'Siracusano 2KR' originates in Italy, where it probably occurred as a bud sport of the variety 'Femminello' in area south of Syracuse.
The tree is quite vigorous with a dense crown growing primarily vertically and its branches are completely thornless. Young shoots have a hint of purple and the blossoms are white with little purple as well.
'Siracusano 2KR' is a very productive variety, but quite sensitive to mal-secco and wind/hail damage. The fruit is elliptic, medium-sized (130-160g) with a round base and slightly punched out tip. Rind is yellow, slightly grainy and not too thick. Its extremely acidic pulp (more than 6% of acids) is lemon yellow and very juicy, usually divided into 10 segments with thicker membranes and lots of seeds.
The fruit usually ripens in October. Clone 'Femminello Siracusano m 256' was improved with microinoculation and clone 'Femminello Siracusano 2kr' was bred, when the original plant was exposed to gamma rays of Cobalt 60. This new clone was much more vigorous and had thorns. Both these varieties are sometimes listed as different cultivars, not clones.
