Comparison Of 4 Varieties Of Spring Wheat For Resistance To Russian Wheat Aphid And Hessian Fly

Evaluation of wheat (triticum SPP.) resistance to the russian wheat aphid (diuraphis noxia mordvilko)

Characterization of resistance components to russian wheat aphid diuraphis noxia (mordvilko) in several wheat (triticum SPP.)genotypes

Inheritance of Russian Wheat Aphid Resistance in Spring Barley Germplasm Line STARS-9577B

A damage rating scale for wheat and barley seedlings was developed by Webster et al. (1991) based on visual The Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), rating of leaf chlorosis, leaf streaking, and leaf spotting. has become a major pest of barley (Hordeum vulgare L.) in the This visual rating was on a scale of 1 to 9 (1 no western USA. STARS-9577B (PI 591617), a six-rowed, sprin...

Comparison of chlorophyll and carotenoid concentrations among Russian wheat aphid (Homoptera: Aphididae)-infested wheat isolines.

Russian wheat aphid, Diuraphis noxia (Mordvilko), feeding injury on 'Betta' wheat isolines with the Dn1 and Dn2 genes was compared by assessing chlorophyll and carotenoid concentrations, and aphid fecundity. The resistant Betta isolines (i.e., Betta-Dn1 and Betta-Dn2) supported similar numbers of aphids, but had significantly fewer than the susceptible Betta wheat, indicating these lines are re...

Glycoproteins from Russian wheat aphid infested wheat induce defence responses.

Elicitors are molecules which can induce the activation of plant defence responses. Elicitor activity of intercellular wash fluid from Russian wheat aphid, Diuraphis noxia (Mordvilko) infested resistant (cv Tugela DN), and susceptible (cv Tugela), wheat (Triticum aestivum L.), was investigated. Known Russian wheat aphid resistance related responses such as peroxidase and beta-1,3-glucanase acti...
