Enhancing fruit size

Fruit size is a commercially important trait and is determined by the extent of fruit growth. Research in a UGA horticulture laboratory aims to understand the mechanisms of regulation of fruit growth in crops such as apple, peach and blueberry. Multiple candidate genes affecting cell production and thereby fruit growth have been identified and are currently being characterized. The effects of production practices on fruit growth and development are being evaluated. This information may be useful in developing cultivars with optimum fruit size and for fine-tuning fruit production practices. This can lead to enhanced fruit size and overall profitability for fruit growers in Georgia.
