Approximately how many varieties of strawberries exist?

The correct answer, which indicates that there are over 600 varieties of strawberries, is supported by the fact that strawberry cultivars have been extensively developed and diversified since their domestication. These varieties are categorized based on factors such as fruit size, shape, color, flavor, and growth habits. The development of hybrid and specialty varieties has also contributed to an increase in the total number of types available.

While options suggesting fewer varieties may reflect a more limited understanding or generalization of known types, they do not encompass the full spectrum of strawberries cultivated globally, especially considering the ongoing horticultural developments and breeding programs that create new cultivars each year. This variety is essential for different agricultural practices, markets, and consumer preferences across various regions.
