REPORT OF AN IMPERFECT RUST OF WHEAT FROM EAST PAKISTAN
Abstract: The author collected wheat stems having elongated rusty pustules from the experimental farm of Agricultural Research Institute, Tejgaon, Dacca in February, 1969. On microscopic examination, a diseased stem of the specimen revealed new form of uredospores different from the type found on wheat plants in East Pakistan. In a T.S. of the stem, the single-celled sessile uredospores were found to be produced in definite cavities below the epidermal layer of the stem as shown in Fig. 1. The sessile uredospores remained crowded in cavities. The characteristic features of the uredospores is shown in a peei ng of the rusty pustule in Fig. 2. The uredospores on the average measured 23.5^ in diameter.
