ENCLOSURE TO PART I11. anticipated that their comparison may throw some interesting light on the amount of combined damage due to boll worm, jassid and stainer attack. ProGrRAMME oF WORK For 1926-27. This will not be decided upon definitely until it is known whether the additional assistant Plant Breeder will arrive from the U.K. in time to help with the lay-out and planting of next year’s experiments. The following, in brief, is an outline of the work to be undertaken, if all goes well : — 1. Meteorogolical observations and recording of same. > Growth in observation lines of some seventy varieties of Cotton, which, to the writer’s knowledge, have not been grown in Southern Rhodesia previously : (a) On unmanured land; and (b) on heavily manured land, with the object of discovering a variety or selection from a variety which will give a dwarf or medium sized plant, when crown in rich soil. 3. Growth in observation lines of field selections made last season under conditions (a) and (b), as indicated above. t Recording usual observations and measurements on selected plants of each variety and strain, grown on the station. A repetition of the variety trials conducted last year, with a view to ascertaining to what extent such trials can be relied upon. A comparison of Cotton plants grown: (a) in the insect proof cage, with (b) Cotton plants of the same variety grown under field conditions. Observation rows from seed of the different varieties, grown under cage conditions last year, with a view to noting whether or not any crossing has taken place. ** Increase *’ or *‘ small bulk ”’ plots, of what appears to be the better varieties among those which were grown in last year’s variety trials. The results of these trials are not yet to hand, nor is 1t likely that they will give any indications when they arrive, but three out of the five varieties appeared to be much better than Improved Bancroft. OTHER CROPS. Maize was grown on the Cotton Breeding Station last year to avold having to purchase food for the native labour. The resulting crop yielded so well, however, that it is proposed to sell it to local farmers, from whom there is a strong demand for seed. Potatoes, monkey nuts and vegetables all yielded good crops: it is proposed to continue growing them in rotation with Cotton. (Sgd.) G. S. Cameron. August, 1926. 162
