Excerpt from Mosaic Diseases of Wheat and Related Cereals Mosaics are known to occur on winter wheat in 44 counties in 7 States in the United States. The distribution of these diseases is becoming more extended each year, and while they are very destructive under certain conditions there is no cause for alarm because some of these mosaics are controlled by means of resistant or tolerant wheats, All tests conducted thus far have Shown that the viruses occurring east of the Mississippi River are carried In some manner in the soil, the new wheat crop becoming infected therefrom. Tests which have been made with soils from the mosaic-infested areas west of the Mississippi River have given no evidence that the viruses are carried in the soil. Seven wheat mosaics considered distinct are described at tempera tures near 600 F. With a daily photoperiod of 8 hours. These condi tions are taken as standard because the winter-wheat plant responds in an essentially normal manner during the tiller-formation period and because the mosaic symptoms are comparable to those occurring in the field during the early spring growth period. The characteristics of these mosaics are summarized. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
