HS178
The Robinson (Figure 1) is one of the released citrus hybrids originating from a Clementine x Orlando cross made by Gardner and Bellows at the United States Department of Agriculture Station in Orlando in 1942. It was officially released as a cultivar by Reece and Gardner in 1959. Since the fruit is 3/4 tangerine and 1/4 grapefruit, it looks most like a tangerine and is marketed as one even though it is technically a citrus hybrid.
