Prunus necrotic ring spot ilarvirus and prune dwarf ilarvirus in US germplasm collection
It was reported at the 1992 APS/MPS Annual Meeting of the American Phytopathological Society that the National Germplasm Repository - Davis Prunus collection had been tested for the infection by prunus necrotic ring spot ilarvirus (PRNSV) and prune dwarf ilarvirus (PDV). Of the approximately 1600 plants of the collection 345 tested positive by ELISA. Two hundred plants were infected by PNRSV, 33 by PDV and 112 were infected by both viruses. The collection will be tested every year for virus infections. Accessions taken from the collection and tested positive will undergo heat treatments to produce virus-free material.
