ACHIEVEMENTS AND PROSPECTS - THE BRITISH COLUMBIA RED RASPBERRY BREEDING PROGRAM |
| Authors: | H.A. Daubeny, A.K. Anderson |
| Abstract:
British Columbia has had an active red raspberry breeding program for more than 30 years. Successful cultivars originating from the program include 'Chilliwack', 'Skeena' and 'Chilcotin'. In recent years, emphasis has been placed on broadening the genetic base by using parents that are backcross derivatives of various Rubus species, including Rubus occidentalis L., R. crataegifolius Bge. and R. phoenicolasius Maxim. These derivatives were obtained from the programs at the Scottish Crop Research Institute and/or Horticulture Research International at East Mailing. 'Tulameen', which was released in 1989 and has attracted much interest, has R. occidentalis in its derivation. Selections with superior fruit qualities, now being considered for cultivar status, have genes derived from R. crataegifolius and R. phoenicolasius. Second and third backcross derivatives of hitherto unexploited selections of the native North American red raspberry, Rubus strigosus Michx., are being used as sources of resistance to Amphorophora agathonica Hottes, the North American aphid vector of the rasberry mosaic virus complex and to Phytophthora fragariae var. rubi Wilcox & Duncan, one of the main causal organisms of root rot. Several of the derivatives have fruit qualities approaching commercial acceptance. | |
