Abstract :The inheritance of the morphogenetical characters determining the plant types, maternal and cytoplasmic effects on oleic and linoleic acids in sesame was determined. The results obtained from the F 1 generation indicated that 1); bicarpellate capsule was dominant over quadricarpellate, 2); single capsule per leaf axil was dominant over three-capsule 3); branched stem type was dominant over non-branched stem type, 4); lobed leaf shape was dominant over simple or ovate leaf shape, 5); hairiness was dominant over hairless, 6); colored seed coat color was dominant over white seed coat color. The results obtained from the F 2 generation indicated that inheritance of all these characters mentioned above were monogenic with 3:1 segregation ratios. it was not only obtained 3:1 segregation ratios but also epistatic segregations as 9:4:3 and 9:3:4 ratios for seed coat color. Although the maternal effect on oleic and linoleic acids were found high, the cytoplasmic effect was found to be negligible level.
