“…The raspberry cultivars selected for this study were the resistant ÔTulameenÕ and susceptible ÔVintage,Õ a new release from the USDA Horticultural Crops Research Unit and Oregon State University cooperative breeding program. Tulameen was selected for aphid resistance conferred by gene Ag 1 (Daubeny andAnderson 1991, Daubeny andKempler 2003). Vintage and Tulameen plants were obtained as hardened-off tissue culture plugs from Sakuma Brothers (Burlington, WA).…”

The aphid Amphorophora agathonica Hottes (Hemiptera: Aphididae) is an important virus vector in red (Rubus idaeus L.) and black (Rubus occidentalis L.) raspberries in North America. Raspberry resistance to A. agathonica in the form of a single dominant gene named Ag1 has been relied upon to help control aphid-transmitted plant viruses; however, the mechanism of resistance to the insect is poorly understood. Aphid feeding was monitored using an electrical penetration graph on the resistant red raspberry 'Tulameen' and compared with a susceptible control, 'Vintage'. There were no differences in pathway feeding behaviors of aphids as they moved toward the phloem. Once in the phloem, however, aphids feeding on resistant plants spent significantly more time salivating than on susceptible plants, and ingested significantly less phloem sap. This suggests that a mechanism for resistance to A. agathonica is located in the phloem. Reduced ingestion of phloem may result in inefficient acquisition of viruses and is a likely explanation for the lack of aphid-transmitted viruses in plantings of resistant cultivars.

“…This was not considered important as commercial growers in BC routinely use a spray program to control fruit rot. This fungicide spray program is also very effective in controlling cane diseases, including anthracnose, and the release of 'Qualicum,' an anthracnose susceptible cultivar, was therefore not a concern in BC ( Daubeny and Kempler 1995 ) . Most breeding programs follow a minimal spray program in their selection trials.…”

“…One possible reason for this may be that the majority of the fi elds in the Pacifi c Northwest are planted to nonresistant cultivars, like 'Meeker' and 'Willamette' (Kempler, personal observation). Several aphid-immune cultivars have been released from the AAFC-PARC program, including: 'Haida, ' 'Nootka,' 'Skeena,' 'Qualicum,' 'Malahat,' 'Cowichan,' 'Esquimalt,' 'Chemainus,' and'Saanich' (Daubeny 1973, 1978a, b ;Daubeny and Kempler 1995 ;Kempler and Daubeny 2000 ;Kempler et al 2005aKempler et al , b, 2006Kempler et al , 2007 . 'Algonquin,' also from the AAFC-PARC program, has been identifi ed as homozygous for gene A g 1 with apparent lack of segregation when 'Algonquin' is used as parent.…”

“…'Algonquin,' also from the AAFC-PARC program, has been identifi ed as homozygous for gene A g 1 with apparent lack of segregation when 'Algonquin' is used as parent. Its resistance was inherited from 'Haida' and 'Canby,' which are heterozygous for gene A g 1 (Daubeny and Sjulin 1984 ) . It is essential that further genetic sources of aphid resistance are identifi ed to ensure continued success of this control stratagem.…”

The red raspberry, Rubus idaeus L., is a valuable crop that has recently increased in production, generating a large interest in commercial ventures and in research. Traditionally, most of the crop has been sold to processors for freezing, jam production, canning, juice and fl avorings for ice cream, yogurt, and other products, but in recent years fresh market production has increased and become a very important sector of this industry. There has been an increased interest in black, purple, and Arctic raspberries because of their high nutraceutical value. R. idaeus, a diploid (2 n = 14), is included in the Idaeobatus and is the most important commercial species in this subgenus. The fl owers are hermaphroditic; however, in some cases, they are unisexual, especially among wild species. Domestication of raspberries is comparably recent as it occurred less than 500 years ago. Red raspberries are widely distributed in all temperate regions of Europe, Asia, and North America with the greatest diversity in China. Enriching the cultivated gene pool by incorporating the unique genetics from wild germplasm to meet the challenges that lie ahead is desired. Breeding goals are the improvement of fruit quality which includes selection for better preharvest hanging ability and postharvest shelf life and processed quality. Resistance to heat and cold and resistance to pests and disease are also important, as well as large fruit size, good presentation, and ease of harvest. Fruit color of the newer cultivars varies from very dark red to a light orange-red and there has become a tradition of cultivar selection (eds.), Fruit Breeding, Handbook of Plant Breeding 8, DOI 10.1007/978-1-4419-0763-9_8, © Springer Science+Business Media, LLC 2012 264 C. Kempler et al.specifi cally for processing or for fresh market. There are now approximately 50 active raspberry breeding programs in 26 countries, mostly in Europe and North America. Use of molecular markers for genetic studies and mapping is referenced; however, in this crop, it is at an early stage with only a few genes mapped.

The &ect of a mtura2 clay adsorbent on quality retention in modified atmosphere packaged raspbem'es (Rubus idaeus L., cvs 'Chilliwack ', 'Malahat ', and 'Quulicum 7 was rested. Fruit packaged with the natural clay adsorbent was much finner, had less decay, andhad fewer dark red overripe fnu't afer 14 days than those packuged without any adsorbent. The addition of the mural clay adsorbent almost eliminated all the condensation inside the package ajier 14 &ys of storage at IC. The reaktion in &cay on the fnrit could be attributed to the reduction in condensed water in the package. However, @em on firmness retention and the slowing of ripening of the fnrit could not be attributed to any measured effect of the clay in this study. The results suggest thar a water/ volatiles ahorbent, such as the natuml cloy used in this study, could be useful in prolonging the shelf-life and improving the quality of modified atmosphere packaged red raspberries grown in a wet climate.
