The Pacific Northwest leads the United States in red raspberry
production. Many factors affect yield, including nutrition,
weather, pests, and water. Most nutritional problems can be
quickly solved once you know the specific problem, but an
accurate diagnosis is difficult.
Foliar nutrient symptoms can be helpful, if you recognize
specific...

The elucidation of the structure of the red pigments of the black
raspberries. Monger variety, was achieved. The components of the
pigment of the berries were (a) cyanidin-3-glucoside, (b) cyanidin-3,
5-diglucoside, (c) cyanidin-3-diglucoside and (d) cyanidin-3-rhamnoglucosido-
5-glucoside. The elucidation was carried out after isolation,
purification, concentration and chromatographic separation of...

Red raspberry, Rubus idaeus L., is a valuable crop for the U.S. Pacific Northwest and clonal propagation is required to produce disease-free plants and for germplasm preservation. One challenge of red raspberry micropropagation is the wide variation in growth response among the cultivars. The studies described in this dissertation were...
This publication describes raspberry cultivars, including red, yellow, black, and purple types. It explains the difference between floricane-fruiting and primocane-fruiting cultivars, includes information on commercial value, and identifies which cultivars work well for home gardens.

This publication briefly describes raspberry
cultivars. The two main types of raspberries are
red and black. Yellow-fruited raspberries result
from a mutation of red raspberries that prevents
the formation of red color; they are grown exactly
the same as red raspberries. Purple raspberries are
a hybrid between black and red...
Seven red raspberry (Rubus Ideaus L.) samples from Oregon, Washington, British Columbia and New Zealand were processed into juice. These, along with three juice samples supplied from West Germany were analyzed by high performance liquid chromatography, (HPLC), for nonvolatile acid, sugar, anthocyanin and anthocyanidin composition. In
order to quantitate the...

The retention of pigments in processed raspberries is a function of the process method and conditions of subsequent storage. The presence of sucrose and the nature of the headspace gas also influences the retention of the pigment. The effect of some of the above variables on the pigments was investigated....

A cultivar comparison study was conducted to identify similarities
and differences in cane characteristics between 2 primocane fruiting
red raspberry cultivars and to determine if the differences and
similarities can help determine cultural practices that may improve
productivity. The comparison of the cultivars 'Amity1 and 'August
Red' showed a difference...

Flavonols and ellagic acid compounds were characterized and measured in 55
experimental and commercial red raspberry juices by high performance liquid chromatography (HPLC) and diode array spectral techniques. Samples were prepared
using Polyamide-6; a fraction eluted with methanol contained <_ 8 quercetin-glycosides,
quercetin and kaempferol. Another fraction, eluted subsequently with...
The oblique-banded leaf roller [Archips rosaceana (Harris)] has become
a major pest of red raspberries in the Willamette Valley. It has a large host
range of cultivated and wild plants. The main concern on raspberries is its
habit of getting into the cups of the fruit. It is only of...
In recent years, there has been renewed interest in black raspberry (Rubus occidentalis L.) breeding. This has been spurred by an increase in black raspberry consumption due to studies that have shown them to be particularly high in anthocyanin content indicating high levels of antioxidants. Present cultivars are ill adapted...
Large raspberry aphid, Amphorophora agathonica, is an important pest in red and black raspberries in the Pacific Northwest. It transmits plant viruses that cause decreased cane vigor and fruit quality, making it a significant pest for growers. This publication includes aphid identification, biology, monitoring techniques, and control methods.

Raspberry bushy dwarf virus (RBDV) is the sole member of the idaeovirus genus of plant viruses. It is a pollen-borne virus that economically impacts both red and black raspberries worldwide. Three strains of the bipartite RBDV have been reported. The common strain found in North America, South America, Australia, New...
'Amity' red raspberries, 'Chester' blackberries and 'Earliblue' blueberries were subjected to different cooling treatments at 0°C and placed in storage at 0°C. Fruits were cooled 2-4 times faster with forced-air cooling than with room cooling. Cooling treatments had no effect on decay, soluble solids content or citric and malic acid...

The effects of fenamiphos on soil and root populations of Pratylenchus penetrans were evaluated in four red raspberry cv. Willamette fields in Northwestern Oregon. Field 1 was a silty clay loam with 53% organic matter (OM). Field 2 and 3 were silty loam soils with 3.25 and 2.55% OM, respectively...
Strawberries {Fragaria ananasa) and raspberries {Rubus ideaus) are good sources ofmany important nutrients, and have great potential to improve human health. However, they are highly perishable and have a very short shelf-life mainly due to the attack of fungi and high respiration rate. Edible coatings, especially chitosan-based coatings have been...
The objective of this study was to characterize an unknown agent associated with decline in black raspberry (Rubus occidentalis) in Oregon. A virus was found consistently associated with decline symptoms of black raspberries and was named Black raspberry decline associated virus (BRDaV). Double stranded RNA extraction from BRDaV-infected black raspberry...
The United States is the third-largest producer of raspberries in the world. Washington

The effects of ¹⁵N-labeled fertilizer applied to mature summer-bearing red raspberry (Rubus idaeus L.) plants were measured over two years. Four nitrogen (N) treatments were applied singularly at 0, 40, or 80 kg·ha⁻¹ of N in early spring (budbreak), or split with 40 kg·ha⁻¹ of N (unlabeled) applied at budbreak...
In recent years, red raspberry production in Washington and British Columbia has been severely limited by a newly emerged virus complex that causes symptoms of crumbly fruit. The complex is comprised of three viruses: Raspberry bushy dwarf virus (RBDV), Raspberry leaf mottle virus (RLMV) and Raspberry latent virus (RpLV). Both...
The Pacific Northwest (Oregon and Washington in the United States and British Columbia in Canada) is one of the major producers of red raspberry (Rubus idaeus L.) and blueberry (Vaccinium corymbosum L.) in the world.

In this area, caneberries typically are planted on Aloha, Jory, Newburg, Willamette, Woodburn, or Saum...
BACKGROUND: Consumption of raspberry products have been observed to produce healthful effects and reduce weight gain and positively shift metabolism in mice fed obesigenic diets. In the past, our lab has successfully shown a reduction in weight gain for mice consuming RPC+HF vs. mice fed HF alone. Currently, there is...
