Investigation on variability and diversity estimates of eight yield and yield contributing characters viz., plant height at first flower (PHFF), number of branches per plant at maximum flower (NBPMF), plant area per plant (PAPP), number of pods per plant (NPdPP), pod weight per plant (PdWPP), number of seeds per plant (NSPP), seed weight per plant (SWPP) and plant weight per plant (PWPP) were carried out in six irradiated lentil lines in 2005-2006 and 2006-2007. Presence of wide range of variation of all the characters indicated that they are quantitative in nature and are under polygenic control. The lines were genetically well differentiated as indicated by the analysis of variance. Significant differences among the doses for most of the characters showed that the four irradiation doses included in the analysis were different from each other. Significant year and dose and respective interaction items with lines for most of the characters indicated that the environments were different and they interacted with genotypes differently. Lines, years and doses interacted among themselves as indicated by significant L×D×Y. Heritability and genetic advance were estimated to be low for all the characters under study. However, the different components of variation and coefficient of variabilities, as calculated were more or less high for PAPP, NSPP, NPdPP, NBPMF and PHFF which indicated a wide scope of improvement of these traits through selection.
