Abstract
Second generation seed progeny of intra and interspecies hybrids of indicum (IAR-I, IAR-2ESB),sesamum indicum (EGL) and ceratotheca sesamoides (ELL). L. Were evaluated for expression of new traits. Trasgressive segation was observed for four characters studies that have direct bearing on yield as: capsule length, seed per capsule, hundred seed weight and leafiness, Trasgression level and transgressive frequency were determined transgression level was comparatively high for leafiness in most hybirds (1.3-76%), with the highest frequency of 62.5% in IAR-1xEGL and the lowest frequency of 42.9% in EgssLxIAR-1. Conversely, transgression level was comparatively high for leafiness in most hybrids (2.5-53.3%) with highest frequency of 42.9% in ELLx EGL and lowest frequency of 3.7% in IAR-2 xELL hundred seed weight showed little or no transressive segregation except in EGLxELL hybrid with transgression level of 33.3% and transgressive frequency of 37.5%. These findings will invariable give an insight in the basis for selection of desirable genotype for further breeding programs.
