Abstract: A nalyses of 410 sesame germplasms showed that the averag oil content was 53,13%and its C, V,content was 26,39%with its C, V, being of the protein content to the oil content was 3,53%.The average 7,03%, The regressionwas established as follows: protein oretic value of the oil content)Sesame oil was composed of six=68.6621-0,5885 X (the content fatty acids, Among them,acids counted for more than 80%。Path analyses of fattyotein).and linoleic componentsto the oil content sho wed that direct path coefficientsoleic and plasms with oil percentages above 56%were selected, And these materials were also rich in protein, oleic and linoleic acids, The relation between the seed colour and the nutrient quality was also discussed, The oil content tended 'to decline with darker seed colours, indicating that the colours of sesame seeds evolved from black to brown, to yellow and to white.

Key words: Sesame germplasm, Nutrient quality, Seed colour
