ALHAMBRA [_Prunus triflora_ × _Prunus cerasifera_ × _Prunus domestica_] × [(_Prunus simonii_ × _Prunus triflora_) × (_Prunus americana_ × _Prunus nigra_)] =1.= _Vt. Sta. Bul._ =67=:5. 1898. =2.= De Vries _Plant Breeding_ 213. 1907. Although it is over a decade since Alhambra was offered to fruit-growers, it has made little headway in popularity and is chiefly of interest because of its breeding. It is not often that we can trace the pedigree of a plant for more than one or at the most two generations, but in Alhambra we are particularly fortunate. Luther Burbank, the originator, began by crossing Kelsey and Pissardi, and the offspring from this cross was fertilized with Agen pollen. This tri-hybrid was in turn fertilized with pollen from a complex hybrid of a cross of _Prunus simonii_ and _Prunus triflora_ pollinated by a cross of _Prunus americana_ and _Prunus nigra_. As might be expected, the offspring of this final cross was extremely variable and from it was selected the Alhambra. The variety was named by the originator in 1898. The fruit as described by Waugh is “egg-shaped, large or very large; cavity medium shallow, abruptly rounded; suture shallow; apex pointed; color dark, dull red; dots many, small, yellowish; bloom thin, purplish; skin firm; flesh yellow inside, reddish outside; stone medium to large, flat, pointed, nearly smooth, clinging; flavor brisk subacid; quality first rate.” ALTHAM _Prunus domestica_ =1.= _Jour.
