Background Fruit quality has been identified as a major limiting factor to market expansion on both the domestic and export markets.
Surveys indicate that the major quality problems are skin blemish, flesh defects, and immaturity.
Surveys also indicate a lack of knowledge on appropriate handling and storage techniques for this highly perishable fruit. Research Research was conducted into both pre and post-harvest aspects affecting fruit quality. Pre-harvest research evaluated nutrition, in particular calcium and boron effects on internal fruit quality, and pollination effects on fruit shape and symmetry. Post-harvest research evaluated cool, modified and controlled atmosphere storage techniques and causes of fruit immaturity. Outcomes Several promising new varieties and breeding lines have been evaluated from the selection and breeding program.
