Influence of host virus content on the acquisition and transmission of barley yellow dwarf virus - 1990 - Printed

14 ref

Oats (Avena sativa L.), wheat (Triticum aestivum L.), and barley (Hordeum vulgare L.) showed wide variations in barley yellow dwarf virus (BYDV) content, as assessed by enzyme-linked immunosorbent assay (ELISA), among different leaves on the same plant, and also between leaves in the same position (i.e., of the same age) on different plants. Selected entire plants and individual leaves were compared as virus sources for the acquisition and transmission of BYDV isolates-Purdue (P)-PAV, MAV, and RPV-by specific (efficient) or nonspecific (inefficient) vectors. Overall, there was no convincing evidence of differences in virus acquisition efficiency
