Summary
Introduction
According to Seegeler (1983), 328 oil plant species are known to exist in Ethiopia. Of these, 15 are cultivated and the rest may have uses other than for oil and may be cultivated or wild. Oil-bearing plants having oil contents in excess of 10 per cent, but which are not yet cultivated commercially, have been catalogued by Goshe & Hamito (1983) (Table 1).
Ethiopia is known to be either a centre of origin or a centre of diversity for many cultivated oil crops. Several of the cultivated oilseed crops play an important role in the nutrition of the Ethiopian population and in foreign exchange earnings. The oil crops currently in production in the country are niger or noog, rapeseed, Ethiopian mustard or gomenzer, linseed, sunflower, sesame, groundnut, safflower and castor bean.
The overall objective of the research programme is to increase the production of oil seeds for food and to provide raw materials for agroindustrial development. This can be achieved by the development of high-yielding, stable cultivars with the necessary package of practices required for sustained high yields. The programme therefore falls into three sections:
– the improvement of noog, linseed, sesame and safflower which possess a wide range of variability and a wealth of unutilized indigenous germplasm;
– the improvement and popularization of oil seed Brassica and groundnut for which a wide range of indigenous germplasm is also available;
– the popularization of the introduced sunflower crop, for which probably no indigenous germplasm exists.
