Narrative
`Perpetua' (USPP 24,209) is a new ornamental blueberry (Vaccinium sp. L.) from the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) breeding program in Corvallis, OR, released in cooperation with the Oregon State University's Agricultural Experiment Station (Finn 2014). `Perpetua' is the only strongly repeat fruiting (remontant, off-season) blueberry developed from northern adapted germplasm we are aware of. In Oregon, the cultivar flowers in April with other blueberry cultivars, ripens a crop of small fruit in late June, and then begins flowering on new growth in July-August with a second crop in August-September. The plants are fairly compact with lustrous dark green foliage. The name `Perpetua' honors Cape Perpetua along Oregon's Pacific coast and the cultivars appearance of perpetual flowering and fruiting. `Perpetua', tested as ORUS 61-1, was selected in Corvallis, OR in 2005 from a population grown from open pollinated seed of CVAC 45 (PI 296412) growing in the USDA-ARS National Clonal Germplasm Repository collection in Corvallis, OR. PI 296412 was collected from the wild in 1963 in Monmouth, Maine. When the plant was evaluated in the collection, it was noted for its small fruit size and autumn fruiting. PI 296412's characteristics for fruit size, leaf shape, and leaf size are intermediate to those of V. corymbosum and V. angustifolium Aiton (lowbush blueberry). Since both species are found in the region where the accession was collected, it is presumed to be a hybrid between these two species. The commercial highbush blueberry industry in the Pacific Northwest had as one objective the development of a cultivar that was small fruited, that was higher yielding than `Rubel', and could be competitive in the bakery market. Open-pollinated fruit was collected in 2000 from PI 296412 to try to capture the combination of an upright, medium-sized plant with small fruit. The fruit are small (1.2 g; 1.17 x 1.29 cm) and most similar to that of V. angustifolium. `Perpetua's fruit are fairly soft, have a mild flavor and a wet picking scar making them poorly suited for the commercial fruit market but fine for a home garden market. `Perpetua' is introduced as an attractive ornamental blueberry with repeat flowering and fruiting. `Perpetua' should also be useful for birding enthusiasts interested in having a food source to draw birds to their home in late summer. `Perpetua' should be adapted to typical soil environments where blueberries and other Ericaceous plants can be grown. The ultimate cold hardiness and heat tolerance of `Perpetua' is not known, though based on the maternal parent it is expected to have good winter hardiness.

Phenotype Data

CategoryDescriptorDescriptionValueSample SizeStudyInventoryAvailability
DISEASEBlueberry shock virus Ilar virus of Vaccinium growing in the Pacific Northwestern North America. The virus is transmitted by pollen or seed and can be detected by ELISA/RT-PCR. Presence of the virus causes flower and fruit drop. Infection occurs during bloom and the virus moves into other parts of the plant in an uneven but steady manner and may take several years to become fully systemic in mature bushes. In the year after infection, emerging flower and leaf tissues die rapidly at full bloom followed by regrowth. Once symptoms have been exhibited in all parts of the plant, the plant remains asymptomatic in subsequent years. Infection in young plants of some cultivars can stunt the plant for the remainder of its life, however, more typically production is lost for one year.9 Finn, Mackey, Postman, Martin 2017 Shock virus Not Available
