SOURCES OF RESISTANCE TO WHEAT STEM RUST IN EAST AFRICA

Abstract
The stem rust reactions in the field and greenhouse of 38 wheat cultivars previously selected for resistance in Kenya are presented. A group of these cultivars had good resistance to the main races found in Canada. The cultivars appear to have a diversity of types of resistance, and there is evidence that their resistance results from the action of genes not previously identified. The 38 cultivars constitute a resistance gene pool that should facilitate the breeding of wheat cultivars resistant to stem rust in Kenya.
