Abstract
Wheat is one of the most important cereal crops in Kenya. Its production is constrained by both abiotic and biotic factors. The main abiotic factors include acidic soils, drought and sprouting and lodging. The biotic factors are mainly diseases like stem rust, yellow rust and barley yellow dwarf virus and pests such as Russian wheat aphids. I The main objectives of wheat improvement is to develop wheat varieties that are widely adapted, high yield ing, resistant to both abiotic and biotic stresses and have acceptable end use qualities. Various activities are carried out to achieve these goals and they include, crosses, segregating population advancement, preliminary screening for resistance to various stresses, screening of introduced germ plasm and advanced yield trials.
