burdekin district (dry tropics; the major production area in Australia), green mature ‘Kensington Pride’ mango fruit were harvested from ten orchards and ripened at 20 ± 0.5 O C. Of these orchards, 70% produced fruit with more than 25% of the skin surface area green when ripe. The following year, the effect of N application on skin colour and other quality attributes was investigated on three orchards, one with a high green (HG) skin problem and two with a low green (LG) skin problem. N was applied at pre-flowering and at panicle emergence at the rate of 0,75,150,300 g per tree (soil applied) or 50 g per tree as foliar N for the HG orchard, and 0,150,300,450 g per tree (soil applied) or 50 g...
