Technical Abstract: Biological variation among 52 isolates ofWheat streak mosaic virus (WSMV) was examined by mechanical inoculation of barley (Hordium vulgare L.), corn (Zea mays L.), oat (Avena sativa L.), pearl millet (Pennisetum glaucum L.), rye (Secale cereale L.), and wheat (Triticum aestivum L.). All 52 isolates caused systemic infection on ¿Lodi¿ oat , ¿Westford¿ barley, `Bonel¿ rye , and `Tomahawk¿ wheat. In contrast, only 6 WSMV isolates infected `Spirit¿ corn , and 11 isolates did not infect pearl millet (94-6667 ). Nine, 11, and 13 WSMV isolates did not infect sorghum lines IS1056, PI550610, and TX626B, respectively, and only 2 infected KS56A. At 18°C, no isolate infected the resistant wheat line KS96HW10-3. However, at 24°C, all but one isolate (EB3) infected this wheat line, indicating that the resistance of KS96HW10-3 wheat was robust at 18C, yet temperature sensitive with repsect to most WSMV isolates.
