Loganberry
The loganberry (Rubus × loganobaccus) is a hybrid of the North American blackberry (Rubus ursinus) and the European raspberry (Rubus idaeus), accidentally bred in 1881 by James Harvey Logan, for whom they are named. It is cultivated for its edible fruit.
The plant and the fruit resemble the blackberry more than the raspberry, but the fruit color is dark red rather than black.
The loganberry was derived from a cross between Rubus ursinus (R. vitifolius) 'Aughinbaugh' (octaploid) as the female parent and Rubus idaeus 'Red Antwerp' (diploid) as the male parent (pollen source); the loganberry is hexaploid. It was accidentally created in 1881 in Santa Cruz, California, by the American judge and horticulturist James Harvey Logan (1841–1928).
Logan was unsatisfied with the existing varieties of blackberries and tried crossing two varieties of blackberries to produce a superior cultivar. He happened to plant them next to plants of an old variety of red raspberry, 'Red Antwerp', all of which flowered and fruited together. The two blackberry cultivars involved in these experiments were probably 'Aughinbaugh' and 'Texas Early' (a cultivar of Rubus velox), which were two of the three varieties that Logan had planted in his yard that year.
Logan then gathered and planted the seed from his cross-bred plants. His 50 seedlings produced plants similar to the blackberry parent 'Aughinbaugh', but larger and more vigorous. One was the loganberry; the others included the 'Mammoth' blackberry.
Since Logan's time, crosses between the cultivars of raspberry and blackberry have confirmed the loganberry's parentage, with an earlier theory that the loganberry originated as a red-fruiting form of the common Californian blackberry Rubus ursinus now disproved. Progeny from Logan's original plant was introduced to Europe in 1897. A prickle-free mutation of the loganberry, the 'American Thornless', was developed in 1933.
The tayberry is a similar raspberry-blackberry hybrid. The 'Phenomenal' berry or 'Burbank's Logan', developed by Luther Burbank in 1905, is also a raspberry-blackberry hybrid, but is a second-generation cross (i.e., two first-generation crosses between blackberry and raspberry were then crossed to each other). Other similar hybrids include the nessberry, which is a cross between a dewberry and a red raspberry, and youngberry, a three-way cross between blackberry, raspberry, and dewberry.
The loganberry has been used as a parent in more recent crosses between various Rubus species, such as boysenberry (Loganberry × raspberry × blackberry x dewberry), the Santiam blackberry (loganberry × California blackberry [R. ursinus]), and the olallieberry (Black Logan × youngberry). The loganberry is part of the ancestral line leading to the Marionberry, a common and popular berry grown mainly in Oregon.
