Apple fruit set and quality under contrasting pollination treatments for multiple apple varieties from multiple countries

These data include information on fruit set and fruit quality (size, weight, seed number, sugar content and firmness) of apples grown under different pollination treatments including pollinator exclusion (no visitation by insects), open pollination (visitation by insects) and supplementary pollination (hand pollinated). Data were collected as part of several projects, and include data on multiple different varieties of apples from several different countries.
