Genetic analysis of drupelet count in black raspberry (Rubus occidentalis)

Raspberry indexing in British Columbia demonstrated that several varieties are carrying a latent virus that induces mild symptons in other red raspberry varieties and severe symptoms on black raspberries (Rubus occidentalis L.). The name black raspberry necrosis is proposed for the disease and virus. The virus is transmitted by the aphid Amphorophora rubi Kalt. It may be acquired by the aphid after a half-hour feeding and transmitted with a two-minute transfer feeding. Most aphids lose their ability to transmit the virus within one and a half hours after leaving the source of inoculum.

Leaf Symptoms

An apparently undescribed Amphorophora was received from Richard Stace-Smith of the Canada Agriculture Plant Pathology Laboratory, Vancouver, B.C., Canada. This species produced leaf symptoms on Munger black raspberry, Rubus occidentalis, which differed from anything associated with the feeding of Amphorophora rubi (Kaltenbach). An examination was made of the material by Professor M. A. Palmer, Dr. F. C. Hottes and the writer. This failed to place this blackberry aphid as a described species. Therefore, it is here described as new.

Amphorophora Agathonica

The large raspberry aphid (Amphorophora agathonica Hottes) is an important vector of viruses in Rubus L. across North America. Although breeding for aphid resistance has long been recognized as an important tool for protecting red raspberries (Rubus idaeus L.) from viral infection, this is the first report of resistance to A. agathonica in black raspberry (Rubus occidentalis L.). Seedlings from 132 wild populations of black raspberries, representing the species' native range, were screened for resistance to A. agathonica. Strong resistance was found in three of these populations, one from Ontario (ORUS 3778), one from Maine (ORUS 3817), and one from Michigan (ORUS 4109). Resistance to the large raspberry aphid in ORUS 3778 and ORUS 3817 is dominant and appears to be conferred by different genes. We propose that the genes for resistance in ORUS 3778 and ORUS 3817 be designated Ag4 and Ag5, respectively. Resistance to A. agathonica in ORUS 4109 also appears to be controlled by a dominant allele at a single locus, but cannot be differentiated from Ag4 at this time.
