Pea streak virus (Marmor trifolii Holmes) is widespread and
occasionally destructive in Eastern Oregon and Washington, and in
many other pea growing areas. Since control by the use of insecticides
to kill the insect vector is only partially successful, resistant
varieties of peas are needed.
In a study to confirm...
The relationship between pea enation mosaic virus
(PEMV) and aging pea aphids was studied. Although this
research initially emphasized the relationship between the
decline in the rate of PEMV transmission and the 'concentration
of PEMV within pea aphids, aphid age was found to be
the principle factor influencing transmission. Enzymelinked...
Biological, serological, and molecular characteristics
of the P4 pathotype of pea seedborne mosaic potyvirus
(PSbMV) were investigated. The characterization allowed P4
to be differentiated from other pathotypes of the same
virus.
P4 was distinguished from P1 on the basis of host
symptomatology. It induced varied, but often distinctive
symptoms in...

Pea seed-borne mosaic potyvirus pathotype 1 (PSbMV-P1) has the ability to infect most genotypes of Pisum sativum. The exception are those genotypes that are homozygous recessive for the sbm-1 gene. The life cycle of PSbMV pathotype 4 (PSbMV-P4) is unaffected by the sbm-1/sbm-1 genotype. Infectious clones of Pl-P4 recombinants were...
The inheritance mode of pea-resistance to the Lentil
Strain of Pea Seedborne Mosaic Virus (PSbMV-L) was
studied. In addition, commercial pea cultivars, Plant
Introduction (P.I.) lines and Oregon State University
(OSU) breeding lines were tested for susceptibility to
this virus. These lines were also tested for their
reaction to Bean...
