Abstract
To study the nature and magnitude of gene effects for yield and its components in sesame (Sesamum indicum L.) we carried out generation mean analysis using the following four crosses of different sesame cultivars: VS 9510 x Co1; NIC 7907 x TMV 3; Cianno 13/10x VRI 1; and Si 1115/1 x TMV 3. The P1, P2, F1, F2, BC1 and BC2 of these generations were studied for seven quantitative traits. The analysis showed the presence of additive, dominance and epistatic gene interactions. The additive dominance model was adequate for plant height in the NIC 7907 x TMV3 and Si 1115/1x TMV 3 crosses and for capsule length in the VS 9510 x Co1, NIC 7907 x TMV 3 and Si 1115/1 x TMV 3 crosses. An epistatic digenic model was assumed for the remaining crosses. Duplicate-type epistasis played a greater role than complementary epistasis. The study revealed the importance of both additive and non-additive types of gene action for all the traits studied.
Highlights
Sesame (Sesamum indicum L.) is an ancient and important oil seed crop known in India as til, ellu, beniseed, simsim and Sesame is often referred to by the epithet “the queen of oil seeds ” because it is prized for its nutritive value and for the quality and quantity (44% to 52%) of its oil which is rich in vitamin E and has a significant amount of linoleic acid that can control blood cholesterol levels
The protein content of sesame seed is about 26.25% and the sulfur-containing amino acid methionine is present at a concentration of about 3.4% (Mosjidis, 1982)
Sesame seed oil is resistant to oxidation and rancidity under normal storage conditions
Summary
Sesame (Sesamum indicum L.) is an ancient and important oil seed crop known in India as til, ellu, beniseed, simsim and Sesame is often referred to by the epithet “the queen of oil seeds ” because it is prized for its nutritive value and for the quality and quantity (44% to 52%) of its oil which is rich in vitamin E and has a significant amount of linoleic acid that can control blood cholesterol levels. The mean performance of the BC2 segregating generation was lower than that of the BC1 generation for all crosses and traits except for plant height and number of branches per plant for the Si 1115/1 x TMV 3 cross, number of capsules per plant and capsule length for the VS 9510 x Co 1cross, and seed yield per plant and the weight in grams of 1000 seeds for the VS 9510 x Co 1, Cianno 13/10 x VRI 1 and Si 1115/1 x TMV 3 crosses.
