Hamlin Orange
Type and parentage: Sweet Orange
Average diameter (inches): 2 3/4 - 3
Seeds per fruit: 0-6
Commercial harvest season: October - January
Hamlin is the most widely grown early sweet orange in Florida
and the tree among the most cold tolerant. Several selection are available.
Its earliness makes much of its harvest possible before the onset of winter
freezes in Florida. Because of its high yields, Hamlin is the most productive
on the basis of pounds of solids per acre even though solids per box are
lower than for Pinapple and Valencia. Its juice color score is also low,
particularly on lemon-type rootstocks so the juice is blended with that of
other varieties to meet color standards. The fruit of this variety will
develop a good natural color break. Small fruit size can be a problem for
the fresh fruit market, particularly during heavy crop years and when soil
potassium levels are inadequate. The fruit is susceptible to splitting and
creasing and will frequently drop heavily later in the season. There is
apparently little significant effect on the following bloom and fruit set
from holding fruit late on the tree.
