“…These were 'Lloyd George' and 'Pyne's Royal,' derived from R. idaeus, and 'Preussen,' 'Cuthbert,' and 'Newburgh' that are derived from R. idaeus and R. strigosus. Extensive accounts of early domestication of raspberry are given by Daubeny ( 1996) , Jennings ( 1988) , Roach ( 1985 , Hancock ( 2008 ) , andHall et al ( 2009 ) . Cultivated forms of raspberries are very different from their wild relatives.…”

“…'Heritage,' the most important primocane-fruiting cultivar, was released in 1969 from New York Agricultural Experiment Station (Geneva), and it became the standard in growing regions, where cold winter temperatures caused damage to canes of fl oricane-fruiting raspberries (Daubeny 1996 ) . 'Latham' and 'Chief' released from the University of Minnesota program are valued by breeding programs for their root rot resistance (Finn and Hancock 2008 ).…”

“…Best resistance is achieved when we place an increased emphasis on diversifi cation of the genetic base of resistance by utilizing indigenous populations of R. idaeus, R. strigosus , and other related species. Daubeny ( 1996 ) and list species with the most useful donor traits that successfully cross with R. idaeus . Future exploitation of species germplasm has the potential of introducing valuable resistant traits.…”

“…A Mediterranean-type climate is ideal, with ample rain during the winter months and springtime, when plant growth and development are very rapid, followed by a dry period, supplemented by drip irrigation during the harvest season. Winter months need to have suffi ciently low temperatures to meet chilling requirements but not too low to result in winter damage to canes and fl ower buds (Daubeny 1996 ) . The expansion of raspberry growing to suboptimal environments and less favorable conditions has meant more emphasis on breeding for adaptation to adverse soil conditions, a greater temperature range, adverse winter conditions, and low chill conditions.…”

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.

“…Water condensation in packaged raspberries encourages development of decay (Daubeny and Pepin 1975;Sommer 1992). Work with packaged mushrooms and tomatoes has shown that water adsorbents in packages can improve quality retention for these products (Shirazi and Cameron 1992;Roy er al.…”
