Abstract
D.C. x Ceres R 64, a popular premium class wheat selected at Njoro and released in 1953 from departmental control for general cropping, has been attacked by Pyrenophoratritici-repentis (Diedicke ex Dreschler) Dreschler (Helminthosporium tritici-repentis Diedicke). Samples of infected R 64 were sent in to the laboratory, originally from Londiani (7,600 ft.) in October (a further sample being received on request in November), and from Kipipiri (8,300 ft.) in December, 1953. A third sample which mayor may not have been infected was received from Njoro (7,100 ft.) in December. Further samples, both infected and free of disease, were received on requestfrom various farmers in other areas.
