Nineteen promising sesame lines, including 3 control cultivars, were evaluated during kharif 2003 for grain yield and its components (days to first flowering, days to 50% flowering, days to maturity, plant height, number of primary branches, number of productive capsules per plant, 1000-grain weight, total dry matter and harvest index), as well as oil quality traits (oil stability, palmitic, stearic, oleic and linoleic contents, and nutritional quality). There was a wide range of variability in the lines for yield and related traits. This can be further utilized for the development of high-yielding cultivars with improved oil content and oil stability index. The nutritional quality of sesame oil be improved by increasing the linoleic acid content, which simultaneously reduces the saturated fatty acid, mainly stearic acid. Oil stability can be improved by improving the oleic acid content. However, it is difficult to improve both oleic and linoleic acid contents simultaneously. More emphasis should be given on primary branches per plant, plant height, total dry matter, 1000-grain weight and oil content to increase the yield. For this purpose, PKDS-37, MACSS 01, Uma and TAC-89-309 can be used. Genotypes OCS-36/2002 and OS-Sel-117 can be used to develop high-oleic cultivars with high oil stability index.
