Variety selection is often based chiefly on personal preference, which is unfortunate. Variety selection should be driven by your marketing plans. Research the market you are planning to sell into, and the data you collect should help you make logical choices. For example, high class farmer's markets often like more unique varieties than more modest markets. Roadside stands have to cater to the clientele that drives past--- they ask for certain varieties, often old standards, and sometimes only get interested in the newest ones with taste tests and sampling.
No one can recommend certain varieties as a general rule for everyone to plant. For new fruit growers, learning about new and different varieties is one of the most exciting things about the whole project. While it is great to plant some of the really interesting varieties you read about in the catalogs, remember that you want to be able to easily sell your produce to your customer, rather than having to drag him kicking and screaming to a different variety than they think they want, but which you feel is the best thing since sliced bread. A good compromise is required, between your desires and your customer's desires.
To get a quick and dirty idea about the fresh fruit industry, just take a walk down your local supermarket's produce aisle. It will be enlightening and educational, as well as a little disheartening. You usually will see very pretty fruit, but a rather narrow selection of varieties. For example:
After you have familiarized yourself with the basic fruit varieties that your market is looking for, consult with your nurseryman who can often recommend the particular cultivars and specific varieties that will likely do best for you, based on your planting systems, climate, soils, etc. Don't just use a shotgun approach or just personal preference, unless you like to eat a lot of fruit!
