Breeding for improved oilseeds has traditionally emphasized improvement in yield, oil content and disease resistance. Improved protein has been sought by some breeders in recent years. The soybean varieties Provar and Protana were released in 1969 because they contain higher protein percentages than other varieties. Glandless cotton varieties are being bred by public and private breeders. Two glandless varieties have been released by commercial breeder‐seedsmen, but one has been withdrawn because of low yield. It probably will be several years before glandless varieties are of commercial significance. Safflower germplasm has been screened and a source of improved lysine has been identified. This lead may be pursued, but major problems of disease susceptibility and high fiber content also demand attention. Emphasis in sunflower programs will be on developing higher yielding lines and on exploiting the possibility of developing hybrids. Sunflower research personnel is so limited that there is not likely to be any major effort on quality factors for some time. Sesame research is very limited, major emphasis being on control of shattering.
