Abstract

Having knowledge and correct understanding on genetic control and architecture of agronomically important traits are essential keys in breeding programs. In this investigation, genetic parameters of some agronomic traits of seven cultivars and lines of SESAME Ultan, Darab 1, Varamin 2822, Dashtestan 2, Karaj 1, early maturity Palestinian, and TLHE, which were crossed directly and reciprocally, and their progenies (N=42), were evaluated using Greefing method 1 and mixed model B. Analysis of variance results indicated significant differences among the parents and their hybrids for all the traits, except seed oil content, general combining ability (GCA), and specific combining ability (SCA). The reciprocal effects for all traits except seed YIELD were significant. Relative contribution of GCA to SCA indicated that number of capsule in main stem, height of the first capsule, capsule length, and seed oil content were more prominently controlled by genes with additive mode of action, and the rest of the traits were mostly governed by non-additive mode of actions. Estimation of broad sense heritabilities varied from 48.9 to 90.5 for fertile length of the main stem and number of capsule on the main stem, respectively. Number of capsule on the main stem with 67.64% and height of the first capsule with 60.43% had the high narrow sense heritability, indicating the validity of these traits in selections. The analysis was able to define the lines showing the best general combining abilities.
