given almost no serious horticultural attention. Researchers should now scour the Andes as well as New Zealand, South Africa, Hawaii, and other likely places for the sweetest and most pleasant types. Superior strains should be documented. The greatest variation is likely to be found along the Andean cordillera. Selection for growth habit, stable characteristics, and superior fruit types can probably best be accomplished in this region. In particular, a determinate cultivar, whose fruit mature all at once, would be valuable for intensive agriculture. Selecting plants whose shapes are amenable to mechanical harvesting would als be a major advance.

Fruit Quality Much could be done with producing color variations. Fruits that are striped, variegated, and oddly shaped have often been observed, but so far have not been developed.

It is easy to select for larger berries, but these tend to split during transport. Overcoming splitting would be an important factor in advancing the crop. The causes of splitting should be investigated.

Postharvest handling and improved methods of shipping, harvesting, and storing goldenberries would allow a greater return to the grower and a more satisfied consumer. (The techniques used for handling tomatoes might apply here. For example, the use of ethylene might be employed to force uniform ripening.)

Agronomic Research Techniques of pruning that adapt the plants to mechanical harvesting could increase yields while lowering the costs of production in countries where labor costs are high. Also, modern trellising methods (as used with pepino, for example) should be tested.

There is little practical understanding of pests and diseases. Baseline studies are needed.

Applying to the goldenberry the tissue-culture techniques developed for tomatoes and potatoes may open up avenues for the rapid propagation of desirable cultivars with predictable performance.

The use of hormones to induce fruit set and increase fruit size should be explored.

End-Use Research Additional research is needed on the vitamin and mineral content as compared with other berry fruit. It seems likely that nutritional quality could become a valuable tool in promoting the goldenberry.

Research is also needed on new uses for the processed fruits, especially in products that ship and store well—for example, marmalades, preserves, and jams—but also in wine, ice cream, milk shakes, yogurt, and toppings for desserts and cakes.
