New varieties to combat old problems in Arabica coffee production in Kenya :
A breeding programme initiated in 1971 to produce Coffea arabica varieties resistant to Colletotrichum coffeanum [Glomerella cingulata] and Hemileia vastatrix is outlined. Germplasm screening was followed by the development of elite breeding populations. Ancillary fundamental research was conduced into selection methods and the nature of disease resistance, quantitative characters and hybrid varieties of C. arabica. Work is reported on the multiplication of new disease resistant and compact varieties with a view to making the first batch of seeds available in 1986 and the first seedlings for field planting by growers in 1987
