Wheat bushy dwarf disease is a common viral disease in wheat producing areas in Xinjiang in recent years. In 1978-1982, we carried out a number of investigations on this disease, initially concluding that the occurrence of wheat cluster dwarf disease in Xinjiang is basically the same as that reported in the Mainland. Symptoms The typical symptoms of wheat clumpy dwarf disease is severe dwarf plants, increased tillers, the formation of a significant cluster of short symptoms. At the beginning of sickness, the new leaf base appeared intermittent yellow-white short slender spots, and soon after the short thin stripes connected, even into the yellow-green and white stripes. Later, the green stripes gradually disappeared. The lower leaves of the plants were dark green and the leaves hardened. The upper leaves were greenish with obvious or not obvious yellow-white stripes, increased tillers, and apparently dwarfed.
