Abstract
Evaluation of 17 sesame genotypes were carried out at two locations (Mallawi and Shandaweel Research Stations, ARC) in two successive seasons (1998 and 1999). Combined analysis was done for the four experiments for some characters. The results revealed highly significant differences among genotypes, and years for all studied characters. The same trend was observed for locations effect except for number of branches/plant. The first and second interactions were highly significant for all studied characters.
Wide range of genotypic and phenotypic coefficient of variations were noticed in characters. Heritability estimates for plant height, first capsule height and number of branches per plant were high. The expected genetic advance from selection appeared to be effective, these results proved that phenotypic selection may be useful for these characters. Correlation coefficient between seed yield/plant and other characters was positive and highly significant except for first capsule height. Also, the correlations were positive and highly significant between plant height and all yield components. Results indicated that selection for the studied characters resulted in yield improvement.
