Field and growth chamber experiments were conducted to
determine chloride effects on the progress of stripe rust disease
caused by Puccinia striiformis West., and to investigate turgor
potential as the mechanism of the chloride effect.
Seven winter wheat (Triticum aestivum) cultivars were
grown in the field in 1982 and 1983...
Barley is the fourth most important cereal crop in the world because of its broad adaptation, its utility as a feedstock and for human food, and the superior properties of barley malt for brewing. Three of the most important foliar diseases of barley, on a worldwide level are: barley leaf...
Stripe rust (Puccinia striiformis f. sp. tritici) has been receiving
increased attention in the USA since the appearance of more virulent races
detected in the past decade. These races caused yield losses even in areas
where the disease previously was rarely detected. Host plant resistance is the
most cost effective...
The physiologic specialization of nine isolates of stripe rust
(Puccinia striiformis West.) collected in the Pacific Northwest
was determined. The separation of races was based on the differential
susceptibility of the following wheat varieties: Cappelle
Desprez, Chinese 166, Dippes Triumph, Druchamp, Etoile de
Choisy, Flamingo, Gaines, Golden, Ibis, Leda, Michigan...
The virulence of 44 isolates of stripe rust (Puccinia striiformis
West.) from 33 collections made during 1971 and 1972 were characterized
on two sets of differential varieties. The varieties in the
"Oregon" set were: Cappelle Desprez, Chinese 166, Dippes Triumph,
Druchamp, Etiole de Choisy, Flamingo, Gaines, Golden, Ibis, Leda,
Michigan...
Disease has been implied as an important selective
force acting in plant populations. This study was
conducted to determine the effects of stripe rust (Puccinia
striiformis) on the population dynamics of wheat (Triticum
aestivum) cultivar mixtures.
Five wheat cultivars were grown in pure stands and all
possible mixtures at three...
The need to identify a simple but accurate method of stripe rust assessment that best predicts host response prompted this investigation. The study was divided into two plot types, one protected with the fungicide Bayleton and the other unprotected. Ten winter wheat cultivars were used and evaluated. Grain yield, test...
